• Related修正しゅうせいNeutralThe everyday word for correcting mistakes or adjusting what is off; unlike 「加筆」 it need not add anything new. Common in 「加筆修正」.
• Related訂正ていせいWrittenWritten prose for putting mistakes right, as in 「訂正記事」; it corrects errors rather than adding polish the way 「加筆」 does.
• Related手直してなおしCasualColloquial for small changes to something mostly finished; closer to patching up than 「加筆」, which adds new material.
• Related改正かいせいNeutralFor revising laws and regulations, as in 「法改正」; do not use it for polishing a piece of writing the way 「加筆」 does.
• Related直しなおしCasualColloquial noun for correcting or mending, as in 「直しを入れる」; it covers repairs too, while 「加筆」 only adds to a work.
• Related補正ほせいWrittenWritten term for making up what is lacking or correcting errors, as in 「補正予算」; leans technical, unlike 「加筆」's literary additions.
• Related更正こうせいNeutralFor correcting errors in official filings or registrations; a procedural term, unrelated to improving a text as 「加筆」 is.
• Related改定かいていNeutralFor revising set things like prices or rules, as in 「料金改定」; never used for adding to a text the way 「加筆」 is.
• Related修訂しゅうていFormalFormal and rare, for correcting errors in books; a publishing term, centered on fixing mistakes rather than adding new material as 「加筆」 does.
• Related校訂こうていFormalFormal term for emending a text by comparing variant sources, mainly classical works; scholarly textual work, not 「加筆」-style adding.
• Related手を加えるてをくわえるNeutralIdiomatic phrase for working on something to fix or supplement it, by whatever means; covers the whole act, where 「加筆」 names the additions.
• Antonym削除さくじょNeutralThe opposite of 「加筆」: deleting or striking out parts of a text or data instead of adding and polishing.
• Antonym抹消まっしょうWrittenWritten prose for erasing records or striking entries off, cancelling rights; the opposite pole from 「加筆」's additions.

Use 「加筆」 for adding to or polishing an existing piece of writing or art, as in 「加筆修正」 or 「大幅に加筆」. To fix mistakes, choose 「修正」 (everyday) or 「訂正」 (written); for small tweaks to a finished work, 「手直し」. 「改正」 and 「改定」 are for laws, rules and prices, not texts; 「削除」 is the opposite — taking content away.
