'unlawfully-asserted' originates from the combination of 'unlawful' and 'assert,' where 'unlawful' means 'not conforming to, permitted by, or recognized by law' and 'assert' means 'to state a fact or belief confidently and forcefully.'

'Unlawfully-asserted' combines the Middle English 'unlawful' and the Latin 'assertus,' which evolved into the modern English 'assert.'

Initially, 'assert' meant 'to state or declare,' and 'unlawful' meant 'not lawful.' The combination implies a declaration made without legal right.
