Etymology: Waterhorse is a plain compound: "water" joined to "horse," a creature imagined as a horse living in water. The pairing is transparent, so the interest lies in the myth it names rather than in any hidden sound change or shifted sense. Across the British Isles and Scandinavia, stories of horse-shaped water spirits that lure travellers or drown them appear in local folklore, and the compound describes exactly that picture. The word itself is built from two plain English elements that have been combined in the language for centuries, and English speakers can read the meaning straight off the parts. The creature belongs to the same family of tales as the Scottish kelpie and the Irish each-uisge, though "waterhorse" is the English compound that describes the shared idea in everyday terms.
