AN ANALYSIS OF STUDENTS’ PERSPECTIVES ON THE ROLE OF AFFIX MASTERY ON VOCABULARY DEVELOPMENT

Abstract

Affix mastery is a key component of vocabulary knowledge that enables learners to interpret unfamiliar words and enhance their overall language proficiency. In the context of EFL undergraduate students, affix mastery plays a vital role in supporting vocabulary development by fostering morphological awareness. This study investigates EFL students’ perspectives on the role of affix mastery in vocabulary learning, focusing on eighth-semester students of the English Education Department at Universitas Pancasakti Tegal. Employing a case study design with a descriptive qualitative approach, data were collected through semi-structured interviews with selected participants via criterion-based purposive sampling. Thematic analysis revealed three major findings: (1) students recognized affix mastery as an effective strategy for understanding and expanding vocabulary; (2) unfamiliar affixes, particularly those of Latin and Greek origin, posed challenges in recognition and interpretation; and (3) some students preferred decoding word formation over memorization, while others relied on rote learning. Overall, students perceived affix mastery as a valuable skill for improving vocabulary comprehension, promoting independent learning, and increasing confidence in language use.
