How to say "combine" in Japanese

Choosing the right word
  • 組み合わせるくみあわせるJLPT N1approx.Common
    ichidan verb, transitive verbCovers the transitive sense of combining separate things: putting items, ingredients, colors or people together into a combination or pairing. A natural choice when you deliberately combine A with B.

    Can you match this coat with something a little more colorful?
  • 交えるまじえるJLPT N1approx.Common
    ichidan verb, transitive verbCovers combining as mixing one thing in among others so the elements are interspersed, such as blending an ingredient into a mixture. It is 'mix in' rather than assembling separate parts into a whole.
    その詩しは韻文いんぶんに散文さんぶんをまじえている。↗
    That poem mixes prose with poetry.
  • 合わさるあわさるCommon
    godan verb, intransitive verbThe intransitive side of 'combine': things join, come together or unite — two parts merging into one. Use it when the subject is the things that combine, not someone doing the combining.
    しかもなお、石いしの大おおきいブロックが非常ひじょうにぴったりと合あわさっているので、ブロックの間あいだにナイフの先さきを差し込さしこむことができない。↗
    And yet the large blocks of stone are fitted together so closely that you cannot put in the point of a knife between them.
  • nounNot a way to say the verb 'combine': this noun, a shortened form of 'combine harvester', names the farm machine that harvests grain. For any other sense of 'combine' it is not the word you want.
  • 合わせるあわせるJLPT N3approx.Common
    ichidan verb, transitive verbTransitive: to join things together, unite them, or add numbers up. Choose it when you actively bring two or more things together into one, including the 'add up' sense for figures.
    3人にんは合あわせて50ポンド持もっていた。↗
    The three men had £50 between them.

Use 「組み合わせる」 or 「合わせる」 to combine things actively, 「交える」 to mix something in among others, 「合わさる」 when things join or unite on their own, and 「コンバイン」 only for the harvesting machine.
