The role of proper language use in enhancing teaching and learning during English lessons

The effective use of proper language is the heartbeat of successful English pedagogy. Language is not merely a vehicle for instruction but a transformative instrument that shapes thought, engagement, and understanding. This article examines how the deliberate and consistent use of proper English by teachers enhances learner participation, comprehension, and cognitive growth during English lessons. Grounded in an interpretivist qualitative framework, the study synthesises recent empirical research conducted between 2022 and 2025 within multilingual South African classrooms. It reveals that linguistic precision and clarity in teacher discourse foster academic confidence, creativity, and equitable access to knowledge. The findings demonstrate that when teachers model grammatically accurate, contextually appropriate English, learners internalise both linguistic competence and critical thinking skills. Furthermore, the study highlights the pedagogical and ethical responsibility of educators to use language intentionally, as it has a direct impact on classroom culture and learner motivation. Proper language use, therefore, transcends correctness, it becomes a catalyst for intellectual empowerment and cultural inclusivity. The article concludes that teacher training programmes should integrate advanced linguistic proficiency to strengthen teaching quality and learner achievement. The argument resonates globally, positioning language mastery as a cornerstone for sustainable education systems striving toward excellence, diversity, and innovation in language teaching and learning.
