Adding -ize to a Noun or Adjective
The suffix -ize has been productive in English since the time of Thomas Nashe (1567–1601), who claimed credit for introducing it into English to remedy the surplus of monosyllabic words. Almost any noun or adjective can be made into a verb by adding -ize <hospitalize> <familiarize>; many technical terms are coined this way <oxidize> as well as verbs of ethnic derivation <Americanize> and verbs derived from proper names <bowdlerize> <mesmerize>. Nashe noted in 1591 that his -ize coinages were being criticized, and to this day new words ending in -ize <finalize> <prioritize> are sure to draw critical fire.
