[3] hjalm-Njǫrðungum (dat. pl.) ‘helmet-Nirðir’: Pl. Njǫrðungar, derived from the name of the god Njǫrðr, is used in skaldic poetry (only as the second element of cpd nouns) as a base-word in kennings for men. According to Snorri Sturluson, Njǫrðr controls wind and fire (SnE 1982, 23), and Einarr may have used his name in this hap. leg. kenning to emphasize the imagery of smoke and storm.
