Ilk. dunn adj. “black” (Category: Black)
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).
