'unethically-performed' originates from the prefix 'un-' meaning 'not,' combined with 'ethical,' derived from Greek 'ethikos,' and 'perform,' from Old French 'parfornir,' meaning 'to complete.'

'unethically' evolved from 'unethical,' which was formed by adding the prefix 'un-' to 'ethical.' 'Performed' comes from the Old French 'parfornir,' which became 'perform' in Middle English.

Initially, 'perform' meant 'to complete or carry out,' while 'unethical' meant 'not conforming to moral standards.' The combination 'unethically-performed' emphasizes actions done without ethical consideration.
