gaurhoth
noun. group of werewolves
gaur
noun. werewolf
A noun for a “werewolf” (PE17/39; PE19/107; SA/gaur; Ety/ÑGAW), as opposed to a more ordinary wolf which would be [N.] garaf or draug. In The Etymologies of the 1930s, N. gaur was derived from the root ᴹ√ÑGAW “howl” (Ety/ÑGAW), and a similar derivation appeared in the Outline of Phonology (OP2) from the 1950s (PE19/106-107), but in notes on Words, Phrases and Passages from the Lord of the Rings (WPP) from the late 1950s or early 1960s, Tolkien said the meaning of its root was “falsify, deform, disguise” (PE17/39).
Conceptual Development: The first appearance of the word Gaurhoth (untranslated) was The Lay of Beleriand from the 1920s, already in reference to “Gaurhoth Ilse” as the home of Sauron the werewolf lord (LB/337).

The name of Tol Sirion after it was inhabited by Sauron and his minions, translated “Isle of Werewolves” (S/156), a combination of tol(l) “island”, the plural in of the definite article i and the class-plural of gaur “werewolf” using the suffix hoth “host” (SA/gaur, hoth).
Conceptual Development: In Silmarillion drafts from the 1930s, this name was Tol-na-Gaurhoth (SM/311, LR/284).
