[2] Brúnn: Not attested elsewhere as a name for Óðinn. It may be the same as the adj. brúnn ‘brown’ and hence a horse-name transferred to the god (Falk 1924, 5, 40). Cf. Brúnn, the name of a black horse (CVC: brúnn), OE Brūn (and also cf. Vakr, l. 5). Alternatively, Brúnn may be a variant of Brúni (st. 6/4 above) or it could have been derived from the noun brún f. ‘eyebrow’.
