Abstract
In this study, I use a corpus (I-JAS) to clarify the actual usage of "-te hoshii", "-te moraitai", and "-te itadakitai" by Japanese language learners and native Japanese speakers. The analysis revealed the following results: (1) In usage of requests, native Japanese speakers tend to use "-te itadakitai" rather than "-te hoshii" and "-te moraitai", (2) The use of the declarative form and "-ndesu" is seen only in Japanese learners, and (3) Regarding the "-to omou" form, Japanese learners tend to use "-to omoimasu" while native Japanese speakers tend to use "-to omotteimasu".
