The Diachronic Coronal-Velar Nasal Relationship Jenny Simone Lederer† † University of California, Berkeley E-mail: [email protected] 2. DIACHRONIC EXAMPLES ABSTRACT (2.1) Cuban Spanish This paper investigates the phonetic factors of diachronic A prototypical case of the alveolar nasal sifting to the nasal place change from the alveolar to the velar place of velar nasal is that of Cuban Spanish (Hammond 1976, articulation. Evidence is given from Cuban Spanish, Lederer 2000). In Cuban Spanish, all word-final instances Hausa, Brazilian Portuguese, and Chinese. There appear of a nasal consonant appear as the velar nasal []. By to be two distinct pathways leading to change. The first is contrast, in Peninsular Spanish, word-final nasals appear a pathway in which the word-final alveolar nasal becomes as the alveolar [n] (with the exception of dialects such as velar with no independent stage of phonemic word-final Andalusian, which also exhibits the word-final velar nasalized vowels (Cuban Spanish, Hausa, and certain nasal). dialectal groups of Chinese). In the second pathway Spain Cuba (Brazilian Portuguese), there is a documented stage of pa[n] pa[] ‘bread’ phonemically nasalized vowels.

The first from any phonological explanation of markedness and point to be noticed is that the Cuban velar nasal is unmarkedness. The focus on nasal place shift and the pronounced in a word-final environment. In Cuban reasons for this shift will exemplify the complexity of Spanish pre-consonantal nasals assimilate to the place of these specific phonetic/phonemic changes. Nasals are articulation of the following consonant: [emfasi] susceptible to place change simply because of their ‘emphasis’, [entufar] ‘to plug in’, [mao] ‘mango’, but nasality. in the word-final environment, the velar nasal serves as the This paper is organized as follows. In Section 2, several ‘default’ nasal. In continental Spanish, the system of unrelated languages will be examined in detail as evidence phonemic nasals consists of [m], [n], [].

Because the velar-nasal is pronounced acoustic and articulatory studies, which will serve as more word-finally, and in the unconditioned coda position evidence toward the specific acoustic and articulatory sporadically (Hammond 1976), the [] has now taken over reasons that these changes occur diachronically. And, many of the positions of [n]. finally, Section 4 will be a list of necessary phonetic Another crucial difference between the two dialects, a factors that serve as a roadmap for this specific diachronic key factor to the alveolar-velar sound change, rests on the process. quality of the vowel which precedes the word-final nasal. The vowels preceding nasals in continental Spanish are not phonologically nasalized, but the vowels preceding Newman (2000). Newman explains that the nasal nasals in Cuban Spanish are (Lederer 2000). Maria-Josep phoneme /n/ commonly occurs in syllable final-position, Solé (1995) experimentally demonstrates the difference and that, when it does, it is always homorganic with the between a phonologized pattern of pre-nasal vowel following consonant. This nasal-coda situation in Hausa nasalization in American English and phonetic co- seems at first very similar to the Cuban homorganic nasal articulatory pattern of pre-nasal vowel nasalization in coda phenomenon. However, Newman (p. 405) goes so Continental Spanish: far as to say that the nasal in this position should not be In (Continental) Spanish, vowels are oral for most of linked to the coda, but is in fact part of a “nasal their duration; onset of VP (velopharyngeal port) diphthong”, which behaves comparably to an oral opening is timed relative to the following nasal diphthong. This type of description raises the possibility consonant and peak VP size occurs at nasal consonant that Hausa vowels in pre-nasal position are phonemically onset across (speech) rates, which suggests that the nasalized as is the case in Cuba. motor commands for opening the velar port are part of (2.3) Chinese the instructions for the nasal consonant.

Chen exemplifies this indicates that opening movements are part of the ‘unidirectional merging’ by observing that in dialects that programming instructions for the vowel. It is argued merged to only two-way contrasts, either /m/ merged with that, in (Continental) Spanish, vowels followed by a /n/ or /n/ merged with //. The merges never resulted in nasal consonant are targeted as oral and are nasalized just word-final [m] and never resulted in just word-final as a result of a co-articulatory effect, whereas in [n].
