How to say "capability" in Japanese

• 力量りきりょうCommon
  nounCovers a person's overall ability or capacity to accomplish something, often with a nuance of demonstrated talent. Typical when evaluating whether someone has the capability for a demanding role or task.

• 手腕しゅわんCommon
  nounRefers to capability as practical, hands-on skill in executing work — the knack of getting things done. Natural for managers, negotiators, or professionals whose competence is shown in results.
  製品せいひん販売はんばいには天才的てんさいてき手腕しゅわんが必要ひつようなときもある。↗

  Selling products sometimes requires having a stroke of genius.
• 敏腕びんわんCommon
  na-adjective, no-adjectiveEmphasizes capable, adroit competence — being quick and skillful in action. Often describes a shrewd, capable person; it highlights deftness more than raw ability, so it fits contexts of adept handling rather than potential.
  彼かれは若わかかったが、敏腕びんわんだった。↗

  Young as he was, he was a man of ability.
• 力ちからJLPT N4approx.Common
  nounThe everyday word for power or strength; as 'capability' it is the broad, plain choice for someone's ability or capacity to do something. Suits general statements of ability but lacks the evaluative nuance of the other options.
  あなたは集中しゅうちゅうする力ちからを失うしなってしまった。↗

  You've lost the ability to concentrate.
• 器量きりょうCommon
  nounMeans a person's calibre or capacity — the measure of what they are equal to handling. It can also refer to looks in other uses, so for 'capability' it is best when assessing someone's overall stature or suitability.

Choose 力量 for overall ability and talent, 手腕 for practical executive skill, 敏腕 for deft competent handling, 力 for basic capability or strength, and 器量 for personal calibre or capacity.
