noun. wolf

A noun for “wolf” in The Etymologies of the 1930s derived from primitive ᴹ✶d’rāk under the root ᴹ√DARAK (Ety/DARÁK), where the ancient initial *dr* became *r* as usual for Quenya (PE19/37).

Conceptual Development: Earlier words for “wolf” of similar form include ᴱQ. ulku and feminine ᴱQ. ulqi “she-wolf” appearing in the Qenya Lexicon of the 1910s under the early root ᴱ√ULUKU (QL/97).
