Comparative study on polysynthesis of the languages in North eastern Asia from typological and historical point of view

本研究以实地考察的资料为基础，考察了东北亚各语言在遗传上互不相关的形态和句法特征，并特别关注了不同程度的多合成。特别是在及物性、价态变化、性质预测、词缀与词缀的区分、词缀与连词的关系等方面积累了更多的研究成果，在这四年的会议和学术期刊上都有发表。通过这些研究，我们可以为北方语言的研究做出贡献。

In this research we examined morphological and syntactic characteristics of the languages of north eastern Asia, which are genetically unrelated with each other, with special focus on different degrees of polysynthesis, based on the data collected during filed work of each language. Especially we could accumulate more study results on transitivity, valency change, property predication, differentiation between affixes and clitics, and relation between lexical affixes and copula, which we have presented at conferences and in scholarly journals for these four years. Through these studies we could contribute to the study on the languages of the north.
