'disembody' originates from the prefix 'dis-' meaning 'apart' and the word 'embody', which comes from the Old French 'embodier', meaning 'to give a body to'.

'embodier' transformed into the English word 'embody', and with the addition of the prefix 'dis-', it became 'disembody'.

Initially, it meant 'to remove from a body', and this meaning has largely remained the same in modern usage.
