A word for “dog” appearing in 1968 notes on monosyllabic primitive Elvish nouns (VT47/35). Of the primitive forms, Tolkien first gave ✶wā(w) “dog” and ✶grā “bear”, but ✶wā(w) was struck through and the gloss of ✶grā was changed to “dog”, after which Tolkien wrote Q. roa “dog” (VT47/36). He seems to have been disatisfied with this derivation, however, going on to write a number of primitive animal roots in the upper margin, including ✶yarr- “dog”.

Conceptual Development: ᴱQ. roa “a wild beast” appeared in the Qenya Lexicon of the 1910s, derived from primitive ᴱ✶raw̯a under the early root ᴱ√RAVA or ᴱ√RAẆA (QL/79).

Neo-Quenya: Giving Tolkien’s vacillations on these 1968 forms, I’d stick to the better known ᴹQ. huo as the common word for “dog” in (Neo) Quenya, which is the word used in Helge Fauskanger’s Neo-Quenya New Testament (NQNT).
