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:
Abecedarius
Invented by Paul West, a British-born American novelist, poet, and essayist, the alphabet poem is a stricter modern variation of the abecedarius. It consists of 13 lines, each consisting of two words, each word starting with a letter which follows the initial letter of the preceding word. West introduced the alphabet poem in his book "Alphabet Poetry", a cycle of 26 poems, the first of which starts with AB and ends with YZ, the second one starting with BC and ending with ZA, and the last one starting with ZA and ending in XY. Due to the constraints, West allows himself few liberties here and there, as can be witnessed in this example:
