How to say "amendment" in Japanese

Choosing the right word
  • 修正しゅうせいJLPT N3approx.Common
    noun, suru verb, transitive verbThe general-purpose word for amending or revising a text, plan, or piece of work to correct or improve it; choose this unless a law or formal rule is what is being amended.
    失礼しつれいですが御ご提案ていあんを修正しゅうせいさせていただきます。↗
    I beg to modify your proposal.
  • 改正かいせいJLPT N2approx.Common
    suru verb, transitive verb, no-adjectiveThe word for amendment in the legal sense — revising a law, regulation, or other formal rule. When 'amendment' means a change made to legislation or a constitution, this is the word.
    時刻表じこくひょうが改正かいせいされた。↗
    The timetable has been revised.
  • 訂正ていせいJLPT N1approx.Common
    suru verb, transitive verb, no-adjectiveReally a word for correcting mistakes — fixing errors in a text, figure, or statement. It fits 'amendment' only when the change amounts to fixing an error; otherwise 修正 or 改正 is what you want.
    間違まちがっていれば私のつづりを訂正ていせいしてください。↗
    Correct my spelling if it's wrong.
  • 変更へんこうJLPT N3approx.Common
    noun, suru verb, transitive verbThe neutral word for changing or altering something — a plan, schedule, or arrangement. As 'amendment' it suits cases where details are simply changed, with no implication of correcting an error or revising a law.
    その規則きそくは絶対ぜったい変更へんこうできない。↗
    The rule is utterly inflexible.

Use 修正 for amending or correcting documents and work in general, 改正 for amending laws and formal rules, 訂正 only when fixing outright errors, and 変更 for simply changing details.
