völna ‘shrivel, wither’: This is a hap. leg. It is most likely cognate with OE wealwian ‘dry up, shrivel, wither, decay’ (ModE dial. wallow) and ModNorw. valen ‘numb from cold’ (cf. the parallels ON fǫlna ‘grow pale, shrivel, decay’ and OE fealwian ‘become fallow, fade, wither’). See NN §2868 and AEW: vǫlna.
