This paper presents a synthesis of theoretical and empirical literature to re-evaluate the pedagogical utility of the first language (L1) in second/foreign language (L2) acquisition. While maximizing L2 exposure remains a foundational principle in instruction, traditional views that treat any native language use as an impediment are increasingly challenged. Recent scholarly consensus indicates that strategic, judicious integration of the L1 yields significant cognitive and emotional advantages. Specifically, the L1 functions as a vital mediational resource, helping lower-proficiency learners connect new vocabulary in the target language (L2) to their pre-existing conceptual frameworks. Furthermore, by facilitating the execution of complex cognitive tasks, L1 scaffolding helps mitigate cognitive overload and acts as an affective strategy to lower learner anxiety. In conclusion, this paper highlights that a balanced and principled use of the L1 does not hinder L2 immersion; rather, it serves as an essential scaffolding mechanism that enhances the overall process of second language acquisition. However, both L2 teachers and students should be cautious about over-reliance on the L1 in the classroom.............. Keywords:................. Second/Foreign Language, Pedagogy, Implications.
