'unlimit' originates from the prefix 'un-' meaning 'not' and the word 'limit' from Latin 'līmitāre', meaning 'to bound or confine'.

'unlimit' was formed by adding the prefix 'un-' to the word 'limit', which came from the Latin 'līmitāre'.

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