lúmë (1) noun "time" (LU, PE17:168) or "hour", locative lúmessë (VT43:34), pl. locative lúmissen "at the times" (VT49:47), allative lúmenna "upon the hour", elided lúmenn' in the greeting elen síla lúmenn' omentielvo "a star shines upon the hour of our meeting", because the next word begins with a similar vowel. The complete form lúmenna omentielvo is found in WJ:367 and Letters:425 (footnote). Cf. also the compounds lumenyárë and lúmequenta, q.v.; see also #sillumë.
Quenya
lúmë
noun. darkness
lúmë
time
lúmë
darkness
lúmë (2) noun "darkness" (one wonders if Tolkien confused lúmë "time, hour" and lómë "night") (Markirya)
lúmë
noun. time, period of time, hour
lumenyárë
history, chronological account
lumenyárë noun "history, chronological account" (NAR2 - read *lúmenyárë?) According to VT45:36, the manuscript spelling actually seems to be lumennyáre, but Hostetter and Wynne conclude that this is "probably a slip": The double nn would be difficult to justify.
lúmequenta
history, chronological account
lúmequenta ("q")noun "history, chronological account" (LU)
lúmequentalë
history
lúmequentalë ("q")noun "history" (LU, KWET). According to VT45:29, the accent marking the ú as a long vowel is actually missing in the entry LU in Tolkien's original Etymologies manuscript; yet it is apparently included both in the entry KWET and in the related words lúmequenta and lúmequentalëa; its omission in the entry LU is therefore probably just a slip.
lúmequentalëa
historical
lúmequentalëa ("q")adj. "historical" (LU)
ullumë
not for ever
ullumë adv.? a word occurring in Fíriel's Song, evidently meaning "not for ever". Cf. ú-, lúmë and úlumë.
lúmequentalëa
adjective. historical
lúmequentalea

lú

ailumë

lúmelissen
adverb. sometimes, at times
malumë

-ssë
at
-ssë (1) locative ending (compare the preposition se, sé "at", q.v.); in Lóriendessë, lúmessë, máriessë, yalúmessë (q.v. for reference); pl. -ssen in yassen, lúmissen, mahalmassen, símaryassen, tarmenissen, q.v. Pronouns take the simple ending -ssë, even if the pronoun is plural by its meaning (messë "on us", VT44:12). The part. pl. (-lissë or -lissen) and dual (-tsë) locative endings are known from the Plotz letter only.
ya
which, what
ya (1) relative pronoun "which, what" (attested in VT43:28, 34 and in the Arctic sentence), with locative suffix in Namárië: see #yassë. According to VT47:21, ya is impersonal, "which" rather than "who(m)" (compare the personal form ye). The dative form yan (q.v.) is however used for "to whom" (rather than "to which") in one text, indicating that Tolkien did not always distinguish between personal and impersonal forms. In the phrase lúmessë ya [variant: yá**] firuvammë, "in [the] hour that we shall die", the relative pronoun is not explicitly marked for case and is evidently understood to share the case of the preceding noun (hence not lúmessë yassë**... "in [the] hour in which"...) (VT43:27-28) Presumably, ya has the plural form *yar* (e.g. i nati yar hirnen** "the things that/which I found").
mor
darkness
mor noun "darkness" (Letters:308; probably just an Elvish "element" rather than a complete word; Namárië has mornië for "darkness")
mornië
darkness
mornië noun "darkness" (Nam, RGEO:67), "dark, blackness" (PE17:73). Early "Qenya" also has Mornië "Black Grief", "the black ship that plies between Mandos and Erumáni" (LT1:261). This is probably a compound of mor- "black" and nië "tear".
se
at, in
se (2), also long sé, preposition "at, in" (VT43:30; compare the "locative prefix" se- possibly occurring in an early "Qenya" text, VT27:25)
A noun in the 1960s versions of the Markirya glossed “darkness” (MC/222), perhaps derived from a root √DU as suggested by David Salo in a post to the Elfling mailing list in 2012 (Elfling/362.96).
Neo-Quenya: I’d generally use Q. huinë for “darkness” in Neo-Quenya, but that word is more for total darkness, whereas lúmë might be a less severe form of darkness, a variant of Q. lómë “night, dusk”.
