ON VARIATION IN SWAHILI: CURRENT APPROACHES, TRENDS AND DIRECTIONS

NICO NASSENSTEIN & DAISUKE SHINAGAWA

This overview paper aims to present general approaches to variation in Swahili, both from a structural/typological and from a sociolinguistic angle. Recently, building upon earlier dialectological studies of Swahili, varieties in the periphery have been the focus of scholarly attention, as well as urban dialects from East and Swahili in the diaspora. This introductory paper intends to summarize some of the approaches and directions that address the geographical and sociolinguistic diversity of Swahili, studied from different angles. These include both traditional approaches (descriptive sketches, dialectological and dialectometrical analyses, lexicostatistics etc.) and more recent directions in Bantu studies, such as micro-parametric analysis in the field of microvariation. Moreover, current (socio)linguistic trends are discussed, which mostly deal with contact, diversity and change in touristic settings, in relation to new media, and in regard to youth language practices, or with new approaches to urban fluidity such as metrolingualism and translanguaging. In this contribution, we aim to give an overview of current trends in the study of Swahili by analyzing processes of linguistic and scholarly diversification and variation in the Swahili-speaking world.

1. On the study of contact, change and variation in the Swahili-speaking world This introductory paper for the present volume intends to offer an overview of the previous studies on Swahili1 as a macro-language consisting of diverse varieties, and to give an outline for current approaches, as well as directions for future investigations. As is generally understood, the earliest attempts at linguistic descriptions of were made as early as in the mid-19th century by linguists, notably (Krapf & Rebmann 1850, Krapf 1882) and (1870, 1894) 2 , which provided the grounds for its standardization, implemented in the early 20th century. In the post- independence era, linguistic studies of Swahili have developed in vast areas of established fields, ranging from sociolinguistics (Polomé & Hill 1980, Mazrui & Mazrui 1995, among

1 The established label Swahili is used throughout the present paper in order to refer to the Bantu language Kiswahili and its varieties. For specific dialects, both forms (e.g. Kiunguja and ) are used, depending upon the cited sources and their preference. 2 While Krapf & Rebmann worked on the Kimvita dialect spoken on the Kenyan coast and in the area, Steere focused on Kiunguja (), while Sacleux (1939) described “Kimrima”, later subsumed under Mtang’ata and Lugha ya Zamani by Nurse & Hinnebusch (1993: 10-11), spoken around in today’s . These three are often commonly cited as competing prestigious dialects in the study of Swahili and the scholarly description of the language. NICO NASSENSTEIN & DAISUKE SHINAGAWA

others) to formal linguistics, which includes historical linguistics (Nurse & Spear 1985, Nurse & Hinnebusch 1993, among others), synchronic analyses (numerous monographs on different varieties), dialectology (Nurse 1982, Möhlig 1995, Heine & Möhlig 19803), detailed studies on specific grammatical topics (Amidu 1997, 2006, and various others), reference sketches and grammars of the standard variety (Ashton 1944, Polomé 1967, Schadeberg 1992, Mpiranya 2015), and so forth.4

In addition, reflecting its nature as the most wide-spread in and parts of Central Africa, contact varieties of Swahili have been in the scope of scholarly attention since at least the late 1970s (see also Shinagawa, this volume), with a focus on pidginized or creolized varieties as well as on processes of pidginization/creolization in Swahili (Polomé 1963, 1968, Heine 1973, University of Hawai’i Press 1975, Nurse 1997, Heine & Kuteva 2007: 166-209) and processes of lexical and structural borrowing. There have been few methodological or inter-disciplinary platforms for the study of such varieties, and this is what the present volume aims to provide (as the first output of a larger Swahili project, based at TUFS, Tokyo, and mainly coordinated between both authors’ universities). In order to build such a common ground for the integrated study of Swahili varieties, not limited to those which have emerged from language contact but including those characterized by different sociolinguistic, historical, or regional backgrounds, we introduce two guiding methodologies that have recently been developing in the broader context of African linguistics, namely i) the micro-typological investigation of structural variation, and ii) the practice-based documentation of sociolinguistic variation, which will be further discussed in Sections 4.1 and 4.2, respectively.

On the other hand, from a geographical point of view, the spread of the language further westwards to , , and within the DR Congo triggered the emergence of new varieties due to contact with local Bantu , Nilo-Saharan languages and official languages such as French. Despite academic awareness of these contact varieties, they were seldom described and had long been outside the scope of intensive investigation. Their reasoned classification was barely possible due to the scarcity of linguistically reliable descriptions, except for sporadically published monographs and overview papers (for example Kaji 1985, Schicho 1980, 1981, 1982, Kapanga 1991, De Rooij 1996, Goyvaerts 2007, Wilt 1988, etc.). This situation, however, has recently changed due to a series of publications of grammatical overview sketches of these “peripheral” varieties (Ferrari et al. 2014,

3 Heine & Möhlig’s descriptive, partially sociolinguistic “Language and Dialect Atlas of ” was a seven- year project (1973-1980) and aimed at covering the entire linguistic diversity found in Kenya; it was not restricted to or Swahili alone. 4 A more detailed list of available sources is found in relevant paragraphs of Section 3.

Nassenstein 2015, Nassenstein & Bose 2016, Nassenstein & Dimmendaal 2020). In the next section, we first deal with the historical process of the spreading of Swahili that explains the current distribution of Swahili varieties and provides an overall picture of its geographical classification, reflecting current findings.

Apart from an expanding focus on remote geographical settings, more recent studies have also looked at hitherto underrepresented topics in the study of Swahili, such as the nexus of language in touristic settings along the East African coast (Storch 2018, Mietzner & Storch 2019), language and social media (Hillewaert 2015) and more exhaustive studies of Swahili- based youth language practices diffused in , , and (Shinagawa 2007, Mulumbwa 2009, Beck 2015, Nassenstein 2016a, Githiora 2019, and many more). These studies in the fields of Sociolinguistics and Linguistic Anthropology have profited from a less essentialist and a more critical approach to contact processes in the Swahili-speaking areas of Africa, such as codeswitching (Myers-Scotton 1993, Blommaert 1992, Goyvaerts & Zembele 1992), metrolingualism, translanguaging, polylanguaging and others (see also Section 5; see also Kutsukake & Yoneda, this volume).

The present overview, as an introduction to an edited volume on aspects of variation in a number of Swahili varieties spread between Zanzibar, , the Congo, Burundi and , does not claim to provide an exhaustive classification of varieties, lects or practices. Instead, it modestly aims at providing a concise (yet not ultimate) overview of scholarly work in the fields of variation(ist) linguistics and dialectology on Swahili varieties, and attempts to change the predominant perspective: while the East African Coast has been the center of scholarly attention in most works, it is particularly the periphery that is the central arena for contact, change and patterns of variation in the present volume, explored through new approaches that expand the common methodology. Based on the editors’ research in DR Congo, Uganda, around , and in various urban settings in East Africa, a redirected focus may also be of potential interest for those already acquainted with the common and reliable standard works (such as Nurse & Hinnebusch 1993, and others). Methodologically, two current approaches are of central interest here, combining microvariation studies and practice-based sociolinguistics (see Sections 4.1-4.2).

2. On the spread and diversification of Swahili While the waves of diffusion along the coast and from the coast to the interior are well known due to archeological and historical sources on early contacts and expansions, as well as historical linguistic data, the spread of Swahili within the Congo basin and towards its current periphery (northwestern Uganda, northeastern , etc.) is only poorly documented. A sketchy overview of the diffusion of the language and current issues of classification and

3 NICO NASSENSTEIN & DAISUKE SHINAGAWA

diversification are thus needed in order to clarify the state of the art and the great need for scholarly work in order to fill the remaining gaps.

