[6] þrǫmmungr (m.) ‘lumbering one’: The name is derived from the weak verb þramma ‘lumber along, walk heavily’ (cf. Falk 1925a, 245: ungestüm dringen ‘press on impetuously’). The heiti is not found as a poetic term for ‘hawk’, but along with the previous word it is listed in Þul Fiska 3/1: Fjǫrsungr, þrǫmmungr ‘Weever, mailed sculpin’ (see Note there). It seems that both words were transferred to the þula of hawk-heiti by mistake.
