Stroke Order

Meanings

  • silence in group or public settings, sometimes read as politeness or self-restraint
  • not necessarily shy; can reflect preference for listening
  • may apply to moments of quiet in discussions, not just overall personality

Etymology

無 (mu) + 口 (kuchi) combine to express the sense of ‘without mouth’; the compound historically came to denote someone who speaks little, yielding the modern sense of taciturnity.

Composition

  • 無: ‘without, none’
  • 口: ‘mouth’
  • the combination yields a sense of ‘without mouth’, i.e., not speaking

Usage

Used as a na-adjective to describe a person by a trait; appropriate in neutral descriptions and in both spoken and written Japanese; in formal writing it often conveys a reserved or low-verbosity persona rather than a defect, and it can describe habitual behavior or a temporary state in a discussion.
💡 Tips
Mnemonic: think of 無 as no and 口 as mouth; together they form no mouth, which helps recall the meaning of a person who speaks little.
