An adjective for “grey” derived from primitive ᴹ✶thindi (Ety/THIN) because primitive final vowels vanished in Ilkorin.
Doriathrin
thind
masculine name. Thind
thind
adjective. grey
hedhu
adjective. grey
A Doriathrin adjective for “grey” written heðu in The Etymologies, and derived from the primitive form ᴹ✶khithwa [kʰitʰwa] (Ety/KHIS). This word illustrates several interesting phonetic changes in Ilkorin.
The [[ilk|[i] became [e] before the final [a]]].
Both the aspirates became voiceless spirants: [kʰ-] > [x-] and [-tʰ-] > [-θ-].
Later the [[ilk|initial [x-] became [h-]]].
Meanwhile the [[ilk|medial [-θ-] voiced to [-ð-]]] (“dh”).
The [[ilk|primitive final [a] was lost]].
Afterwards, the resulting [[ilk|final [w] became [u]]].
In most other Doriathrin words, a [[ilk|final [u] from [w] further developed into [o]]]; it is unclear why this change did not occur here.
lûn
adjective. pale
A Doriathrin adjective for “pale” derived from primitive ᴹ✶lugni, a revision of the form luin that appeared in The Etymologies as published in The Lost Road (Ety/LUG², EtyAC/LUG²). The revision of [ui] >> [ū] probably reflects Tolkien’s vacillation on how primitive [[ilk|[g] vocalized before [m], [n]]] in Ilkorin. The earlier form of this word might an element in the name Draugluin “Werewolf” (LR/134), which in earlier writings was glossed “Werewolf Pale” (LB/205). The early Noldorin word ᴱN. lhui “pale” might be a precursor to it (PE13/149).
A shorter Ilkorin name for Ilk. Thingol appearing in The Etymologies from the 1930s (Ety/THIN). It is simply thind “grey” used as a name.
