Etymology

From Middle English and Old English upper case letter A and split of Middle English and Old English upper case letter Æ. * The Old English letters A and Æ replaced the Anglo-Saxon Futhorc letters ᚪ (a, “āc”) and ᚫ (æ, “æsc”), derived from the Runic letter ᚫ (a, “Ansuz”), in the 7th century.
