[Alteration (with th influenced by authentic, since an authentic document or source is one emanating from its author or reflecting an author's views) of Middle English auctour, autor, from Anglo-Norman, from Latin auctor, creator, from auctus, past participle of augēre, to create; see aug- in the Appendix of Indo-European roots.]

au·thori·al (ô-thôrē-əl, ô-thŏr-) adj.

Usage Note: The verb author was once criticized as an unnecessary or pretentious synonym of write. Nowadays, many people aren't aware of this usage proscription at all, and the Usage Panel's sympathy for the traditional view has eroded over the decades. In 1964, 81 percent of the Panel found using author as a verb unacceptable in writing. In our 1988 survey, 74 percent of the Panel rejected it in the sentence He has authored a dozen books on the subject. In 2001, 60 percent of the Panel rejected it, and in 2017, only 34 percent did. · Journalists frequently use the verb author to apply to the creation or sponsoring of legislative acts, as in The senator authored a bill limiting uses of desert lands in California. In these cases the lawmaker may not have actually written the bill bearing that lawmaker's name but rather promoted its idea and passage. The Panelists continue to be even more tolerant of this legislative usage: 64 percent rejected this sentence in 1988, 51 percent in 2001, and only 27 percent in 2017.
