Choosing the right word
  • 有力ゆうりょくJLPT N1approx.Common
    na-adjective, nounCovers 'convincing' in the sense of persuasive and likely to be true — a strong argument, hypothesis, explanation, or candidate. It describes the actual strength or plausibility of evidence, not mere appearance.
  • i-adjectiveCovers 'convincing' as in realistic or genuine-looking. It suggests something superficially resembles the real thing — a convincing excuse, story, or impersonation — without implying it is actually true or valid.

Use 有力 for an argument, theory, or candidate that is persuasive or most likely to be true; use 「それらしい」 for something that merely looks convincing or plausible on the surface without necessarily being so.
