Gregg shorthand is a system of writing that uses symbols to represent sounds, making it faster than traditional writing. Developed by John Robert Gregg in the late 19th century, it is designed for speed and efficiency, allowing users to take notes quickly during lectures or meetings. The system is based on phonetics, meaning it focuses on how words sound rather than how they are spelled. Gregg shorthand is often taught in business and secretarial courses, and it has been widely used by journalists and professionals who need to record information rapidly.
