-hay (also hays, hayes, etc.) is a place-name word-ending common in England. It derives from the Old English word hege[1] or haga,[2]Middle Englishheie,[3] in Icelandichagi,[2] 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,[4] from the Norman-French haie, "a hedge".[5] Haw (from O.E. haga) and Hay (from O.E. hege) are cognate and both
mean "hedge".[3]
