Klingon is the language spoken by Klingons, alien characters in the Star Trek films and TV series. In the 1984 film, Star Trek III: The Search for Spock, the director, Leonard Nimoy, and the writer-producer, Harve Bennett, wanted the Klingons to speak a real-sounding language rather than gibberish, so they commissioned the linguist Marc Okrand to create Klingon.
Okrand based the language partly on Klingon phrases made up by James Doohan (Scotty) for the 1979 film Star Trek: The Motion Picture, and developed a grammar and more extensive vocabulary. Aspects of Klingon language and culture were further developed for the 1987 series, Star Trek: The Next Generation and later series.
To make Klingon sound alien consonants and combinations of consonants, particularly retroflex, velar and uvular ones, uncommon in natural languages are used, such as /q͡χ/.
There is a Klingon dictionary and a number of Klingon courses, and Klingon versions of two Shakespeare plays: Hamlet and Much Ado About Nothing (paghmo' tIn mIS), and also of Gilgamesh (ghIlghameS) and the Tao Te Ching (pIn'a' qan paQDI'norgh). A journal entitled HolQeD (Klingon for linguistics), which conains articles on Klingon linguistics, language and culture, is published by the Klingon Language Institute (KLI). The KLI also publishes jatmey ("scattered tongues"), a magazine featuring poetry and fiction in and about Klingon, as well as runing an annual conference or qep'a ("great meeting").
There are a small number of people able to converse in Klingon, and maybe several hundred others who have some knowledge of the language.
The Astra Image Corporation designed letters to represent Klingon writing for Star Trek: The Motion Picture and based them on symbols created by Matt Jefferies which appear on the Klingon battlecruiser in the film, and also on the Tibetan script. Random Klingon letters are used in the Star Trek films and TV series for effect, and Klingon enthusiasts have devised a way of writing Klingon with them, though Klingon is generally written with the Latin alphabet.

The Kronos Chronicle is a new project of the Klingon Language Institute, intended for Klingon speakers. Here you can read interesting opinons and articles, but only if you can understand Klingon. Each month we will have a new issue for you to read and practice your skill.
