The Persistence of Fossilization in English Language Learning and Acquisition

Abstract

Fossilization is widely recognized as one of the most persistent and complex difficulties in learning and acquiring the English language, especially within the domain of second language acquisition (SLA). This study explores the characteristics and durability of fossilization in learners’ interlanguage through three key research questions: (1) Which cognitive, linguistic, and affective variables lead to the development of fossilization in English language learning? (2) Is fossilization a permanent condition, or can it be reversed during second language development? (3) What types of pedagogical interventions can reduce or overcome fossilization in formal educational settings? The study is theoretically grounded in Interlanguage Theory, the Critical Period Hypothesis, and cognitive-interactionist approaches. It employs a qualitative descriptive method based on a critical examination and synthesis of both foundational and recent literature in SLA. The analysis demonstrates that fossilization emerges from a multifaceted interaction between internal elements—such as first language interference, restricted attentional capacity, and the automatization of incorrect linguistic forms—and external influences, including teaching methods, the nature of feedback, and sociocultural exposure. The results also suggest that although certain fossilized forms are highly resistant to modification, carefully designed instructional techniques and continuous learner awareness may support partial defossilization. The study concludes that fossilization should not be interpreted as a deficiency on the part of learners, but rather as a natural outcome of language development influenced by cognitive limitations and learning conditions. A thorough understanding of its persistent nature is therefore crucial for developing effective pedagogical strategies that promote linguistic accuracy and sustained language growth among English learners.
