Q. sarnië n. “shingle, pebble bank” (Category: Rock, Stone)
A noun for a “shingle, pebble bank” in The Rivers and Beacon-hills of Gondor from the late 1960s from primitive ✶sarniye, also the basis for the river name S. Serni (VT42/11). It is clearly an abstract noun formation based on Q. sar (sarn-) “(small) stone”. Here the gloss “shingle” is used in the sense of a mass of smell pebbles rather than as a roofing tile.
