'disestablish' originates from the prefix 'dis-' meaning 'apart' or 'away' and the word 'establish' from Old French 'establir', which meant 'to set up'.

'establir' transformed into the Middle English word 'establishen', and eventually became the modern English word 'establish'.

Initially, it meant 'to set up or found', but with the prefix 'dis-', it evolved to mean 'to remove the status of being established'.
