Etymology

It is borrowed from Ancient Greek κριτήριον (kritḗrion, “a means of judging, test, standard”),[2][3][4][5][6] from κριτής (kritḗs, “judge”),[2][3][4][7] from κρίνω (krī́nō, “to separate, decide, judge”).[5][7][8][9] Dictionary.com analyses the Greek noun as the stem of the verb with a neuter suffix naming a means, akin to Latin -tōrium, the source of -tory.[10] Etymonline and Wiktionary take the English word through a Latinized form, New Latin criterion,[11][1] and Etymonline traces the Greek verb to Proto-Indo-European *krei- (“to sieve”), hence "to discriminate, distinguish".[11][5] In the 17th century the word was often written in Greek letters;[2][3] Barnhart records it in Latin letters from 1661, and a Latinized form criterium from before 1631, in Donne, which was used now and then until the late 19th century.[3] It is related to critic, critical and crisis.[7][3][1]

Earliest recorded meaning

A distinguishing mark or feature by which a thing can be judged: 1613, in T. Jackson's Eternall Truth of Scriptures, a sense the OED marks obsolete after 1678.[2] Etymonline dates its use as a Greek word in English to the 1610s, and the naturalized word to the 1660s.[11]

Semantic evolution

The main modern sense, a test, rule or standard by which something is judged, is recorded from 1622, in a sermon by Bishop Joseph Hall,[2][12] and Dictionary.com dates the word to 1605–15.[10] From 1647 to 1678 it could also mean the faculty or organ of judging, in Henry More's Philosophicall Poems.[2] Johnson (1755) defined it as a mark by which anything is judged of with regard to its goodness or badness.[13] In philosophy the word also names a defining characteristic of something,[8] and Webster's Third gives "a characterizing mark or trait" as its first sense.[9] The Greek plural criteria has remained the usual one, beside the rarer criterions.[5][12][1]

Usage notes
