2、edit:  Etymologically, someone who edits a newspaper ‘gives it out’, or in effect ‘publishes’ it. And that in fact is how the word was first used in English: when William Enfield wrote in his 1791 translation of Brucker’s Historia critica philosophiae that a certain author ‘wrote many philosophical treatises which have never been edited’, he meant ‘published’.This usage comes directly from ēditus, the past participle of Latin ēdere ‘put out, exhibit, publish’, which was a compound verb formed from the prefix ex- ‘out’ and dare ‘put, give’ (source of English date, donate, etc). In its modern application, ‘prepare for publication’, it is mainly a back-formation from editor , which acquired this particular sense in the 18th century. (French éditeur still means ‘publisher’, and the term editor is used in that sense in some British publishing houses.)=> date, donate
