A word in the Declension of Nouns from the early 1930s with stem form hun- and gloss “earth” (QL/39). It might be a later iteration of ᴱQ. han “ground, earth” from the Qenya Lexicon of the 1910s (QL/39), and if so then hún might also be used as “✱ground”. I think it is useful to assume so for purposes of Neo-Quenya, as the other attested word for “ground”, Q. talan, is probably used more often for “floor”, including floors above the ground level.
Qenya
húna-
verb. to howl
hún
noun. earth, earth, *ground
The deleted verb ᴹQ. hūna- “howl” appeared in The Etymologies of the 1930s under the deleted root ᴹ√ÑO, replacing ñōna- “groan” (EtyAC/ÑŌ²).
Neo-Quenya: Since the root ᴹ√ÑO seems to have become √ÑGAW “howl”, I would revise this verb to ᴺQ. nauna- for purposes of Neo-Quenya.
