mára

useful, fit, good

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),

nin

to me, for me

nin pron. "to me, for me", dative of ni (FS, Nam). Sí man i yulma nin enquantuva? "Now who will refill the cup for me?" (Nam), nás mara nin *"it is good to me" = "I like it" (VT49:30), ecë nin carë sa* "it-is-open for me to do it" = "I can do it" (VT49:34). See also ninya**.
