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

lúmë (2) noun "darkness" (one wonders if Tolkien confused lúmë "time, hour" and lómë "night") (Markirya)

lú

lú noun "a time, occasion" (LU)
enwina lúmë
the old darkness
The twenty-eighth line of the Markirya poem (MC/222). The first word is enwina “old” followed by the noun lúmë “darkness”, possibly a variant of more common lómë as suggested by Helge Fauskanger (AL/Markirya).
Decomposition: Broken into its constituent elements, this phrase would be:
> enwina lúmë = “✱old darkness”
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".
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”.
