'uncompelled' originates from the prefix 'un-' meaning 'not' and the word 'compelled' from Latin 'compellere', where 'com-' meant 'together' and 'pellere' meant 'to drive'.

'compellere' transformed into the Old French word 'compeller', and eventually became the modern English word 'compel', with 'un-' added to form 'uncompelled'.

Initially, 'compel' meant 'to drive together', but over time it evolved into its current meaning of 'to force or oblige'. 'Uncompelled' retains the negation of this meaning.
