mor noun "darkness" (Letters:308; probably just an Elvish "element" rather than a complete word; Namárië has mornië for "darkness")
morë adj. "black" (MOR), "dark, darkness" (Letters:282). In compounds the stem-form mori- (q.v.) appears, since the primitive form was ¤mori.
mornaadjective. black, dark, black of hair, *[ᴹQ.] sombre, *gloomy
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".
morqua adj. "black" (LT1:261; rather morna in LotR-style Quenya)
máraadjective. good, proper, *[ᴹQ.] useful, *fit, *good (of things), *[ᴱQ.] excellent, *mighty, *power, *doughty
Amarië fem. name; perhaps derived from mára "good" with prefixing of the stem-vowel and the feminine ending -ië (Silm)
ala- (3), also al-, a prefix expressing "good" or "well" (PE17:146), as in alaquenta (q.v.) Whether Tolkien imagined this ending to coexist with the negative prefix of the same form (#2 above) is unclear and perhaps dubious.
lúmë (2) noun "darkness" (one wonders if Tolkien confused lúmë "time, hour" and lómë "night") (Markirya)
