This article delves into the debate surrounding the optimal age for attaining native-like proficiency in Second Language Acquisition (SLA). Focusing on the Critical Period Hypothesis (CPH), it weighs arguments favouring early childhood learning against empirical evidence challenging this notion. These studies show that successful adult language learners can achieve near-native proficiency despite linguistic problems, while emphasizing their capacity to overcome these obstacles with dedication and strategic approaches. The article, furthermore, explores additional factors influencing SLA, including motivation, learning environment, and language exposure, which highlights the significance of intrinsic motivation and diverse learning strategies in facilitating language learning process. By considering these factors, a nuanced understanding of SLA emerges, suggesting that adult learners possess the potential to reach significant levels of language proficiency, thereby enriching scholarly discourse and informing pedagogical practices.
