A noun glossed “sward, turf” derived from √SAD “strip, flay, peel off” in notes on The Rivers and Beacon-hills of Gondor from 1967-69 serving as the second element of S. Calenhad “Green Space”, where Tolkien explained the abnormalities of the spelling by saying that that “dh” was generally represented as “d” in his maps (VT42/20).
