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

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

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