Two Patterns of /a/ and /o/ Alternation in Subanon Sharon Bulalang UNIVERSITY OF HAWAI‘I AT MĀNOA Two patterns of alternation affect the phonemes /a/ and /o/ in Subanon, an underdocumented Austronesian language spoken in the southern Philippines. Under suffixation, /a/ becomes /o/ in the antepenult (Pattern 1), and /o/ becomes /a/ in the penult preceding a palatal glide (Pattern 2). Pattern 1 has no apparent synchronic motivation, but comparative evidence shows that Proto-Subanen *a weakened to schwa when placed in pretonic position through suffixation, and that schwa from any source then became Subanon /o/. Pattern 2 is similar to a Subanon process called “partial vowel harmony assimilation,” as well as to the alternation of final -əy/-əw with penultimate -ay/-aw in Western Bukidnon Manobo. However, in both cases, these processes turn out to be unrelated. In conclusion, Pattern 2 shows no clear synchronic and diachronic motivation, and we are left with a descriptive statement without an explanation. 1. INTRODUCTION.1 Western Subanon [ISO 639-3 suc] (henceforth, Subanon) is an indigenous minority language in the Philippines spoken by about 300,000 people in the southwestern part of the Zamboanga Peninsula of Mindanao. Subanon is one of a small subgroup of languages called Subanen, that belongs to the Greater Central Philip- pines (GCPH) branch of the Austronesian language family (Blust 1991, 2005; Lobel 2013; Simons and Fennig 2018). Figure 1 shows the position of Subanon in relation to the other Subanen languages. Figure 1 reflects the fact that the Western subgroup of Proto-Subanen (PSUB) diverged prior to the breakup of the other Subanen languages. Additionally, it identifies the eight members of the Subanen subgroup divided into Western and Nuclear Subanen. The Western subgroup includes only Subanon and Western Kolibugan, while the Nuclear subgroup encompasses Tawlet-Kalibugan, Salug-Godod Subanen, Southern 1.

Special thanks to Laling Alas’as, Annaliza Bulalang, and Gloria Lumapang, as well as a number of other Subanon speakers who speak the Malayal dia- lect, from whom the data were elicited. I am also grateful to William Hall and Shaira Estioca for assisting me in data collection, to Thomas Dougherty and Bryn Hauk for sharing insights valuable to this study, and to two anonymous reviewers and my committee members, Robert Blust (chair), Gary Holton, and Victoria Anderson, for reading several drafts of the paper and providing helpful suggestions for improvement.

MAP 1. LOCATION OF SUBANON AND THE NEIGHBORING SUBANEN LANGUAGES (LOBEL 2013:321) 3. PREVIOUS STUDIES ON THE PHONOLOGY OF SUBANON. Being an underdocumented language, there has been very little work done on the phonol- ogy of Subanon. Synchronic studies include phonemic analysis (Hall 1967, 1997), a description of the orthography (Hall 1972), and a description of the standardization of the orthography (Hall 2014). Only a few diachronic analyses of this language have been pub- lished. Banker (1958) is an investigation of the origin of the /gl/ cluster where the g- in the cluster is analyzed as deriving from the final -g of the case markers og, nog, and sog; Reid (1973) is an exploration of the evolution of the Philippine languages from the four-vowel system of Proto-Philippines; Lobel’s (2013:318–59) historical-comparative work on Subanen languages producing “618 lexical reconstructions of Proto-Subanen” provides the major resource for analyzing the /a/ to /o/ alternation diachronically; and Blust and Nielsen (2016) shows that Proto-Austronesian *ma- ‘stative’ metathesized in Subanon only before base-initial b- and p- to avoid widespread dispreference for dissimilar labials as the onsets of successive syllables.
