Did you know?

  • The verb for 'to buy' is used in the phrase 買い被る (kaikaburu), which literally means 'to buy and cover' but figuratively means to overestimate someone's value or abilities.
  • The spoken word 買った (katta) sounds identical to the word for 'won' (勝った). Without seeing the kanji or hearing the context, a listener cannot tell if the speaker made a purchase or won a game.
  • While 買いました (kaimashita) is a complete sentence, Japanese speakers almost always omit the pronoun for 'I'. Including 'I' (私は) can actually sound unnatural or overly emphatic to a native speaker.
