This study investigated the language styles used by teachers in English classrooms at SMPN 1 Banda Aceh, employing a qualitative descriptive approach. Conducted at a highly regarded educational institution with five English teachers, the research focused on three teachers instructing eighth-grade classes. Data collection involved audio recordings and structured interviews to capture and analyze teachers' language during classroom interactions. The findings identified three primary language styles: formal, consultative, and casual. This study also explored the reasons behind these language style choices. Formal language established a respectful learning environment, consultative language encouraged critical thinking and participation, and casual language built rapport and open communication. The research contributed valuable understanding for educators to tailor their communication strategies, enhancing the overall learning experience in English language classrooms.
