'allegorize' originates from the Greek word 'allēgorein', where 'allos' meant 'other' and 'agoreuein' meant 'to speak in public'.

'allēgorein' transformed into the Latin word 'allegoria', and eventually became the modern English word 'allegorize' through Middle English.

Initially, it meant 'to speak figuratively', but over time it evolved into its current meaning of 'to represent as an allegory'.
