'improperly-answered' originates from the combination of 'improperly' and 'answered', where 'improperly' is derived from Latin 'improprius', meaning 'not proper', and 'answered' is the past participle of 'answer', from Old English 'andswaru', meaning 'a response'.

'improperly' changed from the Latin 'improprius' to the Middle English 'improper', and 'answered' evolved from Old English 'andswaru' to the modern English 'answer'.

Initially, 'improperly' meant 'not proper', and 'answered' meant 'a response'. Over time, 'improperly-answered' evolved to mean 'answered in a manner that is not correct or suitable'.
