[2] óðu brimslóðir ‘they advanced on the surf-tracks [SEA]’: There is no overt subject here, and brimslóðir ‘surf-tracks’ is f. pl. acc. (of place) with the verb vaða ‘advance’ (lit. ‘wade’; óðu is 3rd pers. pl. pret. indic.). Finnur Jónsson (Skj B) assumes that the missing subject was contained in a following, now-lost line, which is entirely possible and finds support in the fact that vaða is often construed with a term for ‘ship(s)’ as the subject. However, as Kock (NN §1094) points out, 3rd pers. pl. subjects are frequently left out in poetry (see also NS §13 Anm. 2). Faulkes (SnE 1998, II, 418) entertains both possibilities.
