Development in Anglo-Saxon runes
The Anglo-Saxon futhorc split the Elder Futhark a rune into three independent runes due to the development of the vowel system in Anglo-Frisian. These three runes are ōs ᚩ (transliterated o), ac "oak" ᚪ (transliterated a), and æsc ᚫ "ash" (transliterated æ).
Development in Younger Futhark
The Younger Futhark corresponding to the Elder Futhark ansuz rune is ᚬ, called óss. It is transliterated as ą. This represented the phoneme /ɑ̃/, and sometimes /æ/ (also written ᛅ) and /o/ (also written ᚢ). The variant grapheme ᚯ became independent as representing the phoneme /ø/ during the 11th to 14th centuries.
Rune poems
