How to say "insist" in Japanese

• 言い張るいいはるCommon
  godan verb, transitive verbCovers the core sense of 'insist': stubbornly maintaining a claim in the face of doubt or opposition. Use it when someone will not back down, as when insisting on one's innocence.
  彼かれらはそれが本当ほんとうだと言い張いいはった。↗

  They asserted that it was true.
• 叫ぶさけぶJLPT N3approx.Common
  godan verb, intransitive verbIts basic meaning is to shout or cry out; the 'insist' sense is clamoring — insisting loudly and publicly for or against something. It suits protest or advocacy, not calm private insistence.
• こだわるJLPT N1approx.Common
  godan verb, intransitive verbCovers 'insist on' in the sense of being particular or fastidious: caring intensely about a detail, method, or quality and holding to it. Often carries a nuance of fixation, sometimes excessive.
  その男の子おとこのこはあくまでも髪の毛かみのけを伸のばすことにこだわった。↗

  The boy persisted in wearing his hair long.
• うたうCommon
  godan verb, transitive verbReally means to declare, state, or stipulate — formally setting out a position or term — so it matches 'insist' only loosely; for everyday insisting it is seldom the word you want.

Use 「言い張る」 for stubbornly asserting a claim against resistance, 「叫ぶ」 for insisting loudly as protest or clamor, 「こだわる」 for insisting on details out of particularity, and 「うたう」 only for formal declaration or stipulation.
