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:

The novel forms are "aitch", a regular development of Medieval Latin "acca"; "jay", a new letter presumably vocalized like neighboring "kay" to avoid confusion with established "gee" (the other name, "jy", was taken from French); "vee", a new letter named by analogy with the majority; "double-u", a new letter, self-explanatory (the name of Latin V was "ū"); "wye", of obscure origin but with an antecedent in Old French "wi"; "zee", an American leveling of "zed" by analogy with the majority; and "izzard", from the Romance phrase "i zed" or "i zeto" "and Z" said when reciting the alphabet.
