An unglossed word in 1964 notes on Dalath Dirnen (DD) derived from the root √PHAW (PE17/181). Since this root was elsewhere glossed “emit (foul breath etc.)”, this word probably mean something like “✱breath, puff of breath”, like its cognate Q. foa (VT47/35).

An adjective for “thirsty” appearing in names like Anfauglir “Jaws of Thirst”.
Conceptual Development: In the Gnomish Lexicon of the 1910s the word for “thirsty” was G. luib (GL/55) clearly based on the early root ᴱ√LOYO (QL/56). By Early Noldorin Word-lists of the 1920s, the word had become ᴱN. faug “thirsty” (PE13/143), and N. faug “thirsty” appeared in The Etymologies of the 1930s under the root ᴹ√PHAU̯ “gape” (Ety/PHAU). Christopher Tolkien gave faug the gloss “gape” in The Silmarillion appendix (SI/faug), but that seems to refer to the root meaning from the 1930s.
