This mixed-method study assesses and evaluates the effect of etymological and
morphological vocabulary instruction on the adult EFL learners' receptive/
productive vocabulary knowledge. Indeed, the primary purpose of this study is to
observe the impact of etymological and morphological instruction on adult B1 level
(CEFR) EFL learners in Turkey. Forty-eight adult EFL learners were selected and
randomly assigned to two groups (24 participants in each), one as the experimental
and the other as the control group. Two tests were prepared by using Wesche and
Paribakht‟s (1996) Vocabulary Knowledge Scale (VKS) to test receptive and
productive vocabulary knowledge. The tests were administered to both groups
before and after the study. While the experimental group‟s participants received
etymological and morphological instruction for two months, the participants in the
control group were taught through conventional school instruction. Statistical
results and the interviews revealed a significant and positive effect of etymological
and morphological instruction on the experimental group members‟ receptive and
productive vocabulary learning.1
