As defined by the Cleasby & Vigfusson Old Norse to English dictionary:
- at-tönn (at-tǫnn)
- f. [at, n.], a tusk, Fas. i. 366.
Orthography: The Cleasby & Vigfusson book used letter ö to represent the original Old Norse vowel ǫ. Therefore, at-tönn may be more accurately written as at-tǫnn.
Possible runic inscription in Younger Futhark:ᛅᛏ-ᛏᚢᚾᚾ
