gourmandize v.

late 15c., gourmaunt, "glutton," from Old French gormant "glutton," originally an adjective, "gluttonous," a word of uncertain origin. Not considered to be connected with gourmet. Meaning "one fond of good eating" is from 1758.

The gourmand is one whose chief pleasure is eating; but a gourmet is a connoisseur of food and wines. In England the difference is this: a gourmand regards quantity more than quality, a gourmet quality more than quantity. [Brewer, "Dictionary of Phrase and Fable," Philadelphia, 1898]

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.
