Use 「過ち」 for a wrong one commits, often with a tone of remorse, as in 「過ちを犯す」. For everyday mistakes pick 「間違い」, for everyday slips 「ミス」, for negligence 「過失」, and for things simply not working out 「失敗」. The written terms 「失策」「失態」「誤謬」「錯誤」「過誤」 and the rare 「過怠」 each cover narrower ground, while 「ポカ」 and 「しくじり」 are casual. Antonyms: 「正しさ」, 「正解」.
