Etymology: "Ducts" is the plural of "duct," and the original idea is simply leading. The Latin "ductus" meant "leading" or "conducting," formed from the verb "dūcō," "to lead, conduct, draw," plus a suffix that turns an action into a noun. The term was borrowed into English directly from Latin, so it kept the sense of something along which things are guided. Medieval Latin narrowed that sense to a conveyance of water, a channel carrying a flow, and English inherited that practical meaning. Over time the word spread from water channels to passages for air, fluids and other materials in buildings, bodies and machines. "Duct" is also a doublet of "ductus" and "douit," meaning that these forms all descend from the same Latin source but reached English by different routes. The word thus shows the same Latin verb working its way into English more than once.
