Etymology: The word "ducting" is simply the gerund of "duct", so its history is that of the root. "Duct" was borrowed from Latin "ductus", meaning "leading" or "conducting", a noun formed from "dūcō", "to lead, conduct, draw". Latin "ductus" carried the sense of leading or guiding in its original form, and the word's sense of a channel for conveying material came later, through Medieval Latin, where "ductus" could mean a conveyance of water or a channel. That shift is the interesting part: a word about the act of leading became a word for the pipe or passage that does the leading. English "duct" keeps both senses, so when "ducting" names the network of enclosed passages carrying air through a building, it inherits a channel meaning built on the verb "to lead".
