duck / duck tape / duct tape
Is it duct or duck? One might think that duct tape is the original, used for sealing heating and ventilating ducts, and that the duck version formed as an eggcorn. But if so, one would most likely be mistaken. Duck tape appears to be the original. It’s definitely older than duct tape, but there is some question as to whether it formed from duck tape or was independently coined.