2.1 From the coast to the interior: Diffusion and classification of coastal dialects Among the coastal population, a linguistic predecessor of today’s Swahili was widely in use over a long period of time, “using an early form of Swahili […] tentatively attributed to its earliest period, that is, around 800” (Nurse & Hinnebusch 1993: 22), while the actual spread of the language along the coastline occurred much later 5 and early communities were mostly “spread thinly along the coast, from Somalia to at least Kilwa, possibly farther south” (ibid.).6 This continuum functioned on the basis of trade along the coast, while each coastal community was always also connected with inlanders (ibid.); the early networks were therefore never restricted only to the coast. While there was a common spread of innovations from urban areas to other urban areas and then to surrounding rural areas, (more recent) innovations in and shortly before the 19th century were diffused from areas south of the archipelago, explained by Nurse & Hinnebusch (1993: 31) with the increasing reputation and significance of Mombasa and Zanzibar, and a decreasing importance of Lamu. In the following, it was especially the “economic power of Zanzibar” that “carried its dialect Unguja out of its original domain, initially from the town into adjacent parts of Zanzibar island, later on to neighboring islands and along the adjacent coast, then upcountry as far as ” (ibid.). The European presences, in colonialism, through etc., and through the construction and consolidation of new urban centers along the coast (Dar es Salaam, Tanga, etc.), also contributed to the continuous spread of Kiunguja beyond its initial sphere of diffusion.

Coastal Swahili dialects, a continuum of a “1000-mile-long line of Swahili-speaking villages and towns […] between southern Somalia and northern ” (Nurse & Hinnebusch 1993: 29) were and are commonly grouped and listed as follows (according to different systems of classification), depending upon methodology, available sources and varieties included/excluded. While Nurse’s (1982) classification is based on phonological, lexical and morphological isoglosses, Nurse & Hinnebusch’s (1993) results are based on the

5 The different historical stages are listed by Nurse & Hinnebusch (1993: 21-23) as NEC, Sabaki, and then Swahili. While the oldest documents stem from around 1700 (ibid., referring to Miehe 1979, among others), the earliest assumption for PNEC (Proto-Northeast Coast Bantu) is approximately around 100 A.D., followed by PSA (Proto-Sabaki) maybe 500 years later, and then shortly after that already by PSW (Proto-Swahili). 6 While a detailed description of the historical movements and developments cannot be given here due to the limited scope of this , the focus will be on the early beginnings of a scholarly documentation of Swahili in the 19th century. This does not imply that knowledge transfer in Swahili society began with the European missionaries or later, with colonial agents.

Comparative Method and partially on lexicostatistics, while Möhlig’s (1995) work is based on dialectometrical analysis, and Maho’s (2009) most recent overview is based on Guthrie’s (1967–71) areal typology of the Bantu languages and his rough classification of Swahili, and constitutes an updated and adapted version. According to Maho’s “New updated list of the Bantu languages”, which can be regarded as the most recent and most extensive classification, Swahili is subclassified into a larger number of dialects and sociolects (G40 group).

7 The Mombasa dialects and Chifundi/Unguja are described by Nurse as “mixed” in terms of Northern vs. Southern features and are therefore not grouped with either of them. They are phonologically closer to the Southern Dialects, but in their verbal morphology are closer to the Northern Dialects. All other dialects are excluded from this list due to the scarcity of data.

However, apart from the core areas along the East African coast and throughout large parts of Tanzania and Kenya, Swahili has (as of today) spread as far as (northeastern DR Congo), Lubumbashi (southeastern DR Congo), northeastern Zambia, northern parts of Mozambique, and so forth (see Map 1, which gives an estimated maximal extension of the language).

10 All languages/varieties marked with asterisk are (probably) extinct.

Map 1: The maximal extension of Swahili (based on the authors’ knowledge)

There is a general problem in our understanding of how Swahili is diffused/used in Uganda, Burundi, and Rwanda. Labeled a “dilemma” (of being implemented in the constitution yet not practically used in most parts of the country) by Pawliková-Vilhanová (1996), this hints toward a large discrepancy in parameters of official/governmental and speakers’ actual knowledge and everyday use. In Uganda, Swahili is still considered the language of the army, of security guards, policemen etc., stigmatized and often viewed with negative language attitudes; and is only spoken by a significant part of the population in the northwestern West Nile region in the border triangle with DR Congo and , by remnant speakers in Acholiland (Lorenz, this volume), and in parts of northeastern Karamoja region. Apart from being a professional jargon and being restricted to specific, mostly remote, areas, Swahili is the language of tourism to the national parks and the language of popular musicians used in songs by , Sheebah Karungi and others (see also Ssempuuma 2017). The Swahili described for Kampala (in specific settings) by Myers- Scotton (1979) and Miner (2002) reveals similar patterns of simplification and loss of morphology, as for instance found in Nairobi Swahili (Deen 2002, among other publications) or the Swahili used in West Nile region (Nassenstein 2017a). In multilingual rural communities in Central/Western Uganda in Bunyoro Kingdom (cf. Duran’s [1975] study for Kenya), Swahili apparently also plays an important role, especially around refugee

8 ON VARIATION IN SWAHILI: CURRENT APPROACHES, TRENDS AND DIRECTIONS

settlements and mixed communities of ethnic Acholi, Chopi, Banyoro and Baganda (Storch & Mietzner 2015).

In Rwanda and Burundi, the situation is quite different. In Rwanda, where Swahili has been the (fourth) official language since 2017, Swahili mostly fulfills a symbolic function. However, in the western parts around Gisenyi it is used in cross-border trade with neighboring Goma, DR Congo, predominantly by refugees, policemen, traders and in bus parks, and so forth, whereas in Kigali, Swahili seems to be mostly restricted to the vibrant multicultural neighborhood of Nyamirambo, south of the capital. Only a few publications have dealt with the diffusion of Swahili and its parameters of use in Rwanda (among others, Karangwa 1995).

In Burundi, however, Swahili is widespread in urban areas, and is mostly used by the younger population, particularly in the music business and the cross-border trade with Tanzanians and Congolese. More detailed studies are presented by Der-Houssikian (2009), Belt (2010), and by Nassenstein (this volume). While Der-Houssikian, based on a limited corpus, describes Le Swahili de Bujumbura as a variety with stable (deviating) features, Nassenstein (this volume) considers it a fluid continuum that allows speakers to employ a broad variety of forms and structures from both Tanzanian and Congolese Swahili dialects.

It becomes evident that Swahili fulfills specific functions in urban contexts, even beyond the core areas from which it was diffused, the spread being caused by waves of migration, social change, and geopolitical parameters. Today we can thus witness the spread of Swahili to Juba (South Sudan) since the country’s independence, to (western DR Congo) since the overthrow of former dictator Mobutu in 1996 and with the rise of Kabila senior and Kabila junior as subsequent presidents (until 2019), and to Somalia, where it is also used by Al-Shabaab militia, whose origins lie either in Somalia or in the northern parts of Kenya. The following paragraphs will deal separately with Swahili as diffused in different areas of the DR Congo, and suggest an updated classification grounded in recent descriptive overviews.

2.2 Toward a classification of Swahili varieties at the western periphery Despite the solid documentation of coastal varieties and their relationships to each other in terms of shared innovations, isoglosses etc., the state of dialects on the western periphery (DR Congo, Rwanda, Burundi and parts of Uganda) is characterized by classificatory gaps and shortcomings. The available dialectological overviews and more fine-grained analyses of specific dialects have surely contributed to a better understanding of the broad diversity of morphological and syntactic variation in Swahili, but they have also left numerous questions

9 NICO NASSENSTEIN & DAISUKE SHINAGAWA

unanswered, and several areas neglected.11 The overview maps and lists of Swahili varieties illustrate this quite well, especially with regard to the widespread regiolects in today’s DR Congo, that have undergone processes of morphosyntactic restructuring which can be seen as a result of the diffusion of Swahili to the interior of the continent.

