adj. part., prop. a legitimate son or daughter, Fms. i. 86; defined, sá er a. er kominn er til alls réttar, N. G. L. ii. 211. Freq. spelt árborinn by suppressing the f (so N. G. L. ii. 50), and used in Norse law of a freeman, v. the quotation above from N. G. L., which clearly shews the identity of the two words, i. 171; algildis vitni tveggja manna árborinna ok skilvænna, ii. 211: the alliterated phrase alnir ok árbornir (the phrase aldir og óbornir may be a corruption from arb.), freeborn and freebred, 310. The passage in Stor. verse 2 is in Lex. Poët. explained by olim ablatus: the poet probably meant to say genuine, pure, in a metaph. sense, of the true poetic beverage, not the adulterated one, mentioned in the Edda 49; the cup from the right cask.
