In the Japanese writing system, kanji serve as the primary characters for representing the core meaning of nouns and verb roots (stems).12

  • Nouns: These are frequently written using one or more kanji. Often, nouns are formed as compounds, where two or more characters are combined to express a specific concept.1
  • Verb Roots: Kanji are used to represent the unchanging base or root of a verb. Because kanji cannot express the various inflected forms of the Japanese language on their own, they are paired with hiragana—a component of the kana syllabaries—to indicate grammatical markers, such as verb tenses, possession, and other inflections.12

By using kanji for the semantic "root" of a word and kana for the grammatical "glue," the Japanese writing system effectively balances the expression of complex ideas with the requirements of its inflected grammar.12
