[-ize] vb suffix [ME -isen, fr. OF -iser, fr. LL -izare, fr. Gk -izein] 1 a (1): cause to be or conform to or resemble "systemize" "Americanize": cause to be formed into "unionize" (2): subject to a (specified) action "plagiarize" (3): impregnate or treat or combine with "aluminize" b: treat like "idolize" c: treat according to the method of "bowdlerize"
2. a: become: become like "crystallize" b: be productive in or of "hypothesize": engage in a (specified) activity "philosophize" c: adopt or spread the manner of activity or the teaching of "Platonize" usage 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 coinages in -ize were being complained about, and to this day new words in -ize "finalize" "prioritize" are sure to draw critical fire.
