A compound verb formed from ()う (to say) + ()う (to do together/mutually). The ()う suffix adds reciprocity — both parties are speaking. In practice, sense 1 (arguing) is more common than sense 2 (exchanging words).

USAGE:

  • Sense 1 often appears as the noun form ()()い (an argument, a quarrel)
  • Sense 2 is typically used with a quoted phrase or specific content being exchanged
  • The subject is usually plural or implies two or more people

COMMON COLLOCATIONS:

  • ()()いになる: to get into an argument
  • ()()いをする: to have an argument
  • 冗談(じょうだん)()()う: to exchange jokes
  • 悪口(わるくち)()()う: to trade insults

SIMILAR WORDS:

  • 口論(こうろん)する: a more formal word for arguing verbally
  • 喧嘩(けんか)する: to fight or quarrel; broader than ()()う, which is limited to verbal exchange
  • (はな)()う: to discuss; implies a calmer, more productive exchange
