'abase' originates from Old French, specifically the word 'abaissier,' where 'a-' meant 'to' and 'baissier' meant 'lower.'

'abaissier' transformed into the Middle English word 'abassen,' and eventually became the modern English word 'abase.'

Initially, it meant 'to lower or reduce in rank,' but over time it evolved into its current meaning of 'to humble or degrade.'
