Etymology

Origin of duct

First recorded in 1640–50; from Latin ductus “conveyance (of water),” hence “channel” (in Medieval Latin ), equivalent to duc- (variant stem of dūcere “to lead”) + -tus suffix of verbal action

Explanation

A duct is a pipe, tube, or tunnel through which water can flow. If there's a leaking duct in your kitchen, you may need to patch it or replace it — in any event, you should probably call a plumber. Liquids can move through a duct, and when the duct is in a person's body, like a tear duct or a pancreatic duct, it has the same purpose — tears, for example, flow through tear ducts. Some ducts aid the flow of substances other than liquids, like the air ducts that blow warm air from your furnace into the rooms of your house. Duct tape, often incorrectly called "duck tape," is tape that's used for repairing ducts.
