Beware, older languages below! The languages below were invented during Tolkien's earlier period and should be used with caution. Remember to never, ever mix words from different languages!
oi
adverb. ever
oiakúma
place name. Oiakúma
oiolosse
place name. Everlasting Whiteness
oi-
verb. to live, pass one’s days
oia
adverb/adjective. everlasting
oiale
noun. everlasting age
oira
adjective. eternal
oire
noun. everlasting (?age), everlasting age
oio
noun. bird
laive
noun. ointment
A word for “ointment” in The Etymologies of the 1930s derived from primitive ᴹ✶laibē under the root ᴹ√LIB (Ety/LIB²). The (archaic?) form laiwe appeared in notes written around 1940 as a cognate to N. glaew (TMME/53).
Conceptual Development: In the Qenya Lexicon of the 1910s Tolkien had ᴱQ. oine “unguent” and ᴱQ. oinalis (oinaliss-) “ointment”, both under the early root ᴱ√OẎO (QL/71). ᴱQ. oine “unguent” also appeared in the contemporaneous Poetic and Mythological Words of Eldarissa (PME/71).
-ite
suffix. (verbal) adjective ending
ialasse
place name. Everlasting Whiteness
mennai
conjunction. until
hún
noun. earth, earth, *ground
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.
ia
adverb. ever
iale
noun. everlasting age
laire
noun. summer
osse
noun. terror
tenna
preposition. until
tyelima
adjective. final
ullume

Another name for Avakúma appearing in The Etymologies from the 1930s as combination of oia “everlasting” and kúma “void” (Ety/OY, EtyAC/OY).
