The suffix -ize added to a word turns it into

A transition word

Explanation:

a verb-forming suffix occurring originally in loanwords from Greek that have entered English through Latin or French (baptize; barbarize; catechize); within English, -ize is added to adjectives and nouns to form transitive verbs with the general senses “to render, make” (actualize; fossilize; sterilize; Americanize), “to convert into, give a specified character or form to” (computerize; dramatize; itemize; motorize), “to subject to (as a process, sometimes named after its originator)” (hospitalize; terrorize; galvanize; oxidize; simonize; winterize). Also formed with -ize are a more heterogeneous group of verbs, usually intransitive, denoting a change of state (crystallize), kinds or instances of behavior (apologize; moralize; tyrannize), or activities (economize; philosophize; theorize).
