Origin

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 century).

  • duct from mid 17th century:

    Duct comes from Latin ductus meaning both ‘leading’ and ‘aqueduct’ formed from ducere ‘to lead’. The verb has produced numerous words in English including abduct (early 17th century) to lead away; conduct (Middle English) lead with; conduit (Middle English); deduce (Late Middle English) draw a conclusion from something; duke; educate (Late Middle English) ‘lead out’; induce (Late Middle English) lead in; introduce (Late Middle English) bring into (a group etc); produce (Late Middle English) ‘lead forward’; reduce (Late Middle English) bring back; seduce (Late Middle English) lead away (originally from duty, with the sexual sense developing in the M16th); subdue (Late Middle English) ‘draw from below’.

Origin

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