The sentences with the compound function word "KIKKAKE" sometimes result in non-sentences when they are correct based on the grammar explanations in textbooks for Japanese language learning. In this paper, I focused on <X o KIKKAKE ni> and investigated grammar explanations and usage in Textbooks. In addition, I conducted an online survey to clarify the causes of non-sentences and their correction in the sentences using the compound function word "KIKKAKE." Furthermore, based on the verification of textbooks and the survey result, I discussed matters that should be added to Textbooks to use the compound function word "KIKKAKE" correctly.
