sward

Sward sprouted from the Old English sweard or swearth, meaning "skin" or "rind." It was originally used as a term for the skin of the body before being extended to another surface—that of the earth's. The word's specific grassy sense dates back more than 500 years, but it rarely crops up in contemporary writing. The term, however, has been planted in a number of old novels, such as in this quote from Thomas Hardy's Tess of the d'Urbervilles: "The sun was so near the ground, and the sward so flat, that the shadows of Clare and Tess would stretch a quarter of a mile ahead of them...."
