'axiomatize' originates from Modern English, specifically formed from the noun 'axiom' plus the verb-forming suffix '-ize', where 'axiom' derives from Greek 'axiōma' meaning 'that which is thought fit or worthy' and the root 'axios' meant 'worthy'.

'axiomatize' developed by combining English 'axiom' (from Latin/Greek 'axioma') with the productive English/Greek-derived suffix '-ize'; Greek 'axiōma' passed into Latin as 'axioma', then into English as 'axiom', and later gave rise to the verb form 'axiomatize' in modern English.

Initially, the root 'axioma' meant 'a self-evident principle or that which is thought worthy'; over time the derived English verb came to mean 'to make something into (or express as) a system of axioms' or 'to formalize by axioms'.
