A case study in Code-Mixing among Jahangirnagar University Students

English is, no doubt, a widely spoken language all over the world, which substantially influences its development. Bangladesh is no exception, and here English is taught at all levels of education and recently, it has been seen that in most of the universities of Bangladesh, students most of the time, when they speak with other students, use English in their speaking extensively, and many times, they mix English with Bangla. This tendency of code-mixing has brought some changes in Bangladeshi people and their culture because a language normally carries the culture of that language. So, this paper was meant to present how the mixture of English language with Bangla language is having an impact on both English and Bangladeshi cultures. To do so, it empirically through qualitative and quantitative methods found out the areas (the causes and patterns) in which English is mixed with Bangla by the students of Jahangirnagar University. The study also found out that excessive and sometimes unnecessary use of English detered communication. It gave a suggestion that speakers should learn or be taught to use both languages correctly. Finally, it provided some recommendations for the students to facilitate the learning of these two languages for the betterment of both English and Bangladeshi cultures. Key words: Code-mixing, mixture, language, code-switching.
