A constructed script (also artificial script, neography, and conscript for short) is a new writing system specifically created by an individual or group, rather than having evolved as part of a language or culture like a natural script. Some are designed for use with constructed languages, although several of them are used in linguistic experimentation or for other more practical ends in existing languages.
The most prominent of constructed scripts may be the International Phonetic Alphabet and the Korean Hangul script. Some, such as the Shavian alphabet, Quikscript, Alphabet 26, and the Deseret alphabet, were devised as English spelling reforms. Others, including Alexander Melville Bell's Visible Speech and John Malone's Unifon were developed for pedagogical use. Blissymbols were developed as a written international auxiliary language. Shorthand systems may be considered conscripts. On the other hand, specific-purpose writing systems such as Braille and Morse are codes, not conscripts.
The Voynich Manuscript appears to be written in a constructed script (although superficially or to the casual observer it looks like an ordinary manuscript hand of the period).
