派生 reducer noun 语源
late Middle English: from Latin reducere, from re- 'back, again' + ducere 'bring, lead'. The original sense was 'bring back' (hence 'restore', now surviving in sense 5); this led to 'bring to a different state', then 'bring to a simpler or lower state' (hence sense 3); and finally 'diminish in size or amount' (sense 1, dating from the late 18th cent.)
