English terms with diacritical marks
The Old English Latin alphabet began to replace the Runic alphabet in the 9th century, due to the influence of Celtic Christian missionaries to the Anglo-Saxon kingdoms. The orthography of Old English – which was entirely handwritten in its own time – was not well standardized, though it did not use all the Latin letters, and included several letters not present in the modern alphabet. When reprinted (on a printing press or computer) in modern times, an overdot is occasionally used with two Latin letters to differentiate sounds for the reader:
English language
Old English was divided into four dialects: the Anglian dialects, Mercian and Northumbrian, and the Saxon dialects, Kentish and West Saxon. Through the educational reforms of King Alfred in the ninth century and the influence of the kingdom of Wessex, the West Saxon dialect became the standard written variety. The epic poem "Beowulf" is written in West Saxon, and the earliest English poem, "Cædmon's Hymn", is written in Northumbrian. Modern English developed mainly from Mercian, but the Scots language developed from Northumbrian. A few short inscriptions from the early period of Old English were written using a runic script. By the sixth century, a Latin alphabet was adopted, written with half-uncial letterforms. It included the runic letters "wynn" and "thorn" , and the modified Latin letters "eth" , and "ash" .
