TRANSITIVITY:

  • Type: 自動詞(じどうし) (intransitive)
  • No standard transitive pair
  • Pattern: (ちが)

SENSE 1 - DIFFERENT:

  • XとYが(ちが)う: X and Y are different
  • Xと(ちが)って: unlike X
  • 全然(ぜんぜん)(ちが)う: completely different

SENSE 2 - WRONG/INCORRECT:

  • (こた)えが(ちが)う: the answer is wrong
  • (ちが)います: No, that's not right (polite denial)
  • ちょっと(ちが)う: a bit wrong/off

RELATED WORDS:

  • (ちが)い: difference (noun)
  • 間違(まちが)い: mistake
  • 間違(まちが)える: to make a mistake
  • (こと)なる: to differ (formal)

ASPECT (ている):

  • (ちが)っている: is different, is wrong (stative — describes a current state, not an ongoing action)
  • Note: (ちが)う is one of a small group of stative verbs (along with (すぐ)れる, ()る, そびえる) that describe inherent states. Both plain (ちが)う and (ちが)っている are used to express the stative meaning; (ちが)っている often highlights that a specific item deviates from a norm or expectation. 電話番号(でんわばんごう)(ちが)っています = 'the phone number is wrong (compared to what it should be).' The plain (ちが)います is the standard polite denial 'no, that's not right.'
