The current study looks into the reasons and perspectives students have about the use of their first language in English classrooms. It analyzes their opinions on different issues connected to first language use. The analysis for this paper was conducted on data from an online survey and follow-up interviews based on 51 total participants. The results showed that students used their first language for a variety of reasons. The amount of first language used also differed. The results also showed that patterns emerged when considering the participants' language backgrounds, age, and the English language proficiency level. The results of this study will help teachers and students understand the reasons students have for using their first language in English classrooms. By knowing these reasons, students may be able to eliminate them and eventually improve the English language learning process. Teachers can also use the results to modify their classroom management to reduce the amount and frequency for first language use. To sum up, the research showed that students have a variety of reasons for and opinions about why they use their first language in their English classrooms, and that usage may be affected by a number of variables that need further research and study.
