GrÃÂðr (Old Norse: ) often anglicized as GrÃÂd, is a jötunn in Norse mythology. She is the mother of VÃÂðarr the silent and the consort of Odin. Saturn's moon Gridr was named after her.
The poetic Old Norse name GrÃÂðr has been translated as "vehemence, violence, or impetuosity". Its etymology is unclear.
In Skáldskaparmál (The Language of Poetry), GrÃÂðr is portrayed as equipping the thunder god Thor with her belt of strength, her iron glove, and her staff GrÃÂðarvöl (GrÃÂðr's-staff) on Thor's journey to the abode of Geirröðr.
GrÃÂðr is also mentioned in a list of troll-wives ("I shall list the names of troll-wives. Grid and Gnissa, Gryla...").
GrÃÂðarvöl (GrÃÂðr's staff) is also mentioned in the poem ÃÂórsdrápa by the late-10th-century skald EilÃÂfr Goðrúnarson.
GrÃÂðr appears in 10th-century kennings for 'wolf' (the steed of troll-wife) and for 'axe' (that which is dangerous to the life-protector, i.e. shield or helmet).
Saxo Grammaticus refers to her as Grytha, the wife of the legendary king Dan I of Denmark, "a lady whom the Teutons accorded the highest honour". A witch of the same name appears in Illuga saga GrÃÂðarfóstra.
Her role as the donor of information and necessary items to the hero has been analyzed by folklorists as a commonplace of folk narrative.
