How to say "helpless" in Japanese

Choosing the right word
  • 心細いこころぼそいJLPT N1approx.Common
    i-adjectiveThe emotional sense of helpless: feeling anxious and forlorn when you face something alone, with little confidence or support, as on a first day in a strange place.
    彼かれが帰かえってきたのは、ホームシックにかかったからではなく、ふところが心細こころぼそくなったからである。↗
    He came back not because he was homesick, but because he was running short of money.
  • 無援むえんCommon
    nounNames the objective condition of having no one's aid or backing, not the feeling of helplessness; for the ordinary sense of helpless this is seldom the word you want.
  • か弱いかよわいCommon
    i-adjectiveReally means physically weak, feeble or frail; it maps to helpless only for someone so delicate or frail that they seem unable to cope alone, not for helplessness in general.
    彼女かのじょの子こどもはか弱よわかった。↗
    Her child was in delicate health.
  • 頼りないたよりないCommon
    i-adjectiveCovers helpless as the forlorn sense of having nothing or no one to depend on; it can also describe the person or thing that is no help to rely on.

Use 「心細い」 for the anxious, forlorn feeling of facing something alone, 「頼りない」 for lacking anyone or anything to depend on, 「か弱い」 for physical frailty, and 無援 for the bare state of being without aid.