In some overviews the varieties diffused in Congo are completely left out (Nurse [1982: 165] explicitly states this), while in others they are subsumed under the label “(Ki)Ngwana”, which (at least today) functions mainly as an extrinsic label and is no longer used by speakers themselves when they refer to their varieties. 12 Historically, the term derived from the designation of its speakers, former slaves who were freed and constituted the main Swahili- speaking population of several former trade posts. They contributed to the spread of Swahili in different areas. Fabian (1986: 33) states that the label “Kingwana”, mostly applied to the northern regiolects of Swahili in the Congo, was presumably diffused after 1910 when it first appeared as “Kingwanya” in the literature, as used by Millman (1917). Goyvaerts (2007: 32) further notes that “[t] term Kingwana is never used. It would seem to be a notion that appears solely in the writings of westerners to refer, wrongly, to either ‘the Swahili of Congo Zaire’ (Harries 1955: 13) or ‘some sort of -like bad Swahili’ (Van den Eynde 1944: 6).” Early sources, such as translations of religious texts and parts of the Bible, often differentiate between “Ituri Kingwana” and “Lualaba Kingwana”, although the boundaries and differences between the two varieties are not made very clear in the available sources. While these labels were based on the areas where they were reportedly spoken, for example along the Ituri/Aruwimi and Lualaba rivers, respectively, Lualaba Kingwana actually represents today’s Kivu Swahili (or, according to Goyvaerts [2007], Bukavu Swahili), and Ituri Kingwana stands for Swahili further north. Both historical designations are also retained in a current overview of Swahili in the (2019).13 As indicated by the University of Hawai’i Press (1975: 677) in their bibliography of “Kingwana and other simplified forms”, the most exhaustive list of reference works for Congo Swahili14, Kingwana Swahili was “adopted as a lingua franca over what Deans (1953) calls half the Congo, in two sets of dialects – Lualaba in Kivu and the more pidginized Ituri in Oriental Province”. Deans (1953) points out that

11 This may have to do with demography, concepts of territoriality and also with the challenges to apply dialectological methods to highly multilingual mobile individuals in parts of the Congo, just to name a few. 12 Only in the case of Bunia Swahili, one can at times come across the language name Ituri Kingwana when speakers refer to the regiolect in Ituri, and then always in clear opposition to other more standardized varieties. 13 See https://glottolog.org/resource/languoid/id/cong1236 [last accessed on 15-07-2019]. 14 Another bibliography is provided by de Rooij (2005) as an online publication of the LPCA (Journal of Popular Culture in Africa), and another more extensive bibliography for Swahili in general is provided by Van Spaandonck (1965).

missionaries and linguists engaged in identifying and separating these two dialects in the 1930s and 1940s, acknowledging that Ituri Kingwana actually revealed more pidginized forms than Lualaba Kingwana. He also summarizes missionaries’ attempts at transforming these into a “Union Ngwana”, a unified and partly standardized variety especially used for the translation of the Bible, yet not spoken.

Few more detailed materials from colonial times are accessible and those that are are only helpful to a limited extent. Colonial descriptions of Congo Swahili varieties were mostly prescriptive and cannot be used as actual evidence for dialectal divergence, as they were mostly oriented at coastal varieties such as Kiunguja; among them are Hunter (1959), Whitehead & Whitehead (1928), and Les Frères Maristes (1952), to name but a few from different regions. Some others, especially lexical materials (Lenselaer 1983, Spinette 1960) and a collection of proverbs (Sabiti 1976), were closer to speakers’ actual realization than the before-mentioned sources. While Hunter (1959) and Whitehead & Whitehead (1928) focus on eastern/northeastern varieties, Les Frères Maristes (1952) deal with the variety from Kisangani. Lenselaer (1983) includes various dialects and Spinette’s short wordlist is based on entries collected in Ituri and Kisangani.

Apart from the (early) distinction between Lualaba Kingwana and Ituri Kingwana, recurrent in Bible translators’ works and prescriptive grammars from the 1920s onwards, the variety often described as Copperbelt Swahili, Shaba Swahili, or Lubumbashi Swahili, pejoratively also known as Potopoto Swahili (University of Hawai’i Press 1975, Fabian 1991), or later as Katanga Swahili, can be seen as the best studied variety spoken in the southeast of the country, and offers a different historical background for its emergence (for an overview, see Fabian 1986). Due to its partly descriptive rather than only prescriptive focus, being closer to the morphosyntactic properties of Congo Swahili than to ECS, the manual “Éléments de Kiswahili véhiculaire à l’usage des militaires de la base de Kamina” (compiled by de la Lindi [1938] for the Ministère de la Défense Nationale,) is worth mentioning; it sketches the use of this Swahili variety from the southeast for colonial soldiers by listing basic orders, requests, etc. Fabian (1986), however, offers a more extensive overview of early travelogues, wordlists and sketches than can be included here.

The confusion about dialectal/regiolectal differences and their localization on the map was surely also based on the fact that at the time of these overviews (1980s-1990s) the state of documentation was poor for most varieties, as it was only in the 1980s that Walter Schicho and Johannes Fabian began working on Shaba Swahili/Katanga Swahili/Lubumbashi Swahili in the southeast of former Zaire, and that Goyvaerts (1986, 2007), Wilt (1988) and Kaji (1982, 1985, 1992) began their descriptive work on the variety from the Kivu provinces (Kivu Swahili; labeled Bukavu Swahili by Goyvaerts). Today’s scarcity of more detailed studies, however, can be partially explained with the political situation and prevalent insecurity in parts of Eastern DR Congo, and to some extent with the challenges of drawing clear boundaries between the

11 NICO NASSENSTEIN & DAISUKE SHINAGAWA

varieties or establishing isoglosses. Speakers’ extensive migration, either based on trade or forced, due to conflict, as well as the rural exodus, have contributed to fluid boundaries between these varieties and to larger convergence areas. Moreover, in most areas, Swahili is speakers’ second, third, or fourth language, with considerable influence from other languages.

In Nurse & Hinnebusch’s (1993) extensive study, Congo Swahili varieties are only marginally dealt with, while in other dialectological overviews a considerable degree of confusion is caused by inadequate cartographic localizations or glossonyms, as in Möhlig (1995: 44-45), who lists only Ngwana, which he locates around today’s Lubumbashi (Katanga), while not indicating any Swahili variety for the areas further north (Kivus, Ituri, etc.). Maho (2009) differentiates between “Shaba Swahili/Katanga Swahili/Lubumbashi Swahili (G40F)” and “Ngwana/Kingwana/Congo Swahili (G40G)”. While Shaba Swahili is correctly marked on the map, the latter is placed a bit further north, adjacent to Lake , which actually does not correspond with the areas where either Kivu Swahili, Bunia Swahili or Kisangani Swahili is spoken. Another problem generally consists in assuming an apparent unity or homogeneity across varieties of Congo Swahili. While most colleagues generally do not distinguish different varieties or regiolects, others make modest distinctions: Goyvaerts (2007) differentiates, for instance, between the language of his study, Bukavu Swahili (in the present classification subsumed under Kivu Swahili), and Lubumbashi Swahili, as the two most dominant or widespread varieties, but leaves out others, presumably due to a lack of adequate accessible data. In most studies, Kisangani Swahili, spoken at the northwestern utmost periphery of Congo Swahili, is entirely left out, presumably due to its emergence as urban contact language in a convergence zone of Swahili and , which therefore receives less recognition as a separate dialect, especially due to the incorporation of some forms that look more like Bunia Swahili and others that look more like Kivu Swahili, due to the speakers’ steady contact with the different urban centers. However, its morphosyntactic and lexical features mark it clearly as distinctive variety. From the 1970s on, however, as predecessors to current studies, a few descriptive papers were written (Rzewuski 1974, Gilman 1970, 1979, Machozi 1989).

Three of the four varieties, namely Kivu Swahili, Kisangani Swahili and Lubumbashi Swahili, share a range of morphosyntactic patterns and also reveal somewhat similar inventories. The fourth variety, Bunia Swahili/Ituri Kingwana, is, however, both morphologically different and deviates lexically and phonologically from these other Congo Swahili varieties. Morphological evidence clearly shows patterns replicated from non-Bantu languages such as the Central Sudanic Ngiti, Lendu and so forth (see also Nassenstein & Dimmendaal 2020), affecting (optional) plural marking (Nassenstein 2017b) and other characteristics. Certain peculiarities in phonology (that are recurrent in all other Congo Swahili varieties) and also lexical retentions that are not “reintroductions” (Shinagawa, this volume) based on language contact, reveal, however, that Bunia Swahili seems to be

12 ON VARIATION IN SWAHILI: CURRENT APPROACHES, TRENDS AND DIRECTIONS

somewhat closer to coastal varieties in this regard (see also Deans 1953 for a similar observation). This makes a reconsideration of the widely accepted entry ports of Swahili into the Congo basin necessary. Apart from the well-described entry across Lake Tanganyika, as well as to the north and south of the lake (Goyvaerts 1986, Fabian 1986), and the introduction of Swahili by Belgian authorities in Shaba/Katanga, many sources (Stigand 1968/1923, Czekanowski 1924, Southall 1954, among others) point to a potential historical contact of local (Alur, and other) communities with Swahili speakers northeastwards and eastwards of Lake Albert, for instance due to existing trade networks. This makes an introduction of Swahili to Ituri thinkable, beyond the common view of Swahili having been introduced to Ituri as a result of early scattered slave traders’ posts and of Stanley’s Emin Pasha Relief Expedition (1886-1889) along the Aruwimi/Ituri river, which included Swahili-speaking Zanzibari and Manyema troops.

