vandalize v.

1660s, "willful destroyer of what is beautiful or venerable," from Vandals, name of the Germanic tribe that sacked Rome in 455 under Genseric, from Latin Vandalus (plural Vandali), from the tribe's name for itself (Old English Wendlas), perhaps from Proto-Germanic *wandljaz "wanderer." The literal historical sense in English is recorded from 1550s.

There does not seem to be in the story of the capture of Rome by the Vandals any justification for the charge of willful and objectless destruction of public buildings which is implied in the word 'vandalism.' It is probable that this charge grew out of the fierce persecution which was carried on by [the Vandal king] Gaiseric and his son against the Catholic Christians, and which is the darkest stain on their characters. [Encyclopaedia Britannica, 13th ed., 1926]

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.
