[4] vindþvari (m.) ‘wind-borer’: Not attested elsewhere as a cpd. Most likely the sense of this term is ‘one that pierces the air with strokes’ (cf. Meissner 8). Falk (1914b, 63) suggests that the heiti means either ‘oblique-borer’ (from the adj. vindr ‘oblique, warped’) or ‘Wendish borer’, i.e. a Wendish sword (from Vindr, Vindir ‘Wends’). Cf. also ormþvari ‘serpent-borer’ (st. 2/4, see Note there).
