criticize v.

formerly critick, 1580s, "one who passes judgment, person skilled in judging merit in some particular of things," from French critique (14c.), from Latin criticus "a judge, a censor, an estimator," also "grammarian who detects spurious passages in literary work," from Greek kritikos "able to make judgments," from krinein "to separate, decide" (from PIE root *krei- "to sieve," thus "discriminate, distinguish"). The meaning "one who judges merits of books, plays, etc." is from c. 1600. The English word always has had overtones of "censurer, faultfinder, one who judges severely."

To understand how the artist felt, however, is not criticism; criticism is an investigation of what the work is good for. ... Criticism ... is a serious and public function; it shows the race assimilating the individual, dividing the immortal from the mortal part of a soul. [George Santayana, "The Life of Reason," 1906]

A perfect judge will read each work of wit

With the same spirit that its author writ;

For "inferior or incompetent critic" 17c. had criticaster; later generations used criticling, critikin, criticule.

word-forming element used to make verbs, Middle English -isen, from Old French -iser/-izer, from Late Latin -izare, from Greek -izein, a verb-forming element denoting the doing of the noun or adjective to which it is attached.

The variation of -ize and -ise began in Old French and Middle English, perhaps aided by a few words (such as surprise, see below) where the ending is French or Latin, not Greek. With the classical revival, English partially reverted to the correct Greek -z- spelling from late 16c. But the 1694 edition of the authoritative French Academy dictionary standardized the spellings as -s-, which influenced English.

In Britain, despite the opposition to it (at least formerly) of OED, Encyclopaedia Britannica, the Times of London, and Fowler, -ise remains dominant. Fowler thinks this is to avoid the difficulty of remembering the short list of common words not from Greek which must be spelled with an -s- (such as advertise, devise, surprise). American English has always favored -ize. The spelling variation involves about 200 English verbs.

chiefly British English spelling of criticize; for suffix, see -ize. Related: Criticised; criticising.
