ABSTRACT
This chapter presents a morpheme-plane analysis of four phonological processes from four languages. The first two examples are from Fula and Malayalam, where a morpheme at one end of a word triggers a phonological change in a segment at the opposite end. The third example comes from Dakota, where a phonological distinction between compound and reduplicative structures can be explained by differences in the planar representations of these morphological operations. The fourth example concerns an interesting tonal phenomenon in Hausa, where the tonal melody of certain suffixes is realized on the stem, causing an underlying tonal melody to be deleted. Lieber provides an analysis of consonant mutations in the noun-class paradigms using the formalism of autosegmental phonology. Mohanan claims that the facts of nominal derivation can best be accomodated within the theory of Lexical Phonology, where morphology and phonology are interwoven processes. Hausa presents a tonal phenomenon that is subject to a simple analysis under the Morpheme Plane Hypothesis.
