ᴱ√YAÐA root. “*gloom”
An unglossed root in the Qenya Lexicon of the 1910s with Gnomish form gadh- and derivatives ᴱQ. yanda “dark, gloomy” and ᴱQ. yara “a gloom, blight, lowering darkness” (QL/105). In the contemporaneous Gnomish Lexicon Tolkien gave the primitive form ᴱ✶ı̯ādh (GL/37). This root was the basis for the 1910s names ᴱQ. Aryan/G. Garioth/ᴱIlk. Aryador “Land of Shadow”. In The Etymologies of the 1930s, the last of these became Ilk. Ariador “Land Outside [Doriath]” (Ety/ELED, GAT(H)), before the name was abandoned entirely.
