'adequately' originates from Latin, specifically the word 'adaequatus,' where 'ad-' meant 'to' and 'aequus' meant 'equal.' 'Answered' comes from Old English 'andswaru,' meaning 'a response or reply.'

'adequately' changed from the Latin 'adaequatus' to the Middle English 'adequat,' and eventually became the modern English word 'adequately.' 'Answered' evolved from Old English 'andswaru' to the modern English 'answered.'

Initially, 'adequately' meant 'equal to' or 'sufficient,' and 'answered' meant 'a response.' Over time, 'adequately-answered' evolved to mean 'sufficiently responded to.'
