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.
ar-
prefix. outside, beside
are
noun. day
aran
noun. king
ara
preposition. outside, beside
all(an)ar
adverb. *on no day
ilq(an)ar
adverb. all the day
A correlative combination in Demonstrative, Relative, and Correlative Stems (DRC) from 1948 (PE23/110), a combination of ᴹQ. ilqa “all the” and ᴹQ. -ar(yas) “day”.
Neo-Quenya: For purposes of Neo-Quenya I would update this to ᴺQ. ilquaurë “all the day”, since the later word for “day” is aurë.
ekarnetu ar mekarnenthu
*he made the pair and they made the other pair
atar
noun. father
alaryas
adverb. *on no day
earen
noun. sea
ecarnetin ar mecarnensin
*he made them and they made the other them
e·karne ar the·kar...
*he did and he (other) did
e·venya ther ar la valya venyate·ko
he heals these others but not can heal him(self)
i·nér né raiqa ar sí aphastat
the man was angry but now is in good humor (lit. it pleases him)
lálar
adverb. *on no day
se·linner ar the·línaner
they sang but the others were silent
aia-
prefix. other, different (of larger numbers)
A prefix for “other, different” appearing in Demonstrative, Relative, and Correlative Stems (DRC) from 1948 (PE23/99). Tolkien considered several prior forms on the page where it appeared: {asta} >> {aia < asya} >> aia < ᴹ√AYA (PE23/99 note #27). Earlier drafts had {ar} (PE23/101 note #36) >> {ap-, apana-} >> {war- < gwar-} (PE23/102 note #36). Forms appearing in the rest of the document mostly showed {war(a)-} >> ai(a)-.
Neo-Quenya: For purposes of Neo-Quenya, I would use later hya- as the basis for “other” words, as with (pron.) hya “other thing” and (adj.) hyana “other” (VT49/14).
ette
adverb/adjective. outside
ava-
prefix. without
vea
noun. sea
yo
conjunction. and
aire
noun. sea
airen
noun. sea
ala
noun. day
au-
prefix. without
ye

yu
conjunction. and
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.
The correlative combination ᴹQ. {(a)láqanar >>} allanar or allar appeared in Demonstrative, Relative, and Correlative Stems (DRC) from 1948 along with variants lálar and {láqanaryas >>} alaryas (PE23/109 and note #114), basically combinations of ᴹQ. alla “none” and ᴹQ. -ar(yas) “days”.
Neo-Quenya: For purposes of Neo-Quenya I would update this to ᴺQ. alaurë “on no day” using later aurë for “day”.
