The purpose of this study is rousing a recent attention to the changes of languages of Korea and near Korean peninsula, as well as reviewing the historical or traditional flow of Korean language teaching. Additionally, this study also discussed about the alternative methodological possibilities of analysing the origin of languages based on gene-culture coevolution theory adapting language phylogeny, not by internal reconstruction of traditional language research. Looking backward over past times before modern era, teaching and learning Korean language as a ‘foreign’ language were slowly changed from ‘oral(spoken)-focused / borderland-based / hereditary succession / natural acquisition’ circumstances into ‘document(written)-focused / government-based / professional training / organized learning’ system.
