Klingon

The Klingon alphabet (tlhIngan pIqaD) is the creation of an unknown inventor at Paramount. In the Star Trek TV series and movies random letters from the alphabet are used for effect. There is no official mapping of the Klingon letters to the Latin alphabet, but the one shown below is generally used by tlhIngan pIqaD enthusiasts. Most people who speak Klingon prefer to use the Latin alphabet to write it.

There are perhaps 20 or 30 fluent speakers of Klingon, and some 500 or 600 people who have some knowledge of the language.

Used to write

Klingon (tlhIngan Hol), a language created by Dr Marc Okrand, a professional linguist, for use by the alien Klingons in some of the Star Trek movies. To make Klingon sound truly alien, Okrand used combinations of sounds which do not exist in any natural language. It is a complete language, with its own vocabulary, grammar, usage and an enthusiastic community of speakers.
