A set of Context Sensitive Grammar (CSG) rules to translate Bangla imperative, optative and exclamatory sentences into English are introduced in this paper. In this paper, sentences are considered according to the function and purpose of the user rather than structure of the sentence. Three algorithms are implemented to complete major three steps of machine translation system (i.e., parsing, transfer and generation). The experimental results shows that the performance of the proposed machine translation framework is quite appeasement and efficiency is compared with Google Translator for some selected sentences which are quite satisfactory.
