[6] vægir (m.) ‘wavy one’: The word does not otherwise occur as a sea-heiti. According to AEW: vægir 1, it is derived from the weak verb vægja ‘flow, suppurate’, or possibly from vágr m. ‘sea’ (so ÍO: vægir). Vægir ‘wavy one’ is also listed among the sword-heiti (see Note to Þul Sverða 4/1), but it is not clear whether this is a different word.
