Alphabet
An alphabet is a standard set of letters—basic written symbols or graphemes—each of which represents a phoneme in a spoken language, either as it exists now or as it was in the past. There are other systems, such as logographies, in which each character represents a word, morpheme, or semantic...

Pitman Shorthand
Pitman shorthand is a system of shorthand for the English language developed by Englishman Sir Isaac Pitman , who first presented it in 1837.
