[6] skerkir (m.) ‘noise-maker’: Agent noun from a weak verb *skerkja ‘make noise’ (see Note to Þul Sverða 2/1). It is also the name of a giant (Þul Jǫtna I 4/4). Ms. B has the synonymous word herkir (from hark ‘tumult’; cf. harkr ‘crackling one’, st. 3/4 below), which, like the name Skerkir, is also found among the giant-names (Þul Jǫtna I 2/3). Neither of these heiti is otherwise used in poetry. RE 1665 has herkir (‘Herkier’) but omits skerkir, which could indicate that the latter is an innovation in A.
