duct

Definition

A pipe, tube or canal which carries gas or liquid from one place to another.

Etymology

Borrowed from Latin ductus (“leading, conducting”, noun), from dūcō (“to lead, conduct, draw”) + -tus (action noun suffix). Doublet of ductus and douit. Also via Medieval Latin ductus (“a conveyance of water; a channel”), which itself has the first mentioned etymology.
