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
English underwent extensive sound changes during the 15th century, while its spelling conventions remained largely constant. Modern English is often dated from the Great Vowel Shift, which took place mainly during the 15th century. The language was further transformed by the spread of a standardized London-based dialect in government and administration and by the standardizing effect of printing, which also tended to regularize capitalization. As a result, the language acquired self-conscious terms such as "accent" and "dialect". As most early presses come from continental Europe, a few native English letters such as þ and ð die out; for some time "þe" is written as "ye." By the time of William Shakespeare (mid 16th - early 17th century), the language had become clearly recognizable as Modern English. In 1604, the first English dictionary was published, the "Table Alphabeticall".
