Phrase-Level ATR Vowel Harmony in Anum—A Case of Recursive Prosodic Phrasing

(1) Like many other Kwa languages, Anum employs a pattern of [ATR] vowel harmony that is regressive and [+ATR] dominant (RVH). This paper analyses RVH as a phrasal process which takes into account recursive phonological phrases. The proposal argues for an application of the process within and across non-maximal phonological phrases (φ) and a blocking of application across maximal phonological phrases (φmax). (2) Investigating RVH in Anum in more detail, the size of constituents and the complexity of sentence structures are varied. Target sentences were recorded and transcribed for [ATR] vowel harmony. (3) The empirical data show that RVH applies frequently between words that belong to either the same or to different syntactic constituents, but is blocked between two verb phrases of a serial verb construction and between any word and a following sentence-final time adverbial. Interestingly, RVH occurs between a sentence-initial subject constituent and a following verb or verb phrase, independent of the size of the subject constituent and the remaining number of words in the sentence. (4) The proposed OT analysis accounts for RVH within syntax-phonology Match Theory and addresses both word-level and phrase-level harmony. The special behaviour of subject constituents that prosodically phrase together with verbs and with constituents of the verb phrase (VP) is discussed. Either a phonological well-formedness constraint or a syntactically distinct input may account for phrasing effects with subject constituents in Anum
