ᚱᚢᚾᛟ

From Proto-Germanic *rūnǭ, accusative singular of *rūnō.

• IPA^(key): /ˈruː.noː/

ᚱᚢᚾᛟ (runo /rūnō/) f (accusative plural ᚱᚢᚾᛟᛉ)

1. secret, mystery
2. rune, inscription, message
   • 4th century, inscription on the Einang stone:

     [ᛖᚲ ...]ᛞᚨᚷᚨᛋᛏᛁᛉ ᚱᚢᚾᛟ ᚠᚨᛁᚺᛁᛞᛟ

     [ek ...]dagastiʀ runo faihido

     [I, ...]dagastiz, painted the rune

This word is never attested in the nominative singular. However, by looking at other ō-stem nouns such as ᛚᚨᚦᚢ (laþu), and at the Old Norse descendant, we can presume that it should have been *ᚱᚢᚾᚢ (*runu /⁠rūnu⁠/).
