'archaize' originates from the adjective 'archaic' combined with the verbalizing suffix '-ize'. 'Archaic' ultimately comes from Greek 'arkhaios' meaning 'ancient'.

'archaize' formed in English by attaching the suffix '-ize' (from Greek '-izein' via Latin and Old French) to the adjective 'archaic', which itself came into English from Latin/French forms of Greek 'arkhaios'.

Initially related to the Greek root meaning 'ancient', the formation 'archaize' has meant 'to make (something) appear ancient or old-fashioned' and retains that sense in modern usage.
