ᴹ√MAD root. “*pale (yellow)”
A root in The Etymologies with derivatives ᴹQ. marya and N. maidh glossed “pale, fallow, fawn”(Ety/MAD), the last of these (fawn) probably referring to a light yellowish-tan color. In this entry it was the basis for the name N. Maidhros “Pale-glitter”, but this and related entries went through a number of revisions as Tolkien tried to sort out the origin of that name. Indeed in later writings Tolkien gave this name as S. Maedhros or Maedros along with completely different etymologies (PM/366; VT41/10). Nevertheless, I think it is worth retaining this root for purposes of Neo-Eldarin to refer to a pale yellow or tan color.
