Q: Context : In various poems from the Poetic Edda (stanza 2 of Lokasenna, stanza 41 of Hyndluljo, and stanza 26 of Fjolsvinnsmal), and sections of the Prose Edda (chapter 32 of Gylfaginning, stanza 8 of Haustlong, and stanza 1 of orsdrapa) Loki is alternately referred to as Loptr, which is generally considered derived from Old Norse lopt meaning ''air'', and therefore points to an association with the air.
