[5, 7] ôttu kosta kvistingar sín ‘had to strive for the maiming of each other’: The copyists appear to have been confused about the (admittedly complex) motifs and syntax. (a) In this edn kosta is preferred, as the reading of the main ms. and perhaps the lectio difficilior. The finite verb ôttu ‘had’ then governs inf. kosta ‘to strive, endeavour’, which in turn governs the gen. kvistingar ‘maiming’. The gen. pron. sín ‘of each other, of themselves’, referring to the two opposing forces, is then the object of kvistingar (cf. Hkr 1893-1901, IV). (b) The majority of mss have the noun kostu, acc. pl. from kostr ‘choice’. This is the reading preferred by Finnur Jónsson (Hkr 1893-1901; Skj B) and it may be correct, giving the sense ‘had the chance for their own maiming (to be maimed)’.
