rune

Etymology

From Old English 'rūn' (secret, mystery, whispered counsel, runic letter), from Proto-Germanic *rūnō (secret, mystery, rune), from Proto-Indo-European *rewH- (to roar, to murmur). The connection between secrecy and writing reflects the fact that literacy was rare in early Germanic societies — the ability to read and inscribe runes was closely associated with magical knowledge. In Old Norse mythology, Odin hung himself from Yggdrasil for nine days to gain knowledge of the runes, emphasising their mystical status. The modern sense of 'rune' as simply a letter in the runic alphabet is a scholarly development; the original meaning was always bound up with mystery and power. Key roots: *rūnō (Proto-Germanic: "secret, mystery").

Rune traces back to Proto-Germanic *rūnō, meaning "secret, mystery". Across languages it shares form or sense with Old Norse rún, German Rune, Gothic rūna and French rune, evidence of a shared etymological family.
