This study focuses on the word order between ”Japanese and Korean” and considers how to make Korean sentences. The results are as follows: “MASU” in Japanese makes a special word order which there is not in Korean. : The Negation and The Preterit Tense are located in the next of “MASU”. But also Korean doesn’t have these arrangements. : Two Postpositions can be compounded also in Korean. But there is the special case when it could be expected which of two postpositions can be located in front of Verb. In this case, Koreans can leave out the expected one and must write just another one. : “SEYO” in Korean makes the word arrangement which Japanese doesn’t have.
