Dagaz

The d rune (ᛞ) is called dæg "day" in the Anglo-Saxon rune poem. The corresponding letter of the Gothic alphabet 𐌳 d is called dags. This rune is also part of the Elder Futhark, with a reconstructed Proto-Germanic name *dagaz. Its "butterfly" shape is possibly derived from Lepontic san. The rune may have been an original innovation, or it may have been adapted from the Rhaetic's alphabet's D.
