'bandon' originates from Old French, specifically the word 'bandon', where 'ban' meant 'proclamation' or 'power to command'.

'bandon' passed into Middle English from Old French 'bandon' and was used in medieval texts to mean jurisdiction or an official proclamation; over time the specific form 'bandon' fell out of common use in Modern English.

Initially it meant 'proclamation' or 'jurisdiction', but over time it became archaic; related senses survived in words like 'ban' (prohibition) while 'bandon' itself largely fell out of regular usage.
