This thesis examines the nuances of honorification in Bangla and its connection with two other related phenomena, i.e. copula constructions and definiteness marking. Bangla has three levels of honorification in the 2nd and 3rd person - the high, mid and non-honorific (Dasgupta 2003). However, a micro level investigation of this phenomenon reveals that honorification is manifested differently in the varieties studied here. While the Kolkata Bangla variety has three levels of honorification, Purba Medinipur has only two, and the Purulia variety does not show any trace of it at all, though the current generation of Bangla speakers in Purulia have been taught to use it sparingly in their regular conversation. Upon linking honorification with copula constructions, we observe that there is a unique presence of the baT copula in the Purulia variety, which has featural similarities with the Odia aTe. However, unlike the Odia aTe, this copula cannot be inflected to mark honorification. The present study claims that such an occurrence is linked with the TAM carrying feature of copulas. Finally, the thesis investigates the lack of honorification and links it with the definiteness marker -Taa in this language. This marker acts as a valve that restricts honorification agreement in Bangla. To explain this phenomenon, we follow the Extended Poser Principle, proposed by Embick and Marantz (2008), and contend that in Bangla, the ‘strong’ dis-honorific features of the definiteness marker -Taa blocks the mandatory manifestation of honorificity on the predicates which are associated with lexically and inherently honorific subjects.
