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.
Shavian alphabet
Shaw had served from 1926 to 1939 on the BBC's Advisory Committee on Spoken English, which included several exponents of phonetic writing. He also knew Henry Sweet, creator of Current Shorthand (and a prototype for the character of Henry Higgins), although Shaw himself used the shorthand system of Isaac Pitman. All of his interest in spelling and alphabet reform was made clear in Shaw's will of June 1950, in which provision was made for (Isaac) James Pitman, with a grant in aid from the Public Trustee, to establish a Shaw Alphabet. Following Shaw's death in November 1950, and after some legal dispute, the Trustee announced a worldwide competition to design such an alphabet, with the aim of producing a system that would be an economical way of writing and of printing the English language.
