The story
- Scottish Gaelic · derived fromcailpeach
- English todaykelpie
Possibly from Scottish Gaelic cailpeach or colpach, meaning "colt"; recorded earliest in a placename (Kelpie hoall, Kirkcudbrightshire) in 17th century. The dog breed, from 1889, derives from the name shared by the first two breeding bitches (dam and pup) in Victoria, Australia, which in turn derives from the mythological spirit.