While sufficient linguistic evidence contributes to a more thorough understanding of variation along the coast (as based on Möhlig 1995, for instance), over the past decades there have been few data available for the varieties in the interior parts of the country. Hitherto, no study has analyzed phonological/lexical isoglosses, or, as a potentially more promising approach, pursued patterns of parametric variation (see Section 4.2); however, more recent studies of the different Swahili regiolects used in DR Congo have focused on lexicon and morphosyntax, and to a minor extent also on (the admittedly similar) phonology. Morphosyntactic variation is described for Kisangani Swahili by Nassenstein (2015), for Kivu Swahili by Nassenstein & Bose (2016), for Lubumbashi/Katanga Swahili by Ferrari et al. (2014)15, and in some overview articles for Bunia Swahili/Ituri Kingwana (Nassenstein 2017b, Nassenstein & Dimmendaal 2020). The results of these dialectal studies lead to a suggested fourfold classification of Congo Swahili, or Western Swahili, as also indicated in Map (2):

Figure 5: Western Swahili

Kivu Swahili (historically Lualaba Kingwana; also known as Bukavu/Goma Swahili) Bunia Swahili/Ituri Kingwana (its historical name, sometimes shortened to Kingwana) Kisangani Swahili (an urban contact variety from Kisangani and the surrounding areas) Lubumbashi Swahili/Katanga Swahili (historically Shaba Swahili/Copperbelt Swahili)

15 Numerous studies are available for this variety and far from all of them are mentioned here; early sketches by Polomé (1969) and Schicho (1980) were followed in more recent years especially by Fabian (1986), Schicho (1982), Kapanga (1993), De Roij (1996) and Ferrari et al. (2014).

Other, less distinctive contact varieties and contact zones, such as Bujumbura (Nassenstein, this volume), West Nile (Nassenstein 2017a) and Swahili as used in Rwanda are not included in the map. It is debatable whether they can be seen as separate dialects/regiolects.16

Map 2: Congo Swahili dialects and their approximate extension

Equally, sociolects based on these Congo Swahili varieties require a more profound analysis, as they are widely un(der)studied. There are very few available studies on youth registers from the Congo. Goyvaerts’ (1988, 1996) papers on the youth and secret language phenomena Indoubil and Kibalele from Bukavu (), an unpublished manuscript by Kutsch Lojenga (2009) on Kilungunya, a play language or ludling from Bunia (Ituri), a few papers on the youth language Yabacrâne from Goma () by Nassenstein (2016) and

16 It has to be noted that throughout the Western Swahili sphere, specific communities, especially of Muslim faith, use more standardized or more coastal-sounding Swahili, which is often classified as “Swahili bora” by their direct neighbors. This has mostly historical reasons. Some of these areas are towns and cities in Province, as well as along the northern shores of Lake Tanganyika (Uvira, Fizi, and southward to ).

Bose (2018), as well as Mulumbwa's (2009) study on Kindubile youth language from Lubumbashi (Katanga) are modest steps into this direction. These varieties will be further dealt with in Section 2.3.

2.3 Emerging registers and simplified varieties As part of the broad diversification of Swahili (Blommaert 1990), also emerging sociolects, youth registers/practices and simplified contact dialects need to be taken into consideration. Apart from the dialects that are listed in the dialectological overview maps, Maho (2009) also lists the Swahili-based youth language practices Sheng and , first attested in the Kenyan capital Nairobi. While Sheng quickly expanded and became a language of wider communication beyond Nairobi as well, Engsh is English-based and remains more restricted to the capital (Barasa & Mous 2017). According to Maho’s (re)classification, Sheng receives the letter-digit combination G40E and Engsh G40D. Apart from the well-studied Sheng, for which there are several extensive descriptive, sociolinguistic and ethnographic studies (for instance Rudd 2008, Ferrari 2009, Samper 2002, Wairungu 2014, Githiora 2019; see also Shinagawa, this volume) and its lesser known equivalent Engsh, other sociolects are also included by Maho (2009: 96-97), who further lists Asian Swahili/Kibabu (G40A), Cutchi Swahili (G40B), Kisetla/Settla/Settler Swahili (G40C), and KiKAR/Kikeya (G40H). While some of these are well-described, others are not treated in studies, and evidence for their use is actually rare. Moreover, Maho’s list is not exhaustive. In terms of youth language practices or youth registers based on Swahili, Goyvaerts (1996) provided a short description of Kibalele, a slang predominantly used by criminals in Bukavu (South Kivu, DR Congo), and of Indoubil, a youth language also diffused in Bukavu, the largest urban center in the area. In Goma (North Kivu, DR Congo), the youth language Yabacrâne (sometimes also labeled Yakicrâne, sometimes not attributed with a specific label at all) is reportedly used by young gang members, sportsmen and others (Bose 2018).

This random list surely does not cover all emergent linguistic practices that are used by speakers and is also problematic due to the mixture of (geographically distributed) dialects undoubtedly separated by isoglosses, with sociolinguistic practices whose communities of speakers and areas of diffusion can hardly be limited (see also Section 4.2 for a practice-based approach to variation). Very often these are rather context-based registers that function on the basis of processes of “enregisterment” of speakers associating the register in question with specific social images and groups.

The pidginization and to a lesser extent creolization17 of Swahili varieties has been at the center of academic attention, with a range of studies that describe early contact dialects and their simplified structure and functional use. The following simplified varieties and practices are recurrent in the literature:

Apart from these sources and some songs that can be found on YouTube, no linguistic study was available. On the first of the indicated websites, it is described as follows: “This Jangbari dialect evolved as a result of the situation then, a total blend of Kutchi Khoja ancestry, the influence of Zanzibar's Waswahili and their Swahili and the vernacular of the school being Gujarati. It originated way back from the nineteenth century” [last accessed on 15-07-2019].

Swahili/Ituri Kingwana, Kisangani Swahili, etc.), they are not listed here due to the focus on contact phenomena and the broader regional context (as one of a range of Eastern Congo regiolects) in these studies (see Section 2.2).

3. Established approaches to Swahili varieties with a longer tradition Since Krapf’s early missionary work in the mid-1850s, more than one and a half centuries of Swahili scholarship have yielded a range of approaches to the study of variation in Swahili, either focusing on descriptive work, on dialectometrical analyses, lexicostatistics, and more recently on methodological approaches such as parametric variation and practice-based sociolinguistics. In the following, we aim to sketch some of the key methodological approaches to variation in Swahili that are recurrent frameworks in numerous studies.

3.1 Early descriptive studies Early descriptive grammars were often compiled by missionaries and focused on the more prestigious coastal varieties, before Swahili was standardized and implemented as major lingua franca during colonial rule. The main competing varieties that were described in early grammars were Kiunguja from Zanzibar, as studied by Steere (1870) in his handbook, and other competing varieties such as Kimrima and Kimvita. Krapf, a missionary from the Church Missionary Society, translated the Bible into the Kimvita dialect of Mombasa, compiled a grammatical description with Rebmann (1850) and later published a dictionary (1882). While Sacleux (1909) was well acquainted with all these sources, he dealt with ten dialects in his study, among them what is often labeled as Kimrima, a coastal dialect of northern Tanzania (a term that is rejected by Nurse & Hinnebusch (1993: 11) as it is a geographical designation); he favored and promoted Kiunguja, however. Stigand (1915) deals with various dialects and offers very short overview sketches, some of varieties which are no longer or only marginally spoken. The rather prescriptive colonial studies of Congo Swahili/Western Swahili varieties have already been mentioned (Section 2.3) and will not be repeated here; especially due to the fact that their focus is in most cases not a descriptive linguistic one.

