"Fame-wolf." The father of Hati Hróðvitnisson, the wolf that will swallow the moon, according to Grímnismál.
It seems to be another name for the wolf Fenrir. In Lokasenna, Týr says to Loki that Fenrir may have torn off his right hand, but that Loki has lost his "famed-wolf" (hróðrsvitnir) and that the animal shall remain bound until Ragnarök.
There is no other mention of Fenrir having any offspring.
The Thorpe edition translates the word as "honest fame."
- Grímnismál, 39.
- Lokasenna, 38-39.
