For previously unwritten languages Some scripts were invented for spoken languages that did not have adequate writing systems, including the
Hangul,
Cherokee,
Canadian Aboriginal syllabics,
N'Ko,
Fraser,
Goulsse alphabet,
Tangut and
Pollard scripts. The
Armenian alphabet, the
Georgian alphabet, and the
Glagolitic alphabet may fit in this category, and while their origins and creators are known, it is also evident that they are modeled on some level on the
Greek alphabet.
For religious and mystical purposes Many scripts are created for religious or mystical purposes. Missionaries and religious scholars may be motivated to devise new scripts for previously-unwritten languages to facilitate the translation of religious writings, as was the case for several of the scripts mentioned in the previous section. Religious leaders may promulgate new writing systems among their followers for liturgical use and/or the promotion of cultural identity and unity, as with
Sorang Sompeng,
Medefaidrin and the
script invented by the Zomi religious leader
Pau Cin Hau, among many others. Relatedly,
some scripts are created for
mystical or
magical uses, such as communication with purported spiritual entities. Such is the case with
John Dee and
Edward Kelley's
Enochian language and alphabet, the various scripts (including
Celestial,
Malachim,
Theban, and
Transitus Fluvii) documented by
Heinrich Cornelius Agrippa and his teacher
Johannes Trithemius, and possibly the
litterae ignotae devised by
Hildegard of Bingen to write her
lingua ignota. Several of these scripts are described by their creators as having been revealed during or developed in response to
visionary experiences.
In fictional works The best-known constructed scripts dedicated to
fictional languages are
J. R. R. Tolkien's elaborate
Tengwar and
Cirth, but many others exist, such as the
pIqaD script for
Star Trek's
Klingon language, and
D'ni from the
Myst series of video games. Other works stop short of creating entire languages, and instead use constructed scripts as
substitution ciphers or alternate orthographies for existing languages- English-language examples include the script of the Orokin language (referred to by members of the community as "Tennobet", a portmanteau of "
Tenno" and "alphabet") from the video game
Warframe, the unnamed New World script from
Kirby and the Forgotten Land,
Aurebesh from
Star Wars, and the
alien writing appearing in the television series
Futurama.
For technical purposes Several writing systems have been devised for technical purposes by specialists in various fields. One of the most prominent of these is the
International Phonetic Alphabet (IPA), used by linguists to describe the sounds of human language in exhaustive detail. While based on the
Latin alphabet, IPA also contains invented letters, Greek letters, and numerous diacritics. Other scripts, such as John Malone's
Unifon, Sir
James Pitman's
Initial Teaching Alphabet, and
Alexander Melville Bell's
Visible Speech were invented for
pedagogical purposes.
Yerkish, a communication system created for use by non-human primates, involves a system of lexigrams- visual symbols corresponding to various objects and ideas.
Shorthand systems may be considered constructed scripts intended to facilitate speed and ease of writing.
Language reform Some constructed scripts are intended to replace existing writing systems. In the mid-1800s,
the Church of Jesus Christ of Latter-day Saints promoted the
Deseret alphabet as an alternative writing system
better suited to English phonology; roughly a century later, the estate of Irish playwright
George Bernard Shaw commissioned the
Shavian alphabet (later developed into
Quikscript) to serve similar aims. Graphic Designer
Bradbury Thompson's
Alphabet 26 represents a similar project. (see also:
English-language spelling reform). Taking language reform further, various proposed
philosophical or
auxiliary languages- such as
aUI,
Solresol, and the language outlined in
John Wilkins' 1668
An Essay Towards a Real Character, and a Philosophical Language have associated writing systems.
Charles K. Bliss's
Blissymbols represent a proposed international auxiliary language whose primary mode is written rather than spoken.
Other Several constructed scripts serve unique purposes not outlined above.
Ong Kommandam's
Khom Script, in addition to serving a religious role, was used to conceal military communications during the
Holy Man's Rebellion. Around the turn of the 18th century, Frenchman
George Psalmanazar invented a purported 'Formosan' alphabet to further his fraudulent claims of being the first Taiwanese visitor to Europe; the
Coelbren y Beirdd alphabet invented by
Iolo Morganwg is another such example of linguistic forgery.
Braille and most other
tactile alphabets were invented to serve the needs of the visually impaired, or, in the case of
Lewis Carroll's
Nyctography, of sighted people without access to light. ==Encoding==