Among the most cited descriptions of Kiunguja are Polomé (1967) and Ashton (1944); despite their non-canonical structure they still range among the overview studies that are considered as state of the art (to some extent). Schadeberg’s (1992) short sketch, Mohamed’s (2001) pedagogical grammar and Mpiranya’s (2015) learner’s grammar also range among the works represented on the bookshelves of most Africanists, partly didactic, partly descriptive, yet all dealing with Kiunguja. Bakari (1985) presents an overview study of Kenyan Swahili dialects, with a focus on morphological variation, and Racine-Issa (2002) offers a detailed description of the Kikae dialect from Zanzibar. More recent descriptive studies deal with urban dialects, such as a short sketch of Nairobi Swahili in Deen’s (2005) work on acquisition,

17 NICO NASSENSTEIN & DAISUKE SHINAGAWA

and sketches of Bukavu Swahili (Wilt 1988, already mentioned in Section 2.2) and Lubumbashi Swahili (Ferrari et al. 2014), just to mention a few. While the genre of descriptive grammars for specific dialects has not become obsolete, it has, with the growing body of scholarly literature, given way to other methodological approaches and analyses, as will be sketched in the following.

3.2 Dialectology/Dialectrometry The scholarly interest in dialectal differences in Swahili, especially along the East African coast, has led to a range of studies with a dialectometrical focus since the 1980s (among them, predominantly Möhlig & Winter 1980, Möhlig 1983, Möhlig 1984/85, Möhlig 1986, and Möhlig 1995 explicitly for Swahili dialects); in this approach, phonological isoglosses, lexical items and also morphological forms can be compared and their relationship can be analyzed. Möhlig (1986: 56), in a study of from the coast, including major Swahili dialects (among them Tikuu, Siyu, Pate, Amu, Mvita, Chirasi, Vumba, Pemba, Makunduchi and Mwani – dialect names as listed by the author), explains the levels of dialectometrical analysis as threefold, consisting of a purely linguistic lexical dialectometry, a lexical dialectometry of geographical qualification, and phonological dialectometry. Methodologically, in dialectometrical studies both the number of differentiating features between varieties is important but also the weighting of these isoglosses and the frequency with which certain features occur (see also Dimmendaal [2011: 164-167] for a concise overview). In general, a list of lexical items numbering between 100 and 633 is chosen, adapted to African languages in terms of the core and more specific cultural vocabulary that are included. The ratings start from 30 (absolute identity), with 20 (partial phonological divergence) for shared roots but for instance phonological and morphological divergence, while 0 is the value rating when the root is a different one (ibid.: 165). After several more steps, the calculation eventually reveals the difference between dialects based on the observed isoglosses (see, for instance, Figure 7 for some northern Swahili dialects, taken from Möhlig 1995) and can also be presented diagrammatically, with the connecting lines between dialects being of different strengths; bold lines show dialects that are closer to each other. Möhlig (1995: 58) lists the lexical dialectometrical relations between the Northern Swahili dialects as follows, with Amu as the first (formerly influential) dialect and showing its relationship with the surrounding dialects (see below).

Full’s (2006) dialectometrical analysis of Comorian languages has contributed to more recent dialectological insights into Swahili (and neighboring languages). Due to the relatively high amount of data and a lack of diachronic information, dialectometry is less often applied today. However, more recent papers have rediscovered an interest in dialectology, yet with a different direction. Githinji & Njoroge’s (2017) analysis of speakers’ perceptions (for the framework, see Preston 1999) makes a contribution to the field of perceptual dialectology and how speakers’ attitudes toward varieties and their ideologies concerning their own language(s) affect their localization of other speakers.

3.3 Lexicostatistics21 In their influential study, Nurse & Hinnebusch (1993) argue that “phonological criteria do not always provide a conclusive analysis of the classification and development of a set of closely related languages”; apart from the Comparative Method, alternative solutions can be obtained through lexicostatistics, according to the latter. Based on this method, one is able to “attempt to assemble a total picture in the different linguistic changes that have taken place in the evolution of the Sabaki languages” (ibid.: 24). Swadesh (1952, etc.) initially developed the method, first targeting languages with a long written history in order to determine when and which languages split off from other related languages, and how many retentions in basic vocabulary could be attested over time. The general assumption in this approach is that changes in the vocabulary occur in languages at approximately the same pace. For the Swadesh wordlist of 100/200 entries, a rate of retention of around 86% over the course of 1000 years is assumed. With a specific algorithm, Swadesh then calculated the time of vocabulary loss (see Dimmendaal 2011: 71-74).

Heine (1973), Nurse & Phillipson (1980), Hinnebusch (1981, with a lexicostatistical and phonological focus), Nurse & Hinnebusch (1993, with different approaches combined), Hinnebusch (1999) and Nurse (1999, with reference to different Bantu subgroups in East Africa) have then extensively applied statistical methods to Sabaki/Swahili and the classification of East African Bantu languages. In their often-cited framework, Nurse &

21 Our focus here lies on lexicostatistical methods; we will not deal with the broader (and to some extent encompassing) “comparative method” in a separate subsection. The comparative method looks back on a longer tradition and encompasses a wide range of methods and principles, having emerged in the study of Indo-European languages, and involving “the establishment of lexical and grammatical cognates, the reconstruction of their historical development, techniques for the subclassification of related languages, and the use of language-internal evidence, more specifically the application of so-called ‘internal reconstruction’” (Dimmendaal 2011: 1). This chapter does not intend to introduce general notions of historical-comparative linguistics, based on the intention of working out genetic relationships between languages and reconstructing earlier stages, but rather focuses on lexicostatistics as one of the major strands in the study of Swahili.

Hinnebusch (1993) differentiate, based on their results, between ND1 (the Northern Dialects Mwiini, Tikuu, Siu, Pate, Amu, (Malindi), the Mombasa dialects and potentially also Chifundi), ND2 (Mwiini, Tikuu, Siu, Pate, Amu), ND3 (Tikuu, Siu, Pate, Amu) and SD (the Southern Dialects Vumba, Mtang’ata, Pemba, Tumbatu, Makunduchi, [Unguja], Mafia, [Kilwa?] and [Mgao?]).22 Hinnebusch (1996: 78) summarizes thus:

[W]hile the ND set stands out lexicostatistically, the SD set does not. Lexicostatistically Swahili consists of a core cluster of ND dialects with the others chained incrementally to the core in a typical continuum. Thus, it is only ND that is positively subgrouped while SD is not, although parts of SD do subgroup, e.g., Pemba, Tumbatu, Makunduchi, and Unguja.

The following overview is adapted from Hinnebusch (1996: 76-77) and summarizes Nurse & Hinnebusch’s (1993) internal Sabaki averages in order to see how “Sabaki” Swahili actually is (Figure 8); and also how cohesive some of the Swahili dialects are with regard to others (Figure 9).

Figure 8: Sabaki internal averages (Hinnebusch 1996: 76)

Comorian 81% Mijikenda 73% Pokomo 73% Swahili 74%

Figure 9: Swahili internal averages

ND (Am, Pa, Si, Ti) 89% ND + Mombasa area 82% SD (Ung, , Vu, etc.) 72% Zanzibar and Pemba dialects 72%

22 Nurse & Hinnebusch (1993) come to the conclusion that ND1 has good support, especially phonologically and morphologically, which lets them establish a Proto-ND1, positing a ND1 area around the Lamu archipelago in the 9th century, and also assuming early contact with Dahalo (p. 507). For ND2, they list a range of phonological innovations that occurred after the split from ancestral Mvita and define it as a solid grouping (p. 508). ND2 further reveals some innovations that are also shared by Comorian. For the ND3 group, they state that phonological and morphological innovations are clear and more significant than the lexicostatistical data, which cannot be doubted, but may also result from lexical convergence. They further observe that there is a contradiction in SD, with no clear lexicostatistical unity or lexical evidence but certain conservative phonological features and some recurrent tense-aspect innovations that are common across SD and that hint toward a Proto-SD (p. 512).

This shows that the “Swahili dialect continuum is as cohesive lexically as the Pokomo dialect chain or as the Mijikenda cluster of dialects, but not as cohesive as Comorian”, and also that Northern Dialects are more cohesive than Southern Dialects. This is due to the different histories of specific dialects; some of the Swahili internal averages (ND) further reveal similar rates to Sabaki groupings such as Comorian in Figure 8 (for a more detailed overview, see also Hinnebusch [1999: 204], providing a “Sabaki lexicostatistical table”).

