'archaize' originates from English formation based on the adjective 'archaic', ultimately from Latin 'archaicus' and Greek 'arkhaios', where 'arkhaios' meant 'ancient'.

'archaize' developed in Modern English by adding the productive suffix '-ize' to 'archaic' (from Middle French 'archaïque' and Latin 'archaicus', from Greek 'arkhaios'), creating a verb meaning 'to make archaic'.

Initially, it meant 'to render or make something ancient/old-fashioned', and this basic sense has been retained into modern usage as 'to make archaic or adopt archaic forms'.
