Abstract

This study sought to investigate: a) To what extent, the teaching of affixes affect in developing the students' vocabulary b) Does the process of teaching the affixes in English enhances vocabulary knowledge among Yemeni EFL learners? The participants of this study were forty-two students. They were second-year students enrolled at the Bachelor program in the Arts college at the University of Dhamar in Yemen in the academic year 2022 /2023. To answer the questions of this study, it was necessary to collect data which are related to the participants’ vocabulary and its influences by teaching affixes'. Data were collected by a test. The results of the study indicate that there are statistically significant differences at the level of significance (≤ 0.05) between the mean scores of the students of the two groups (experimental and control) in the post application of the vocabulary test in favor of the students of the experimental group, and this difference can be attributed to the teaching treatment which was used (the proposed program) which led to the development of  the participants' vocabulary, through the program of teaching the morphological affixes. It was observed also that the program was very interesting and useful. It has increased learners' awareness of morphological rules and has added to the students' vocabulary as well.
