'wrongly-executed' originates from the combination of 'wrongly' and 'executed'. 'Wrongly' comes from Old English 'wrang', meaning 'twisted' or 'crooked', and 'executed' from Latin 'executus', past participle of 'exsequi', meaning 'to follow out'.

'wrongly-executed' combines the adverb 'wrongly' with the past participle 'executed', forming a compound adjective in modern English.

Initially, 'wrongly' meant 'in a wrong manner', and 'executed' meant 'carried out'. Together, they evolved to mean 'carried out incorrectly'.
