Wyrd is a concept in Anglo-Saxon culture roughly corresponding to fate or personal destiny. The word is ancestral to Modern English weird, whose meaning has drifted towards an adjectival use with a more general sense of "supernatural" or "uncanny", or simply "unexpected".
The cognate term to wyrd in Old Norse is urðr, with a similar meaning, but also personified as a deity: Urðr (anglicized as Urd), one of the Norns in Norse mythology. The word also appears in the name of the well where the Norns meet, Urðarbrunnr.
