hedhu
adjective. greyA 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.
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.
