How to say "insistence" in Japanese

Choosing the right word
  • 主張しゅちょうJLPT N3approx.Common
    noun, suru verb, transitive verbThe word for insistence as the act of asserting a claim or position — maintaining that something is so, as when someone insists on their opinion in an argument.
    私わたしたちはその重要性じゅうようせいを主張しゅちょうした。↗
    We insisted on its importance.
  • 執着しゅうちゃくJLPT N1approx.Common
    noun, suru verb, intransitive verbSeldom the word you want for insistence: it really means attachment — an emotional fixation on something one cannot let go of — or adhesion; any insistence it conveys is tenacious clinging, not asserting a point.
    彼かれは弁護士べんごしになれるという希望きぼうに執着しゅうちゃくしていた。↗
    He clung to the hope that he could be a lawyer.
  • 力説りきせつCommon
    noun, suru verb, transitive verbInsistence as strongly stressing or arguing a point — pressing an argument emphatically for or against something. Fits when someone insists by emphasizing their case forcefully.
    火星かせいにはかつて原始的げんしてきな生物せいぶつが存在そんざいしていたと彼かれは力説りきせつしている。↗
    He contends that primitive life once existed on Mars.
  • 固執こしつCommon
    noun, suru verb, transitive verb, intransitive verbInsistence as stubbornly sticking to an opinion, theory, or belief and refusing to budge — persistence in holding a position rather than the act of asserting it.
    彼かれはまだ自分じぶんの意思いしに固執こしつしている。↗
    He still sticks to his opinion.

Choose 主張 for insisting as asserting a claim, 力説 for emphatically stressing a point in argument, and 固執 for stubbornly sticking to an opinion or belief; 執着 is really attachment or adhesion, seldom the word for insistence.
