[8] virfill (m.): An obscure word. According to ÍO: virfill 1, the original meaning could have been ‘flexible, supple one’, and the common noun virfill also means ‘rod’ and ‘phallus’ (AEW: Virfill). As a horse-heiti the word appears only in the present stanza, but Virfill is also the name of a sea-king (Þul Sækonunga 5/1).
