Detail: The meaning Fenrir is disputed on is thought to be the Old Norse “fen-dweller”. Another idea is the short form of Fenrisúlfr. Which means “Fenris-wolf”, derived from the name Fenris combined with Old Norse úlfr “wolf.” The etymology of the name Fenris is uncertain; it is thought that it is derived from Old Norse fen “moor, marsh, swamp” and Old Norse hris “brushwood, shrub.”
In Norse mythology, Fenrir is a monstrous wolf and is foretold to kill the god Odin during the events of Ragnarök (the end of the world).
J. K. Rowling also uses the name for one of her werewolf characters, Fenrir Greyback, in the popular Harry Potter series.
