As defined by the Cleasby & Vigfusson Old Norse to English dictionary:
- fjöru-maðkr (fjǫru-maðkr)
- m. a kind of worm used for bait.
Orthography: The Cleasby & Vigfusson book used letter ö to represent the original Old Norse vowel ǫ. Therefore, fjöru-maðkr may be more accurately written as fjǫru-maðkr.
