Mid 17th century (in the sense 'course' or 'direction'): from Latin ductus 'leading, aqueduct' from duct- 'led', from the verb ducere.

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’.

Rhymes

Couple this case with a Zalman ducted CPU fan, and overall fan noise can be kept to a minimum. The windows don't open and the air is filtered and ducted. This appeared to carry water ducted from the hills north of the site, where North Farm now stands, to either the village or the manor house. Origin Mid 17th century (in the sense ‘course’ or ‘direction’): from Latin ductus ‘leading, aqueduct’ from duct- ‘led’, from the verb ducere.
