-yë (4) conj. "and" as a suffix added to the second of a pair, as Menel Cemenyë "Heaven and Earth" (VT47:30, 31, VT49:25). Other "pairs" are mentioned as examples but not actually translated into Quenya by Tolkien: Sun and Moon (*Anar Isilyë), Land and Sea (*Nór Eäryë), fire and water (*nárë nenyë, or *úr nenyë).

anat conj. "but" (VT43:23; possibly an ephemeral form)
and
and
a (2) conj. "and", a variant of ar occurring in Fíriel's Song (that also has ar; a seems to be used before words in f-, but contrast ar formenna "and northwards" in a late text, VT49:26). According to PE17:41, "Old Quenya" could have the conjunction a (as a variant of ar) before n, ñ, m, h, hy, hw (f is not mentioned), PE17:71 adding ty, ny, hr, hl, ñ, l, r, þ, s. See ar #1. It may be that the a or the sentence nornë a lintieryanen "he ran with his speed" (i.e. as quickly as he could) is to be understood as this conjunction, if the literal meaning is "he ran and [did so] with his speed" (PE17:58).
apa
but
apa (3) conj. "but": melinyes apa la hé "I love him but not him" (another) (VT49:15)
apa
conjunction. but
ar
and
ar (1) conj. "and" (AR2, SA, FS, Nam, RGEO:67, CO, LR:47, 56, MC:216, VT43:31, VT44:10, 34; see VT47:31 for etymology, cf. also VT49:25, 40). The older form of the conjunction was az (PE17:41). Ar is often assimilated to al, as before l, s (PE17:41, 71), but "in written Quenya ar was usually written in all cases" (PE17:71). In one case, Tolkien altered the phrase ar larmar "and raiments" to al larmar; the former may then be seen as representing the spelling, whereas the latter represents the pronunciation(PE17:175). More complex schemes of assimilation are suggested to have existed in "Old Quenya", the conjunction varying between ar, a and as depending on the following consonant (PE17:41, 71). An alternative longer form of the conjunction, arë, is said to occur "occasionally in Tolkien's later writings" (VT43:31, cf. VT48:14). In the Etymologies, the word for "and" was first written as ar(a) (VT45:6). In one source, Tolkien notes that Quenya used ar "as preposition beside, next, or as adverb = and" (PE17:145); compare ara.
ar

arato
noble
arato noun "a noble" (PE17:147), in PE17:118 given as aratō and there glossed "lord" (often = "king"). Cf. aráto. The form cited in the latter source, aratō with a long final vowel, is evidently very archaic (compare Enderō under Ender); later the vowel would become short. (PE17:118)
arquen
noble
arquen noun "a noble" (WJ:372), "knight" (PE17:147)
arë

mal conj. "but" (VT43:23)
mal
conjunction. but
nan
but
nan conj. "but" (FS); the Etymologies also gives ná, nán (NDAN), but these words may be confused with forms of the verb "to be", so nan should perhaps be preferred, unless for "but" one uses the wholly distinct word mal. In Tolkien's later Quenya, it may be that he introduced new words for "but" to free up nan for another meaning (perhaps the adverb "back", compare the prefix nan-).
ná
but, on the contrary, on the other hand
ná (2), also nán, conj. "but, on the contrary, on the other hand" (NDAN; the form nan, q.v., is probably to be preferred to avoid confusion with ná "is", *nán "I am").

yo
and
yo conj. "and", "often used between _two _items (of any part of speech) that were by nature or custom clearly associated, like the names of spouses (Manwë yo Varda), or "sword and sheath" (*macil yo vainë*), "bow and arrows" (quinga yo pilindi), or groups like "Elves and Men" (Eldar yo Fírimor but contrast eldain a fírimoin [dative forms] in FS, where Tolkien joins the words with a, seemingly simply a variant of the common conjunction ar). In one source, yo is apparently a preposition "with" (yo hildinyar* = "with my heirs", SD:56).
Ara-, ar- a prefixed form of the stem Ara- "noble" (PM:344). In the masc. names Aracáno "high chieftain", mothername (amilessë, q.v.) of Fingolfin (PM:360, cf. 344), Arafinwë "Finarfin" (MR:230)
