malefactor

The word 'malefactor' is a direct borrowing from Latin malefactor, itself formed from male ('badly') and factor ('a doer'). Its literal meaning, 'an evildoer', has remained remarkably consistent from its classical origins to modern English. The logic is transparent: it combines the concept of wrongful action with the agent who performs it. This construction follows a common Latin pattern for forming agent nouns that describe a person by their characteristic action, in this case, the doing of bad deeds.

Structure: male (bad) + factor (maker) - male: From Latin male, meaning 'badly' or 'ill'. It functions as a negative prefix in this compound. - factor: From Latin factor, meaning 'a maker' or 'a doer', from the verb facere ('to make' or 'to do'). It functions as the core noun-forming element.
