This study is about how people give negative responses to yes-no questions. From the corpus "Female Speech(workplace version)", 21 examples using words like "いいえ(No)" and 20 examples not using words like "いいえ(No)" were extracted. Negative responses are divided into two groups. One is the group of negative responses that do not add new information to the foregoing speech, and the other is the group of those that do add new information. This result suggests that teachers should not persist in teaching sentence patterns in textbooks, but pay attention to daily conversation, and teach Japanese beyond textbooks.
