*Raidō "ride, journey" is the reconstructed Proto-Germanic name of the r- rune of the Elder Futhark ᚱ. The name is attested for the same rune in all three rune poems, Old Norwegian Ræið Icelandic Reið, Anglo-Saxon Rad, as well as for the corresponding letter of the Gothic alphabet 𐍂 r, called raida. The shape of the rune may be directly derived from Latin R.
