To go through an official document before it is shown to the public and take out the parts that must stay secret — names, addresses, anything that would put someone in danger or break a rule. In practice this usually means covering the words with thick black bars, so what remains is a page of ordinary text with black stripes through it. You redact a document, or you redact the information itself: 'the names were redacted'. The past participle is used constantly as an adjective — 'a redacted report', 'heavily redacted'. This is a formal word from law, government and journalism, not everyday speech; a student will meet it in the news. There is an older, quite different meaning that you may still see in academic writing about texts: to edit or prepare a piece of writing for publication, putting material into its final form. That sense is now rare outside scholarship, and if you say 'redact' today people will assume you mean the black bars.
（公文公開前）遮蔽、塗黑、刪節機密內容；新聞上常見的「打碼、塗黑」就是這個動作。舊義另有「編輯、整理成書」，現多見於學術用法。
組成From Old French redacter, from Latin redactus, the perfect passive participle of redigō 'drive back, lead back, collect, reduce', which is re- 'back' + agō 'put in motion, drive'. So the old idea is 'driving something back into shape' — reducing a mass of material to a fixed form. It is a piecewise doublet of react.
