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:
History of English
The Old English of the Anglo-Saxon era developed into Middle English, which was spoken from the Norman Conquest era to the late 15th century. A significant influence on the shaping of Middle English came from contact with the North Germanic languages spoken by the Scandinavians who conquered and colonized parts of Britain during the 8th and 9th centuries; this contact led to much lexical borrowing and grammatical simplification. Another important influence came from the conquering Normans, who spoke a Romance langue d'oïl called Old Norman, which in Britain developed into Anglo-Norman. Many Norman and French loanwords entered the language in this period, especially in vocabulary related to the church, the court system and the government. The system of orthography that was established during the Middle English period is largely still in use today – later changes in pronunciation, however, combined with the adoption of various foreign spellings, mean that the spelling of modern English words appears highly irregular.
