In contemporary Japanese, some Chinese (or Kango) includes both adjectival verbs and nouns. There are two forms that can be used to modify the predicative verb clauses, “adjectival verb ni (adverbial form) + predicative verb clause” and “noun de(case marker) + predicative verb clause.” The study aims to discuss this area with an intriguing question: Based on different situations, which form should we use to modify the predicative verb clauses? With the analysis of the Balanced Corpus of Contemporary Written Japanese (BCCWJ-Chunagon) and the examples shown in this study, differences between the two forms can be fully investigated and explained.
