Word Originlate 16th cent.: from medieval Latin actuat- ‘carried out, caused to operate’, from the verb actuare, from Latin actus ‘event, thing done’, act- ‘done’, from the verb agere, reinforced by the French noun acte. The original sense was ‘carry out in practice’, later ‘stir into activity, enliven’; sense (1) dates from the mid 17th cent.
