Aspectos da fonologia Marubo (Pano): uma visão não-linear

Abstract

This work deals with aspects of Marubo (Pano) phonology under the perspective of Non-Linear Phonology. Following the assumptions of Syllable Theory, we search for underlying syllable pattems and their possible surface manifestations. The intemal organization of speech sounds, as well as the types of rules involved in phonological processes, such as vowel and nasal harmony, are accounted for on the basis of the model of Feature Geometry. Under the view of Metrical theory, we search for an account of stress assignment at the word level and above it. We also look for an explanation for the trochaic-iambic altemations resulting from case marking, as well as for the interaction between those altemations and some segmental and nonsegmental processes, such as vowel deletion, ressyllabification, and vocalic feature spreading to underlying unspecified vowels. The stress-syllabification interaction is also approached under the famework of Optimality Theory.
