How to say "ready" in Japanese

• 無造作むぞうさCommon
  na-adjective, nounCovers 'ready' in the sense of quick and effortless — a ready reply or ready wit — describing something done casually, without fuss or deliberation; it never means prepared.
• 気さくきさくCommon
  na-adjectiveReally means friendly and approachable — an easygoing, sociable person you can talk to freely. It matches 'ready' only marginally, and is seldom the word you want when translating 'ready'.
  ある意味いみでは、丁寧ていねい語ごは気きさくな雰囲気ふんいきを壊こわす。↗

  Polite language, in a sense, spoils a casual atmosphere.
• 良いよいJLPT N5approx.Common
  i-adjectiveCovers 'ready' as in prepared and all set, with everything sufficient or enough for the purpose; it fits questions and answers about whether preparations are complete.
• いいJLPT N5approx.Common
  i-adjective (よい/いい)Covers the same 'ready; prepared' sense as 良い — being all set, with enough done and nothing lacking. The two overlap heavily, and either works when asking whether preparations are complete.
  「今日きょうお父とうさんに会あいに行いく。進路しんろ相談そうだんだ」「いいですよ、そんなの」↗

  "I'm going to see your father today, about career counselling." "You don't need to bother with that."

For 'ready' meaning prepared or all set, use 「良い」 or 「いい」; 無造作 only fits the offhand, effortless sense of a ready answer, and 「気さく」, meaning friendly, is rarely the right choice.
