How to say "feeble" in Japanese

Choosing the right word
  • か弱いかよわいCommon
    i-adjectiveCovers the physical sense of feeble and frail, typically describing people or creatures that are delicate and easily harmed, often with a suggestion of cuteness or pathos.

    Her child was in delicate health.
  • 微弱びじゃくCommon
    na-adjective, nounUsed for feeble in the sense of faint or lacking strength, such as weak signals, faint light, or minimal force; it is a more technical or measured word than the others here.
  • 弱々しいよわよわしいCommon
    i-adjectiveDescribes something that looks or seems feeble, such as a weak voice, frail movements, or a sickly appearance; it emphasizes how weakness presents itself to the eye or ear.

  • 病弱びょうじゃくCommon
    na-adjective, no-adjectiveRestricted to feeble health: it describes a person of weak constitution who is often sick. If your 'feeble' is about illness or constitution, this is the word; otherwise it will not fit.
    彼かれは病弱びょうじゃくというハンデを負おわされている。↗
    He is handicapped by poor health.
  • 貧弱ひんじゃくJLPT N1approx.Common
    na-adjective, nounMeans poor, meagre, or feeble in quality, content, or build, as in a skimpy meal, thin argument, or puny physique; for bodily or moral weakness it is only a marginal choice.

    My knowledge of German is poor.

Choose by what is feeble: 「か弱い」 for delicate people or things, 微弱 for faint signals or strength, 「弱々しい」 for weak-seeming appearance or manner, 病弱 for poor health, and 貧弱 for things that are meagre or poorly made.
