Modern English
Modern English (sometimes New English or NE as opposed to Middle English and Old English) is the form of the English language spoken since the Great Vowel Shift in England, which began in the late 14th century and was completed in roughly 1550.
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:
Artichokes, Bubbly,
Caviar, Dishes
Epicures Favor,
Gourmets Hail;
Ices, Juicy
Kickshaws, Luxurious
Mousses, Nibblesome
Octopus, Pheasant,
Quiches, Sweets,
Treats Utterly
