Etymology

Old English wealhhnutu, literally "foreign nut," from Wealh "Welshman, foreigner" + hnutu "nut" — related to welsh

Word Origin

Long before walnut trees were introduced into England, they were cultivated for their tasty nuts in southern Europe. The nut tree native to the more northern areas of Europe was the hazel. In order to tell apart the native hazelnut and the less familiar walnut, Old English called the walnut wealhhnutu, which means "foreign nut." This word is a compound of wealh, "foreigner" and hnutu "nut." The Old English word wealh has supplied us with another word as well. While wealh meant "foreigner" in a general sense, it was applied specifically by the Anglo-Saxon invaders of Britain to the native people they found living on the island. Wealh gave rise to the modern forms Welsh, Welshman, and Welshwoman.
