Word Originlate Middle English: from Latin reducere, from re- ‘back, again’ + ducere ‘bring, lead’. The original sense was ‘bring back’ ; this led to ‘bring to a different state’, then ‘bring to a simpler or lower state’ (hence sense (2)); and finally ‘diminish in size or amount’ (sense (1), dating from the late 18th cent.).
