Shorthand is an abbreviated and/or symbolic writing method that increases speed or brevity of writing as compared to a normal method of writing a language. The process of writing in shorthand is called stenography, from the Greek stenos (narrow) and graphē (writing). It has also been called brachygraphy, from Greek brachys (short) and tachygraphy, from Greek tachys (swift, speedy), depending on whether compression or speed of writing is the goal. Many forms of shorthand exist. A typical shorthand system provides symbols or abbreviations for words and common phrases, which allow someone well trained in the system to write as quickly as people speak.
Shorthand was used more widely in the past, before the invention of recording and dictation machines. Until recently, shorthand was considered an essential part of secretarial training as well as being useful for journalists. Although the primary use of shorthand has been to record oral dictation or discourse, some systems are used for compact expression. For example, health-care professionals may use shorthand notes in medical charts and correspondence. Shorthand is also common in the food service industry, allowing wait staff to write down detailed orders without delay.
