EtymologyGróa is a feminine name derived from Old Norse gróa, meaning "to grow". This root is cognate with Old English grōwan and modern English "grow". The name is used in modern Iceland and historically in Norse-speaking regions.Mythological FigureIn Norse mythology, Gróa is a völva (seeress) and practitioner of seiðr, a form of shamanic magic. She is attested in both the Prose Edda and the Poetic Edda. According to Skáldskaparmál, she was married to Aurvandil the Bold. After Thor killed the jötunn Hrungnir, fragments of Hrungnir's whetstone became lodged in Thor's head. Thor visited Gróa, who began to chant spells to remove them. As she worked, Thor told her about helping Aurvandil cross the Élivágar river, where he carried her husband across in a basket and saved him from frostbite by snapping off his toe. Distracted by this news, Gróa's spell misfired, leaving the stone fragments permanently in Thor's head.In the Poetic Edda poem Grógaldr (The Spell of Gróa), Gróa is a völva who dies and is evoked from her grave by her son, the hero Svafrþóri, to reveal the future. She recites magical charms (galdrar) for his protection, foretelling his meeting with a dangerous giantess and offering guidance.Notable BearersHistorically, the name appears in Old Norse sources, though no well-known modern bearers are recorded beyond literary contexts.Variants and UsageThe expected variant Gro is the modern Norwegian form.
