How to say "respond" in Japanese

Choosing the right word
  • 応ずるおうずるJLPT N2approx.Common
    ichidan verb (-zuru), intransitive verbCovers answering, responding, and meeting demands; it is the する-verb counterpart of 応じる, used in the same kinds of situations, such as responding to a call or request.
  • 応じるおうじるJLPT N3approx.Common
    ichidan verb, intransitive verbUse it for responding to a request, demand, or invitation; it often implies accepting or complying with what is asked rather than simply giving an answer.
    我々われわれは彼かれらの要求ようきゅうに応おうじなければならなかった。↗
    We had to yield to their request.
  • 応えるこたえるCommon
    ichidan verb, intransitive verbCovers answering and responding, but its characteristic use is meeting demands or expectations — living up to what is hoped or asked of you.
    あなたは御ご両親りょうしんの期待きたいに応こたえるべきだ。↗
    You ought to live up to your parents' hopes.
  • 言い返すいいかえすCommon
    godan verb, transitive verbFor replying in words — answering back or retorting to what someone has said; the response is speech, often with a hint of talking back.
    ベスは言い返いいかえしましたが、お母かあさんは彼女かのじょにものすごく太ふとりすぎていると注意ちゅういしました。↗
    Beth protested, but her mother reminded her that she was incredibly fat.
  • 感ずるかんずるJLPT N2approx.Common
    ichidan verb (-zuru), transitive verb, intransitive verbSeldom the word you want for 'respond': it really means to feel — to be moved, touched, or impressed by something — and its 'respond (to)' sense is marginal.

Use 「応じる」 (or its する-verb counterpart 「応ずる」) for responding to requests or demands, 「応える」 for meeting expectations, 「言い返す」 for replying or talking back, and leave 「感ずる」 aside, since it is about being moved rather than responding.
