This generative-transformational model of Capanahua phonology aims (1) to make available to linguistic science data analyzed from the point of view of an explanatory, unified theory of language; and (2) to test some conclusions suggested by those data, with respect to language universals. Chapters treat phrase structure rules, transformational rules, the phonological features, morpheme structure rules, morphophonemic rules, and stress and pitch rules. A summary, sample lexicon, and bibliography conclude this work. (AMM)
