Abstract:
In the first part of this thesis, an extensive corpus study is used in order to determine the frequency of occurrences of different consonant clusters. It turns out that the clusters are best described with the help of a division of the Bangla lexicon into three strata: Sanskrit borrowings (SB), Native Bangla words (NB), and the other borrowings (OB). The NB stratum does not allow complex onsets while SB and OB allows complex onsets. Further, SB and NB do not allow complex codas, while these are found in OB. A range of other restrictions are discussed. Special attention is paid to voicing and to aspiration. An agreement analysis of voicing at the word medial position is argued for. A positional faithfulness analysis is presented for syllable final deaspiration. The analysis is presented in Optimality Theory (OT), following the stratification of the lexicon by Ito and Mester (in Japanese).
In the second part of the thesis, a morphological analysis in the Distributed Morphology framework (Halle and Marantz) is provided for standard verbal inflectional paradigms of Bangla. The inflectional categories that are covered by the analysis are ten categories of tense/mood (perfect, conditional etc), three levels of politeness (Formal, Polite and Intimate) in three persons. The Bangla analysis is compared with a similar analysis of the much simpler case of English verbal inflectional morphology. The analysis of Bangla in this second part compares a consonant-final stem with a vowel-final stem for all forms. Differences between the two Bangla cases show the existence of a number of phonologically motivated changes, some of which also relate to syllable structure (diphthongization, gemination). These are analyzed in Optimality Theory in the third part of the thesis, extending the analysis of the first part. The forms are thus accounted for by the morphological analysis in DM and following phonological changes on them, analyzed in OT.
