It is derived from the reconstructed Proto-Germanic (or Common Germanic) word for 'man', *mannaz.
It took up the shape of the algiz rune ᛉ, replacing Elder Futhark ᛗ.
As its sound value and form in the Elder Futhark indicate, it is derived from the letter for /m/, 𐌌, in the Old Italic alphabets, ultimately from the Greek letter mu (uppercase Μ, lowercase μ).
Icelandic: ᛉ Maðr er manns gaman ok moldar auki ok skipa skreytir.
Old English (Anglo-Saxon): ᛗ Man bẏþ on mẏrgþe his magan leof: sceal þeah anra gehƿẏlc oðrum sƿican, forðum drẏhten ƿẏle dome sine þæt earme flæsc eorþan betæcan.
