Shorthand is an abbreviated symbolic writing method that increases speed and brevity of writing. It is based on the basic alphabet, but uses special symbols, removes unnecessary letters and some vowels, and abbreviates some common words. There are a number of different shorthand systems in use, for example, Teeline, Pitman and Gregg. Shorthand is often used by journalists and court reporters who need to take accurate notes very fast.
