Contrastive Linguistic Studies on Factors for Grammaticalization in Japanese and Korean

对日语和韩语中复合格助词和复合动词的详细考察表明，日语中复合格助词和复合动词的语法化频率高于韩语。可以证明，两种语言在语法化方面的差异是由形态句法的差异造成的，其特点是朝鲜语区分了词和分句/句子的地位，而在日语中，词和分句/句子可能以融合的状态存在。

Detailed examination of compound case particles and compound verbs in Japanese and Korean shows that they are more frequently grammaticalized in Japanese than in Korean. It can be demonstrated that this difference in grammaticalization between the two languages is caused by differences in morphosyntax, characterized by the fact that Korean differentiates between the status of word and clause/sentence, whereas in Japanese it is possible for word and clause/sentence to exist in a fused state.
