A root appearing in several sets of etymological notes from 1957 glossed “warmth” and forming the basis for Q. árë “sunlight, warmth” (PE17/148). This is further supported by the archaic form †ázë for this word (LotR/1123), with intervocalic [s] > [z] > [r] as usual. The form Âs was also mentioned as an ancient name for the Sun in some Silmarillion notes (MR/380). At one point Tolkien connected this root to S. Asfaloth which he translated as “Sunlit Foam” (PE17/18); he then rejected this derivation saying the root form was actually √GAS, but since the ancient form was given as √AS in several other places, perhaps he changed his mind.
