'allegorism' originates from Greek, specifically the word 'allēgoria,' where 'allos' meant 'other' and 'agoreuein' meant 'to speak in public.'

'allēgoria' transformed into the Latin word 'allegoria,' and eventually became the modern English word 'allegory' through Old French.

Initially, it meant 'to speak in a way that conveys a hidden meaning,' but over time it evolved into its current meaning of 'interpreting texts or artworks as allegories.'
