As defined by the Cleasby & Vigfusson Old Norse to English dictionary:
- stjörnu-fræðingr (stjǫrnu-fræðingr)
- m. an astronomer.
Orthography: The Cleasby & Vigfusson book used letter ö to represent the original Old Norse vowel ǫ. Therefore, stjörnu-fræðingr may be more accurately written as stjǫrnu-fræðingr.