Nurse (1999: 5) further summarizes for NEC (North-East-Coast) that the findings mark it as a solid grouping, while, “[g]iven this geographical and linguistic spread, and the two millenia since the protolanguage, there is considerable divergence, especially at its edges”. He further discusses the methodological challenge of whether to include closely-related languages along the Mozambican coast, for example Mwani (see Schadeberg 1995, among others). Another issue raised by Nurse (1999: 7) is the fact that the proto-period was probably very brief and did not allow for numerous lexical/non-lexical innovations (see also Nurse & Hinnebusch 1993: 288-289), while the following 2000-year period led to a high degree of divergence.

4. Predominant approaches to variation in this volume Apart from general descriptions of peripheral varieties and salient patterns of variation in contact situations, two major strands are represented in this volume, namely the approach to the diversity of Swahili varieties and contact settings through the study of microvariation, and a more interdisciplinary sociolinguistic approach to variation that understands language as social practice, performed in communities of practice, alongside other social practices (Eckert 2000).

4.1 Microvariation One of the two guiding methodologies of this work is the so-called microvariation studies, which may be defined as linguistic investigations into structural variation among languages closely related in terms of genetics and/or geographical distribution by means of typologically micro-level parameters.23 It primarily aims to describe such structural diversity and to clarify

23 As suggested here, the term “microvariation” may implicate two different facets of the framework (thus it can be understood in two different ways). One is about the scope of investigation, i.e., sample languages are restricted to those genetically and geographically closely related, and the other is about the granularity of parameters, i.e. they are more detailed, fine-grained, and specific to the structural features of languages investigated than those used in general macro-typology. Not only in the context of descriptive/typological study but also in formalistic/theoretical study (cf. Barbiers 2009, Brandner 2012 etc.), the general usage of the

21 NICO NASSENSTEIN & DAISUKE SHINAGAWA

typological principles that explain the intra-genetic or areal typological diversity that may not be covered by large-scale sampling typology (see Daniel 2011). Based on data obtained through consistent and fine-grained parameters designated to capture structural microvariation found in target languages, this framework also helps us approach issues regarding: i) extremes of structural complexity exhibited by the target languages, ii) possible ranges of structural diversity observed in genetically related languages, and iii) diverging and converging mechanisms of language change due to both inter- and intra-genetic language contact.24

While pilot attempts at microvariation study were made in regional varieties of European languages such as Dutch (Barbiers et al. 2005) and Italo-Romance languages (Benincà & Poletto 2007), the first application of this framework to Bantu languages was made by Marten et al. (2007). 25 In order to capture the morphosyntactic micro-typological variation in a systematic way, they set up 19 parameters regarding verbal morphology (object marking strategies etc.) and syntactic features in specific constructions (double object, relative, locative inversion, conjoint/disjoint, etc.), and provide future perspectives on the study of Bantu microvariation. Following this seminal paper, current studies have further developed a more fine-grained parameter set consisting of 142 micro-parameters covering a broad range of morphosyntactic components (Guérois et al. 2017, then also adapted by Shinagawa & Abe 2019 in a recent study of a range of East African Bantu languages). As summarized in Section 5, several papers in this volume adopt this framework for the analysis of different varieties.

4.2 Practice-based sociolinguistics The second method is based on current approaches in sociolinguistics and focuses on performance, style and practice in the interactions of Swahili speakers. Beyond established and more traditional approaches to the social context of language use, for example by shedding light on social variables and social networks and studying Swahili “sociolects” as demarcated varieties (such as Kisetla, Sheng, or Yabacrâne), a redefined approach targets speakers’ linguistic and extralinguistic practices as part of a broader performance within a community of practice (CoP) (a term initially introduced by Lave & Wenger 1991). A

term tends to point at the former concept, especially when it is mentioned in relation to intra-genetic typology or areal typology. However, it should be stressed that our intention of adopting the framework of microvariation study is significantly motivated by the latter concept as well. 24 One of the main aims of a leading project in Bantu microvariation study, “Morphological variation in Bantu: Typology, contact and change” (PI. Lutz Marten, hosted at SOAS, 2014-2018) was exactly this point. 25 It is important to note that there have been pioneering works of cross-Bantu linguistic survey carried out, for example, by Bantuist linguists based in Tervuren (e.g. Bastin 1983), which may be characterized as “item- based” research (in that most of the parameters are set up to check the presence or absence of a specific element, etc.).

22 ON VARIATION IN SWAHILI: CURRENT APPROACHES, TRENDS AND DIRECTIONS

different understanding of sociolinguistic practices includes the analysis of linguistic stylization and means acknowledging individuals’ fluid language use beyond stable “codes”, which becomes more obviously significant when looking at some of the above-listed youth language practices in the Swahili-speaking areas (Section 2.3). These should be understood as registers, or as “styles” of speaking and performing Swahili, rather than considering them as countable or classified varieties (which, as a critique of Maho’s 2009 updated list, suggests that we should not incorporate these as “‘new’ languages in the Bantu area”; (Maho 2009: 96-97).

A turn toward a more practice-oriented sociolinguistics, which in the field of sociolinguistics is no longer a novelty, although it is certainly not the most applied method in the field of Swahili, can be related to Eckert’s (2012) ‘three waves of variation study’.

While the ‘first wave’, according to Eckert, constituted a classic approach to sociolinguistic variation, through the analysis of social parameters such as age, gender, social class etc., the ‘second wave’ focused on an ethnographic approach, through the “attribution of social agency” to the varieties of language among certain groups as expressive means of a “local or class identity” (ibid.: 91). The third wave, finally, focuses on stylistic issues rather than on static concepts of social parameters or categories (like age, gender, etc.) as the major triggers for variation (first wave), or on the static concept of networks of speakers and group affiliation (second wave). The third wave thus focuses on the “reflection of social identities and categories to the linguistic practice” (ibid.: 94), where speakers position themselves in certain spaces of society through means of stylistic linguistic practices.

This also implies a focus on the fluid nature of language, performances, speakers’ social lives and practices, whereby the idea of discrete “language systems” seems to be outdated, particularly in terms of sociolinguistic contexts. In terms of the linguistic practices of East African youths (for an overview and a first seminal paper, see Kießling & Mous 2004), this has been methodologically implemented for instance by scholars who study poetic texts in their context (Samper 2002, Ferrari 2004, 2006, Vierke 2015) and who analyze poetic aspects of Sheng in their contextual practices, as well as in an early study by Abdulaziz & Osinde (1997), who collected anecdotes. Literary texts, subsuming reading, writing and narrated stories within youths’ social practices, also have to be included; see for instance Maillu (1989), Shinagawa (2006), and others. Other studies focus on practice through participant observation, as suggested by Beyer (2015) and as carried out by Wairungu (2014). More holistic approaches to speakers’ practices are also promoted by Beck (2015: 55-57) in her study of Sheng; she emphasizes that all kinds of text need to be included and considers language as a “fluid knowledge sediment with particular routines attached to it that is incrementally operationalized, invoked and put to use in a particular situation”. In more general sociolinguistic scholarly work, numerous examples for this turn could be cited; instead, we will turn to look at the contexts that are dealt with in the present volume, offering a broader perspective on specific practices.

23 NICO NASSENSTEIN & DAISUKE SHINAGAWA

Some of the papers in this issue treat Swahili as fluid linguistic practice, for instance as part of a heteroglossic repertoire of Ugandan speakers and their multilingual practices; as a highly contextual practice that depends upon the situational context of speech and its pragmatic aspects, as in the case of Burundian speakers and the variability of their Swahili; in terms of fluid (trans)languaging among multilingual Tanzanian speakers; and as a very common and everyday register variation among speakers of Kivu Swahili in the Congo. This frames the understanding of language varieties as “ways of speaking”, rooted deeply in Hymes’ (1974) work on the ethnography of communication and also found in linguistic anthropology and (interactional) sociolinguistics alike, where apart from the study of the grammatical foundations, the study of linguistic styles becomes essential, researched by means of ethnographic methods. Processes of “enregisterment” (Agha 2003) and the indexical value of language (Silverstein 1993) also need to be included in the analysis here, when focusing on the shift from fixed social variables and demarcated sociolects toward fluid practice, stylization, its motivations and social meaning.

5. About this volume The papers contributed to this issue vary in terms of the varieties they deal with as well as frameworks on which they are based. Regarding varieties, we can categorize them into four, namely i) Coastal varieties, including various forms of Zanzibar Swahili and the rarely described north coast variety Chimiini, ii) Sheng as an urban contact variety, iii) “Old Swahili” as a diachronic variety (or a succession of varieties), and iv) Inland or “upcountry” varieties strongly affected by language contact, including Swahili in the southern rural areas of Tanzania, as well as Congolese Swahili, Swahili in Northern Uganda and in the Burundian capital Bujumbura. In the following, we provide a brief overview of each paper.

