There are more words but they are from Tolkien's earlier conceptional periods. Tolkien likely changed these words as he evolved the aesthetics and completeness of the languages. You may even find languages that Tolkien later rejected. Do not mix words from different time periods unless you are familiar with the phonetic developments.

A noun in The Etymologies of the 1930s glossed “pool” derived from the root ᴹ√LIN of the same meaning (Ety/LIN¹).
Conceptual Development: A similar word ᴹQ. linde “pool” appears in the Declension of Nouns from the early 1930s (PE21/10), but this word is probably best avoided, as it clashes with Q. lindë “singing, song” (PE17/80).

Below: Tolkien's Late Period (1950–1973). These are from Tolkien's late conceptual period — his most settled forms of the languages. Prefer these over the earlier ones above when composing new text.
Demonstrative, Relative, and Correlative Stems (DRC) from 1948 had a set of neuter/abstract pronominal forms for the “other [thing]”. A rejected draft of the pronominal section first had {arya} “something else” (PE23/103 note #40). In the revised page Tolkien first gave apa, apana “another matter; quite a different matter”, revised to assa, astana and finally aiana, aina, with the gloss revised to “anything else; some other matter; a different matter” (PE23/104 and note #54). In this document, the neuter pronouns referred only to abstract facts; for concrete objects the personal pronoun ᴹQ. aiane was used.
DRC also had a set of adjective forms that underwent similar changes (PE23/105 and note #68). Tolkien first had apa, apana “other, quite different”. Tolkien revised this into two separate adjective forms warya “other, different” and warya, warimma “any other”. The first adjective was revised to asta, aia, then asta was deleted. The second adjective became aiana and its gloss was changed to “alien, strange, any other”, with a hard-to-read variant astana that was deleted. Later in the same document Tolkien had {arima or estima “of other kind” (PE23/106 note #80) >> warya, warima “of other sort” >>} aiana (aia) “of another sort, other” and aianima “of other sort” PE23/107 and note #89).
The full development seems to be {arya >> apa(na) >> warya >> assa, asta(na) >>} aia(na) used as both adjectives and (neuter/abstact) pronouns, with {arima/estima >> warimma >>} ᴹQ. aianima meaning “of other sort” (see that entry for details).
See the entry ᴹQ. aia(na) for references to the adjective forms from DRC. See the entry Q. hyana for a discussion of adjective forms in other conceptual periods with similar meaning.
