'allow' originates from Old French, specifically the word 'alouer,' where 'a-' meant 'to' and 'loer' meant 'praise or approve.'

'alouer' transformed into the Middle English word 'allowen,' and eventually became the modern English word 'allow.'

Initially, it meant 'to praise or approve,' but over time it evolved into its current meaning of 'to permit or give permission.'
