Etymology

A post-classical Latin female form of classical Latin motor (“motor”). It is used as the feminine form of motor (“(he) that moves”) in neo-Latin, as in the original of Newton's Laws of Motion: proportionalem esse vi motrici impressae ‘is proportional to the motive force applied’ formed on the agentive suffix: -tor (masculine) / -trix (feminine).
