'adempt' originates from Latin, specifically the word 'ademptus', where 'ad-' meant 'toward' and 'emere' meant 'to take'.

'ademptus' transformed into the English word 'adempt', and eventually became the modern English word 'adempted' as its past participle form.

Initially, it meant 'to take away or revoke', and this meaning has largely remained the same in modern usage.
