adjective. good
mára

Amarië
good
ala-
good
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.
mára adj. "useful, fit, good" (of things) (MAG; see MA3; Arct, VT42:34, VT45:30). Nás mara nin "I like it", literally "it is good to me" (VT49:30; read mára for mara?) As the comparative of mára, the unrelated adjective arya "excelling" is used in the sense of "better"; for the superlative *"best", one adds the article: i arya (with genitive to express "the best of…") (PE17:57),
