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

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

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