'axiomatize' originates from Modern English, ultimately formed from Greek 'axiōma' via Latin/French influence and the verb-forming suffix '-ize' (from Greek '-izein').

'axiomatize' changed from the noun 'axiom' (from Late Latin/Medieval Latin 'axioma') with the addition of the productive English suffix '-ize', producing the verb 'axiomatize' and later the adjective/past form 'axiomatized'.

Initially related to the noun 'axiom' meaning 'that which is thought worthy' or 'self-evident principle', it evolved into the verb sense 'to make into axioms' and the adjective/past form meaning 'made into axioms' or 'expressed as axioms'.
