Recent studies in Korea have investigated various topics concerning Lexical Approach; however, little attention has been paid to teaching grammar though Lexical Approach. The present study adopted the principles of Lexical Approach to teaching grammar to Korean L2 learners. A total of 170 college students participated in the present study, and Lexical Approach was applied to the experimental group. The positive effect of Lexical Approach on Korean L2 learners` grammar learning was borne out by the results of the present study. It was evident in the tests where the particular pragmatic functions were used as the prime. The study suggests that since the subjects in the experimental group were taught various examples as a form of lexical chunks and practiced producing sentences for various situations that may require particular chunks, not only the grammar structures but also additional information such as pragmatic properties of the lexical chunks may be stored together in their lexicon.
