means To correct grammar, punctuation, spelling, and consistency in a piece of writing before it's published.

from A straightforward compound of 'copy' (text prepared for printing — a sense going back to print shops and newspaper offices) and 'edit' (to prepare for publication, from Latin 'editus,' put forth). The job and term solidified with the rise of the modern newspaper and publishing industries, where someone had to stand between the writer's draft and the printed page, catching errors before they became permanent in ink.
