日本語話し言葉コーパスに見られる「させてもらう」と「させていただく」の使用について

Abstract

In this study, I analyzed and examined the use of ‘Sasetemorau’ and ‘Saseteitadaku’ using “Corpus of Spontaneous Japanese (CSJ)” as research materials, and found the following. ⅰ) ‘Sasetemorau’ and ‘Saseteitadaku’ have something in common; their use is more common among people in their 20s to 30s, who are relatively younger, and the factors such as their birth year and gender are not particularly pertinent. ⅱ) ‘Sasetemorau’ is an expression used primarily to show thankfulness or appreciation for the speaker’s act of “did something” or “will do something” in his or her personal conversation, rather than considering the relationship with the listener in front of him or her.　ⅲ) ‘Saseteitadaku’ tends to be used more often in situations where there is a large audience than in a one-to-one conversation style such as “dialogue,” and is often used mainly as a “preface expression” or a “close expression.” ⅳ) It is presumed that ‘Saseteitadaku’ which is not used as an original usage, will be used in accordance with the flow of honorifics that prioritize the listener and the scene spoken, and that only ‘morau’ of ‘Sasetemorau’ will be used instead of ‘itadaku’. ⅴ) When one uses a word related to the act of speaking to the listener, there is a tendency to use a new form of honorific, ‘O/Go~ saseteitadaku’.
