'axiomatization' originates from modern English, specifically formed from the verb 'axiomatize' plus the noun-forming suffix '-ation'; 'axiomatize' itself derives from the noun 'axiom' (from Greek 'axiōma').

'axiomatization' was formed in English from 'axiomatize' (to make axiomatic), which in turn came from 'axiom' (from Greek 'ἀξίωμα' / 'axiōma') via Late Latin/Old French routes; the suffix '-ize' comes ultimately from Greek '-ίζειν' through Latin/French, and '-ation' is a common noun-forming suffix in English.

Initially, the root 'axiom' meant 'that which is thought worthy or self-evident'; over time the related verb and noun forms shifted to mean 'to make something into a set of axioms' and the current noun 'axiomatization' denotes that process.
