Þ*undr: The reading (normalised) þrundr found in both mss of this þula cannot be interpreted and must have been caused by scribal corruption. The correct form is probably Þundr (so the LaufE mss), one of the most frequently attested Óðinn-names (Falk 1924, 31). That name is mentioned in Grí 46/5 (NK 66: Þundr oc Uðr ‘Þundr and Uðr’) and given again in Grí 54/3, and it would have been conspicuously absent from the present list unless þrundr were a corrupt form of Þundr. The origin of Þundr is unclear. According to Falk (loc. cit.), it is related to the Old English verb þindan ‘swell’ and possibly characterises Óðinn as a god of the stormy sea (cf. Ólgr, st. 6/7). Alternatively, it could be derived from *þuniða-, cf. OE ðunian ‘crash, make noise’ (see ÍO: þundur 1), but cf. also ModIcel. þundur ‘bow’, hence perhaps ‘strained’ (so Olsen 1934, 94-5).
