How to say "boldly" in Japanese

• ズバリJLPT N1approx.Common
  adverb (with と)Boldly in the sense of saying or settling something bluntly and decisively, without hedging — hitting the point squarely. Typical of delivering a frank answer, verdict, or demand straight to the point.
• 敢然かんぜんCommon
  adverb (with と), taru-adjectiveBoldly as in bravely and resolutely facing a challenge — courage and firm resolve in bearing, not bluntness of speech. Suited to confronting danger, opposition, or a difficult task with determined composure.
  神かみを信しんじ、敢然かんぜんと敵てきに向むかった、そのクリスチャンの剣闘士けんとうしは、たくさんの敵てきを倒たおした。↗

  Putting his trust in God and taking the bull by the horns, the Christian gladiator defeated many adversaries.
• 思い切っておもいきってCommon
  adverbBoldly as in daring to act, taking the plunge after hesitation — decisiveness in making a move. Natural when you finally quit a job, make a big purchase, or speak up despite reservations.
  彼かれは思おもいきって意見いけんを発表はっぴょうしない。↗

  He dare not express his opinion.
• くっきりJLPT N1approx.Common
  adverb (with と), suru verbNot the manner-of-acting sense; here 'boldly' means clearly standing out — a sharply defined outline, print, or image. For bold action this is seldom the word you want; it really describes visual distinctness.
  その木きは空そらにくっきりと浮かび上うかびあがっていた。↗

  The tree was clearly defined against the sky.

For boldness in manner choose 「ズバリ」 (bluntly, decisively), 敢然 (brave resolve), or 「思い切って」 (daring to act); 「くっきり」 is only for visual distinctness.
