'allegeable' originates from the Latin word 'allegare,' where 'ad-' meant 'to' and 'legare' meant 'to send or commission.'

'allegare' transformed into the Old French word 'alegier,' and eventually became the modern English word 'allege' through Middle English.

Initially, it meant 'to send or commission,' but over time it evolved into its current meaning of 'to assert or claim.'
