Etymology: The name is a compound of two Latin words that seem to contradict each other. "Mergus" meant a diver, from "mergere," to dip or plunge under water, and "anser" meant goose. So the name literally means "diving goose," even though these birds are ducks. Ancient Latin writers used "mergus" for a diving water bird, probably not the same species, and naturalists later applied it to the genus. "Anser" is a cognate of English "goose," since both descend from a common Indo-European root. The bird's name thus pairs a Latin verb of diving with a word that is also the ancestor of "goose" in a sense. The standard English spelling is "merganser," and the term came into use in scientific writing rather than everyday speech.
