An archaic noun for “polished metal” in The Etymologies of the 1930s under the root ᴹ√RUS “flash, glitter of metal” that was “chiefly found in names” like N. Maidhros “Pale-glitter” (Ety/RUS). In Tolkien’s later writings the second element of Maedhros or Maedros was S. ross “red-haired”, so this 1930s word was probably abandoned. However there is a hint Tolkien may have still been considering it in the gloss “Star-glitter” for the name Elros from the Quendi and Eldar essay of 1959-60 (WJ/414); elsewhere Elros was usually translated “Star-foam” (Let/448; PM/349).
Neo-Sindarin: If you do decide to use this word, it should be adapted as ᴺS. ross “polished metal” since in Noldorin of the 1930s initial r unvoiced to rh, but this was not the case for Sindarin of the 1950s and 60s.