Miyazaki and Takemura show dialectal microvariation in Zanzibar Swahili, ranging from lexical to morphosyntactic aspects, with empirical data collected through their fieldwork. Based on this data, they cast doubt on the generally recognized dialectal classification, which basically relies on geographical proximity, and thus propose a combined approach consisting of traditional description and micro-typological analysis to capture a more precise picture of typological features of Zanzibar varieties and their classification.

Primarily comparing the two Zanzibar varieties, Kimakunduchi and Kiunguja, Furumoto proposes a novel understanding of the historical development of the aspectual prefix -me-, found in both varieties but with different (yet related) functions. One of the striking proposals he makes is that the marker -me- found in a number of Swahili dialects has developed from perfect to perfective, reflecting a cross-linguistically widespread path of change. Support for this analysis of the historical development can also be seen in data from another southern dialect, Kitumbatu, in which the cognate prefix -ma- is found.

In their overview paper, Mumin and Dimmendaal provide a sketch of Chimiini, originally spoken in southern Somalia (Brava), and nowadays mostly diffused in adjacent Kenya and the diaspora. In their concise study, the authors summarize the most salient phonological and morphological properties of the language as well as patterns of variation among speakers, based on an extensive data corpus. Apart from morphophonological features, they discuss how the language also served as a marker of stigmatization and exclusion in Somalia, and how the community was marginalized. Emblematic features that indexically refer to social categories such as clans and lineages are also included in the analysis.

There are two papers dealing with the urban contact variety Sheng, which is said to have emerged in Nairobi as early as the 1970s and is currently spreading across generational and geographical boundaries. In his paper titled “Syntactic distribution of relativizers and the development of -enye RC in Sheng”, Shinagawa attempts to clarify the unique distribution pattern of relative clause constructions in Sheng. He further investigates the use of -enye ‘having’ as a relativizer, one of the common features shared with other inland varieties but not with the “standard” variety, and proposes a distributional scale of -enye which explains how this element may have developed across the varieties from a structural point of view.

Investigating diverse varieties, ranging from diachronic ones (“Old Swahili”) to contemporary ones including Sheng, Gibson, Mapunda, Marten, Shah and Taji explore the morphosyntactic microvariation of object marking from a micro-typological approach. Based on an overview of object marking with reference to the cross-Bantu database of morphosyntactic microvariation (Marten et al. 2018), they focus on non-canonical structures (as distinct from those with a single pre-stem object maker), namely emphatic object doubling in Old Swahili, double object marking in Sheng, and the verb-final enclitic -ni as (part of) 2nd person plural marking, etc., and discuss their historical and typological relationships.

Regarding the inland varieties and the process of expansion and contact with indigenous (mostly Bantu) languages, we have five papers in this issue. Kaji investigates how Swahili expanded far into eastern Congo, especially considering the structural properties of languages involved in the process. His main point of discussion is that the linguistic influences between Swahili and indigenous languages are not unidirectional from the former to the latter but that the process of linguistic transfer should be regarded as bidirectional and that the structural (including lexical taxonomic) influence of indigenous languages on Swahili is by no means dismissible. He explains this point by showing linguistic parallels between one of the Congolese Swahili varieties spoken by the Tembo people, living on the western shore of , and their native language, Tembo (Bantu JD531).

Kutsukake and Yoneda also investigate the interrelationship between Swahili and indigenous languages spoken in rural parts of southern Tanzania, focusing on current situations of multilingual dynamism. Not only do they mention the process of localization of

25 NICO NASSENSTEIN & DAISUKE SHINAGAWA

Swahili (“ethnic-languagized Swahili” in their terms), they also describe “Swahilization” processes of indigenous languages based on their field recordings of natural conversation, consisting of different linguistic resources. Referring also to speakers’ self-awareness about the language they think they are using in a specific conversation, which can sometimes be mismatched with the main linguistic resource adopted in the same conversation, they propose that what happens in the speakers’ minds can be better described as “translanguaging” (cf. García & Wei 2014) rather than as simple (and conscious) code-switching; they argue that such a dynamic linguistic practice is actually rather positive for indigenous languages, as they are not considered to be completely distinct in rapidly changing multilingual settings in Africa.

In his contribution, Nassenstein sheds light on the variety of Swahili spoken in the urban setting of Bujumbura, the Burundian capital. Based on a brief sociohistorical overview of its emergence linked to German colonial times (when Germany ruled over what was formerly known as Ruanda-Urundi) and on a description of the most prominent divergent characteristics of this variety, he focuses on its variability. Depending upon the conversational setting and the interlocutors, a speaker adapts his patterns and also specific realizations of some TA markers and the copula either to a more Tanzanian-sounding or a more Congolese-sounding Swahili. This structural adaptability is, according to Nassenstein, based on a broad knowledge of different varieties of Swahili (in the Burundian corridor between the two other countries) and on matters of prestige and status (for example, knowing that the widespread habitual/imperfective aspectual marking -ak in pre-final position is reminiscent of Congo Swahili etc.). As a contribution to the study of urban contact varieties of Swahili in East Africa, the paper also includes the notion of “metrolingualism” (Pennycook & Otsuji 2015), with Bujumbura serving as an urban multilingual “playground” as a primary sociolinguistic prerequisite for language change and variation in Swahili.

Lorenz analyzes the sociolinguistics of Swahili and its use in multilingual speakers’ repertoires in Gulu, the urban center of Northern Uganda (Acholiland), introducing the subject by offering a brief historical overview of Swahili as used in Uganda. Based on partially quantitative analysis and sociolinguistic interviews, he analyzes the use of Swahili in Ugandans’ everyday language and compares the domains, context and frequency of Swahili with speakers’ L1 language, Acholi, as well as English, and others. Treated as part of the (often neglected) “periphery” of the Swahili-speaking world, the analysis of the language ecology of Gulu intends to answer the question of speakers’ (and non-speakers’) attitudes toward Swahili and the efficiency of further implementation and promotion of Swahili on a political level, seen from the angle of peripheral actors.

Bose describes and compares Kivu Swahili from a perspective of different “ways of speaking”, focusing on ethnicity and in-group cohesion. While Kivu Swahili is often described as an amalgamation of the city dialects spoken in Goma (North Kivu) and Bukavu (South Kivu, see also Goyvaerts 2007), the author stresses the variability of Kivu Swahili

when used by speakers from different ethnic backgrounds. Specific ethnicized realizations can be employed by speakers as community-building strategies but can equally be leveled or omitted (for example in case one’s specific variety of Swahili is regarded negatively or ridiculed), or can used mimetically in order to mock or ostracize people. The social functions of different realizations of Kivu Swahili question the apparent homogeneity claimed in numerous dialectal studies and show the broad variability of language, and especially the adaptability of speakers.

Pasch and Kumbatulu focus on lexical borrowings from Swahili recurrent in the Ubangian language Pazande, highlighting language contact scenarios between Bantu and non-Bantu languages in a convergence area of the northeastern Bantu borderlands. While several of the loanwords discussed are easy to trace, others have entered the language via the widespread vehicular languages Bangala and Lingala. The long-term presence of Swahili speakers from the time of the Arab-Zanzibari penetration into the Congo basin onwards shows how complex contact scenarios are, and that chains of lexical and grammatical borrowings function across other languages. Especially in an area such as the eastern CAR, the Uele Provinces of DR Congo and South Sudan, where was for a long time much more widespread than Swahili, the paper sheds new light on the role of Swahili in trade and migratory waves of individual speakers.

In her afterword, Miehe summarizes different perspectives on Swahili based on dominant directions in Swahili research during the 20th century and also presents an outlook on potential further directions in the study of the language and its varieties.

6. What we can gain from a new look at variation in Swahili: Outlook on further studies Despite its good state of documentation compared to other African languages and despite the fact that Swahili is the Sub-Saharan language with the highest number of speakers, a new special issue on linguistic variation is far from redundant. Apart from specific neglected areas and contact settings, the dominant methodological approaches sketched in this introductory paper still need to be rethought more radically.

