Ægir is a jötunn (giant) who personifies the sea in Norse mythology and is uniquely portrayed as a hospitable host to the Æsir gods.
His name is linguistically linked to Old Norse "ágr," meaning "ocean" or "sea," and he frequently appears in kennings such as "Ægir’s ale" (stormy waves) or "Ægir’s cup" (the sea itself). Students should note that while Ægir is a giant, he occupies a liminal
space—feared for his destructive power yet respected for his generosity. His dual role reflects the Norse view of nature as both nurturing and perilous. Ægir’s wife is Rán, and
together they embody the sea’s contrasting aspects: Ægir as the surface and feasting; Rán as the depths and drowning. His appearances in the Prose Edda (especially Skáldskaparmál) and Lokasenna make him a rich
figure for analyzing personification and metaphor in eddic and skaldic poetry.
