A Phonological Analysis of Labialization in Anaañ: Distribution, Conditioning and Functions

This study examines labialization in Anaañ from a phonological perspective, focusing on its distribution, conditioning, and function in the word structure of the language. It investigates the occurrence of labialization in relation to the rounded vowels /o/, /u/, and /ʉ/ the approximant /w/, while also examining the phonological status and distribution of the independent consonantal phonemes /n/, /ŋ/, and /ŋw/, /k/ and /kw/, including /g/ and /gw/. The analysis is grounded in autosegmental phonology and distinctive feature theory, which provide complementary perspectives for accounting for the representation, association, and contrastive behaviour of labial features. Data are drawn from 30 native speakers of Anaañ through word-list elicitation, recorded speech, and interviews. The study argues that labialization in Anaañ is a systematic phonological process conditioned by specific segmental and prosodic environments rather than a purely phonetic phenomenon. The findings reveal that labialization involves the association of the [labial] feature with consonantal segments and is conditioned by the phonological properties of neighbouring segments. It concludes that labialization is a systematic component of Anaañ phonological structure, with identifiable segmental conditioning and contrastive functions.
