There are more words but they are from Tolkien's earlier conceptional periods. Tolkien likely changed these words as he evolved the aesthetics and completeness of the languages. You may even find languages that Tolkien later rejected. Do not mix words from different time periods unless you are familiar with the phonetic developments.
ñgaram
root. *wolf
darak
root. *wolf
A root in The Etymologies of the 1930s with derivatives ᴹQ. ráka/N. draug “wolf” (Ety/DARÁK), the latter an element in the name N. Draugluin “[Blue] Werewolf” (LR/134), originally “Werewolf Pale” (LB/205). The continued appearance of this name in later versions of the Silmarillion imply the continued validity of this root.
Below: Tolkien's Late Period (1950–1973). These are from Tolkien's late conceptual period — his most settled forms of the languages. Prefer these over the earlier ones above when composing new text.
An unglossed root in The Etymologies of the 1930s with various derivative “wolf” words like ᴹQ. narmo and N. garaf (Ety/ÑGAR(A)M). It replaced a rejected root ᴹ√ƷARAM of the same meaning (Ety/ƷARAM). Unlike other wolf words, this root seems to be more neutral, without the “evil” connotations of words like S. gaur “werewolf”.
