Who gave birth to Sleipnir?

The story behind the answer

Loki is the correct answer because, in the Prose Edda, he shape-shifts into a mare to lure away Svaðilfari, the stallion helping a giant build Asgard’s walls. Loki returns pregnant and gives birth to Sleipnir, an extraordinary eight‑legged horse, whom he later gifts to Odin.

Sleipnir’s eight legs symbolize unmatched speed and the ability to travel between realms, fitting Odin’s role as a wanderer and seeker of wisdom. This story also highlights Loki’s trickster nature and fluid shape-shifting, including across genders. Memory tip: “Loki the mare made Odin’s mare-velous mount”—Loki became a mare and produced the most marvelous steed in Norse myth.
