-hay (also hays, hayes, etc.) is a place-name word-ending common in England. It derives from the Old English word hege or haga, Middle English heie, in Icelandic hagi, meaning "an enclosed field", and is from the same root as the English word "hedge", a structure which surrounds and encloses an area of land, from the Norman-French haie, "a hedge". Haw (from O.E. haga) and Hay (from O.E. hege) are cognate and both mean "hedge".