What is repeatedly addressed in the papers contributed to this volume is that there are more diverse phenomena in currently spoken Swahili varieties than those reported in previous studies and that the diversification processes are vigorous and ongoing in many parts of the current – and still expanding – Swahili-speaking world. Contact phenomena between Swahili and other indigenous and/or socially prestigious European languages are regarded as bidirectional interactions and this dynamism brings constant fluidity to the grammatical

27 NICO NASSENSTEIN & DAISUKE SHINAGAWA

system of existent varieties, resulting in structural diversification, which provides a challenge for the future study of micro-parametric typology.

From a sociolinguistic viewpoint, language contact situations, which may even lead to the emergence of novel varieties, are usually motivated and driven by social factors such as migration, urbanization, border crossing, computer-mediated communication, etc. – often in relation to fluid “translanguaging” practices and based on communities of practice determined and (self-)defined by extralinguistic parameters as well. In these contexts, “style” plays a major role, in a theoretical turn that is often described as “third-wave sociolinguistics” (based on Eckert 2012), and no longer limited to Labov’s (1966) more static view of fixed social variables that induce a specific language behavior, nor to Milroy & Milroy’s (1985) understanding of variation as mainly dependent upon speakers’ social networks (see also Section 4.2). At times, especially in the context of youth language practices, these community transformations may then give birth to new “stylects” (cf. Hurst 2008, 2009), as a stylization of language going hand-in-hand with other community-constituting factors; a sort of (socio)linguistic change that deviates from models of straightforward language shift/change. The practice-based approach of sociolinguistics has been adopted in order to provide a better understanding of such dynamic multilingual settings, and the field of study within this framework will continue to expand as long as multilingual situations in the Swahili-speaking world continue to change so vibrantly.

Another field of further exploration is the description and documentation of less known or endangered varieties. As suggested in several papers in this volume, there remain a number of (possible) varieties whose socio/linguistic details are still unclear. Such languages include some small (and possibly historical) coastal dialects spoken in Zanzibar, as well as in islands further south, such as Comoros and Madagascar; varieties of “localized” Swahili that are still growing; and the ever developing urban varieties. These under-documented varieties should also be included in scholars’ future research agenda under the framework pursued by several authors represented in this volume. Apart from well-known dialects and the predictable outputs of contact settings, the “northern Bantu borderland” (Tucker & Bryan 1958/2017 is in particular need of recentering in further contact studies, where Bantu languages are in constant contact with non-Bantu languages and therefore reveal interesting and often understudied contact features (see also Kumbatulu & Pasch, this volume). This includes Swahili in contact with the Eastern Kakwa/Bari, Maa (Drolc 1999), with the Central Sudanic languages Lendu, Ngiti, Lugbara and others, with Western Nilotic speakers of Acholi, Alur and , and with those who communicate in (Juba) Arabic or Kinubi (Luffin 2014). Nurse & Hinnebusch (1993: 26) also mention early contact between Swahili/Sabaki varieties and non-Bantu languages, such as for instance between Elwana and Dahalo, Mwiini and Somali (see also the sketch of Chimwiini in this volume), as well as innovations in Comorian which can be explained due to contact with an old form of Malagasy.

28 ON VARIATION IN SWAHILI: CURRENT APPROACHES, TRENDS AND DIRECTIONS

While existing and well-known studies have focused on broader linguistic areas (Sprachbünde) across language phyla, such as for instance Heine & Kuteva (2005), a Swahili- centered focus on the northern Bantu borderlands could specifically focus on replication patterns found in (restructured) Swahili in Ituri (DR Congo) or West Nile (Uganda). Multilingual speakers’ broad repertoires often include both Bantu and non-Bantu languages, leading to idiolectal or dialectal realizations that no longer correspond with a narrower understanding of Bantu structure (see, for instance, Bunia Swahili/Ituri Kingwana and its lectal variation, Nassenstein & Dimmendaal 2020).26

Language and mobility, especially in an era of tremendous waves of migration within or adjacent to Swahili-speaking areas (from DR Congo and Burundi to Uganda and Rwanda, from South Sudan to Uganda, from Burundi to Tanzania, etc.), surely ranges among the most pressing topics in sociolinguistics. These complex settings are characterized by prevailing and often long-lasting violent conflicts that have a major impact on language ecology and speakers’ concrete language repertoires. Ruptures within and across communities, large numbers of IDP and regroupings of speakers in refugee camps or far from their original places of origin constantly impact on the Swahili(s) spoken by these mobile individuals. The ongoing conflict has for instance contributed to the spread of Kivu Swahili in Eastern DR Congo as far as Kisangani and into Ituri. Also, ethnic tensions as they occurred in Kenya in 2007 (and to a lesser extent also in subsequent years) leave their footprint in people’s speech behavior and their awareness with regard to “ethnic registers” of Swahili and Sheng (see, for instance, Kioko 2015 on this matter; see also Bose this volume) and need to be taken into consideration when linguistic variation is addressed.

Language and tourism, also located in the broader field of mobility, yet in contrast as a growing economic resource in East Africa, has moved into the focus of linguists’ attention more recently, and is still expanding as a topic in sociolinguistics and linguistic anthropology (for a more general study, see for instance Phipps 2007). A recent volume by Mietzner & Storch (2019) focuses on the Kenyan coast and on tourist-host interactions in philanthropic

26 While some of the structural deviations represent common processes of linguistic change evolving over time (as has occurred for instance in Kivu Swahili and Katanga Swahili, based on specific contact settings and also social factors, cf. Labov 2001), others reflect speakers’ free variations that are idiolectal and dependent upon the social and pragmatic context of a specific utterance or communicative action. In Kisangani, for instance, speakers can employ as much of a broad linguistic repertoire with divergent realizations of Swahili (Nassenstein 2015) as they can in Bujumbura, where both Congolese and Tanzanian dialects are widespread (Nassenstein, this volume). In Bunia Swahili/Ituri Kingwana, speakers can choose out of three lects, whereby an acrolectal, mesolectal, or basilectal realization represents a single speaker’s choice and potentially marks his/her identity. Thomason (1999) and Lüpke & Storch (2013) address speakers’ choices in processes of language change.

tourism (Mietzner 2019); in this context simplified Swahili at the beach is also analyzed (Nassenstein 2019), sometimes with specific reference to strategies of concealment, taboos and sex tourism (Nassenstein 2016b). Young beach vendors often use a contact language labeled as “Coasti Slang”, which combines lexical items from tourist languages such as German, French and Italian with a Swahili matrix and certain morphosyntactic features from local Mijikenda languages. This and other emerging practices deserve a more thorough and in-depth analysis as well, as they yield insights into processes of rapid socioeconomically triggered change that also affects language.

There is a growing body of literature, mostly compiled by anthropologists and/or social geographers, on the dynamicity and translocality of cultural concepts, mobile economies and sociocultural transfer from the East African coast across the Indian Ocean to places such as , Dubai, Mauritius, the Comoros etc. (see, among others, Declich 2018, Verne 2012). These studies, which usually focus on migrant and diasporic communities, also include linguistic aspects, of course. However, specific linguistic studies on translocal Swahili and linguistic transfer are not yet available. However, in linguistic analyses of the mobility and sociolinguistic dynamicity of Swahili speakers, varieties and contact phenomena, they have to be taken into consideration – and can serve as inspiring ethnographic studies that may also have an impact on newly emerging linguistic ethnographies of Swahili-speaking communities. The increasing importance of virtual or mobile communication in social media is also reflected by scholars’ recent studies (Shen 2017), and can be expected to yield still more results in the future. The use of Swahili in media such as movies or computer games is also a rather new and aspiring field of research (Thomas 2017, among others).

Exciting new strands of research will hopefully also allow a closer look at variation in Swahili in remote and unusual settings, where few and often marginalized speakers make use of the language, such as for instance among heritage speakers on the island of Nosse Be (Madagascar), the use of Swahili by South Sudanese hip hop musicians and cross-border traders between Kampala and Juba, among Congolese soldiers in the capital Kinshasa (at its westernmost point of diffusion), or in its divergent realizations among groups of Rwandan, Burundian and Congolese immigrants in Brussels 27 , or among Kenyans, Ugandans and Tanzanians in London-based diasporic communities (Hadjivayanis 2015).

27 In analogy with Meeuwis (1997), who has conducted a study on Lingala among Congolese and Belgo- Congolese speakers in Brussels.
