Shorthand is an abbreviated symbolic writing method that increases speed and brevity of writing as compared to longhand, a more common method of writing a language. The process of writing in shorthand is called stenography, from the Greek stenos (narrow) and graphein (to write). 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 can allow someone well-trained in the system to write as quickly as people speak. Abbreviation methods are alphabet-based and use different abbreviating approaches. Several programs, standalone or integrated in text editors, based on word lists, also include a shorthand function for frequently used phrases. Many journalists use shorthand writing to quickly take notes at press conferences or other similar scenarios.
Shorthand was used more widely in the past, before the invention of recording and dictation machines. Shorthand was considered an essential part of secretarial training and police work, as well as 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, healthcare professionals may use shorthand notes in medical charts and correspondence. Shorthand notes are typically temporary, intended either for immediate use or for later typing, data entry, or (mainly historically) transcription to longhand, although longer term uses do exist, such as encipherment: diaries (like that of the famous Samuel Pepys) are a common example.
The earliest known indication of shorthand systems is from the Parthenon in Ancient Greece, where a mid-4th century BC marble slab was found. This shows a writing system primarily based on vowels, using certain modifications to indicate consonants. Hellenistic tachygraphy is reported from the 2nd century BC onwards, though there are indications that it might be older. The oldest datable reference is a contract from Middle Egypt, stating that Oxyrhynchos gives the "semeiographer" Apollonios for two years to be taught shorthand writing. Hellenistic tachygraphy consisted of word stem signs and word ending signs. Over time, many syllabic signs were developed.
