 Stephan Grundy states that the words "Sága" and "Sökkvabekkr" may be by-forms of "Frigg" and "Fensalir", respectively, used for the purpose of composing alliterative verse.Britt-Mari Näsström theorizes that "Frigg's role as a fertility goddess is revealed in the name of her abode, Fensalir [...]", that Frigg is the same as Sága, and that both the names "Fensalir" and "Sökkvabekkr" "imply a goddes ["sic"] living in the water and recall the fertility goddess Nerthus".Näsström adds that "Sökkvabekkr, the subterranean water, alludes to the well of Urd, hidden under the roots of Yggdrasil and the chthonic function, which is manifest in Freyja's character."
