Choi Soyoung This paper elucidated the ongoing changes observed as variations in the learner’s actual language for Korean language history education. Specifically, syntactic pattern variations in usage of conjugation were discussed. Ongoing changes have not yet been completed, so it is easy to take an interpretative view of the language education content. Learners can examine the variation that appears to be an ongoing change in their intuitive and actual language lives, identify the sociality of this change. It may also be possible to trace the history of this change and discover a basis for interpreting the change in terms of its persistence. Furthermore this investigation may be conducted in conjugation with already completed changes that exhibit similar aspects. k e y w o r d s Grammar Education, Korean Language History Education, Ongoing Change, Variation, Conjugation, Imperative Constructions with Adjectives, Interpretation, Inquiry
