A noun for “wolf” in The Etymologies of the 1930s derived from the root ᴹ√ÑGARAM (Ety/ÑGAR(A)M).
Conceptual Development: This word seems to have replaced N. araf or aram derived from the rejected root ᴹ√ƷARAM with various glosses like “wolf” or (small or swift) “dog” (Ety/ƷARAM; EtyAC/ƷARAM). This in turn may be a later iteration of G. harog or harw “wolf” from the Gnomish Lexicon of the 1910s with feminine variant G. harach “a she-wolf” (GL/48).
A transient name for Keleborn appearing in the Lord of the Rings drafts from the 1940s (TI/256). Roman Rausch suggested it might be a combination of aran “king” and a variant form of fein “white” (EE/2.34).
