A Doriathrin adjective meaning “black” (Ety/DUN). Its Noldorin and Danian cognates imply development from a primitive form ✶dunnā. Since the primitive form ended in [a], the Ilkorin a*-affection]] would ordinarily have produced **donn. However, it seems that a-affection was prevented or reversed before [nn], as suggested by Helge Fauskanger (AL-Doriathrin/dunn).
ungoradjective. black, dark, gloomy
An adjective meaning “black, dark, gloomy” developed from the root ᴹ√UÑG (Ety/UÑG), perhaps from a primitive form ✶uñgrā̆* [uŋgrā̆] as suggested by Helge Fauskanger (AL-Ilkorin/ungor): after the [[ilk|primitive final [a] was lost]], the resulting [[ilk|final [r] would become syllabic and develop into [-or]]].
