This research paper explores much of the basic and background knowledge of English and Bangla sentence patterns or structures as well as tries to compare and contrast between these two very languages, English and Bangla at the sentential levels. As it is known the concept of basic sentence structures is necessary for classroom teaching and learning to perceive the subtleties of language at the highest unit of grammar, this study is expected to facilitate the understanding of bilingual relationships between them (may be as a native or a foreign language) for researchers, teachers, learners and/or speakers of both the languages. The ideas drawn from the findings in this paper will also help one in the field of translating amid these two languages which is pedagogically very significant as well. For a few dissimilarities, we often notice greatly faulty grammatical constructions both in English and Bangla, when learners or users shift from one to another. So, this study of the two types of sentence patterns along with their components will be of considerable use to many, specially to those who teach, learn or use these languages.
