About Klingon
Klingon — officially called tlhIngan Hol in the language itself — is the constructed language of the Klingon people from the Star Trek science fiction franchise and holds the remarkable distinction of being the world's most widely spoken constructed language by number of people with some level of proficiency, according to Guinness World Records. Created by linguist Marc Okrand for Paramount Pictures beginning with Star Trek III: The Search for Spock (1984), Klingon was designed with the explicit goal of sounding genuinely alien while remaining physically speakable by human actors. Okrand succeeded so thoroughly that Klingon developed a global community of learners, a dedicated academic organization (the Klingon Language Institute, founded 1992), translations of Shakespeare and the Epic of Gilgamesh, and even an operatic production. It is one of only a handful of constructed languages — alongside Tolkien's Elvish languages, Esperanto, and Na'vi — to have attracted sustained communities of committed learners.
History and Origins
Klingon's linguistic history begins with Star Trek: The Motion Picture (1979), for which actor James Doohan (Scotty) and producer Jon Povill developed a few Klingon words for dialogue. When Paramount decided for Star Trek III (1984) that the Klingon villains should speak a complete language rather than gibberish, they hired Marc Okrand, a linguist with a PhD from the University of California Berkeley who had already worked on the Vulcan language for Star Trek II. Okrand built Klingon to be systematically un-English: Object-Verb-Subject word order (the opposite of English), verb prefixes indicating both subject and object simultaneously, a phonology loaded with sounds rare in natural languages, and a vocabulary drawn from no existing language family. Okrand published The Klingon Dictionary in 1985, which became a bestseller and established Klingon as a living language project rather than a film prop. The Klingon Language Institute, founded in 1992 by d'Armond Speers (who infamously raised his son from birth speaking only Klingon for the first years of his life), publishes the journal HolQeD and runs annual qep'a' (great meeting) gatherings.
Writing System
Klingon has its own native writing system called pIqaD, an angular script designed to look as if it could have been scratched by claws. pIqaD has 26 characters corresponding to the Klingon phoneme inventory and reads left to right. In Star Trek productions, pIqaD appears on screens and signage throughout Klingon environments. However, most Klingon language learning and communication uses a romanized transliteration system developed by Marc Okrand using the standard Latin alphabet with a very specific case convention: uppercase letters represent sounds that differ from their lowercase equivalents (Q is a uvular stop distinct from q, which is a uvular affricate; H is a voiceless velar fricative distinct from h; I is a vowel distinct from i). This case sensitivity means that Klingon romanization is case-critical in ways that most languages are not.
Phonology and Pronunciation
Klingon was designed to sound alien, and Okrand deliberately chose phonemes rare in natural languages. The result is a consonant inventory that challenges speakers of virtually every natural language in different ways. The sounds tlh (a lateral affricate), q (a uvular affricate), Q (a uvular stop), H (a voiceless velar fricative as in Scottish "loch"), and gh (a voiced uvular fricative) are among the most challenging. The famous OVS word order — where Object comes before Verb which comes before Subject, the reverse of English's SVO pattern — means that "The Klingon sees the human" becomes "the human the Klingon sees" in direct word-for-word mapping. Klingon verbs carry prefixes indicating both subject and object, making a single Klingon verb form equivalent to an entire English clause in some cases.
Famous Texts and Cultural Works
The Klingon Dictionary by Marc Okrand (1985, expanded 1992) is the foundational reference for the language and has sold over 300,000 copies. Okrand subsequently published Klingon for the Galactic Traveler (1997), expanding the vocabulary and cultural context. The Klingon Language Institute has published Hamlet (paraphrased as "To be or not to be" as "taH pagh taHbe'" — "to continue or not to continue") and Much Ado About Nothing in Klingon, arguing the Klingon cultural position that "Shakespeare was originally written in Klingon." The Epic of Gilgamesh has been translated into Klingon. In Star Trek: Discovery, linguists were employed to develop new Klingon dialogue, and in the prequel series Strange New Worlds, Klingon continues to evolve as a living language project.
How to Learn Klingon Today
Learning Klingon is a commitment to one of the most unusual language learning experiences available. The Duolingo Klingon course, launched in 2018, has attracted millions of users and provides a structured introduction. The Klingon Language Institute offers courses, correspondence programs, and the annual qep'a' gathering where intensive Klingon practice occurs. The pIqaD script can be learned in a day or two of focused practice. The grammar — particularly the OVS word order and the verb prefix system — requires sustained study and practice. Klingon proficiency is measured informally within the KLI community, and a small number of people worldwide have achieved genuine conversational fluency. For most learners, Klingon is an intellectually engaging hobby that deepens appreciation of Star Trek lore and provides an unusual context for exploring linguistic structure.
Frequently Asked Questions
Is Klingon a real language?
Yes, Klingon is a real constructed language with a complete grammar, a documented vocabulary of several thousand words, and a community of speakers. It was developed by linguist Marc Okrand with the same systematic rigor that professional linguists bring to language description. While it was created for a science fiction franchise rather than evolving naturally, it functions as a complete linguistic system capable of expressing any concept its vocabulary covers.
How many people speak Klingon?
Estimates of truly fluent Klingon speakers range from 20 to 30 people globally, with perhaps several hundred having significant conversational ability. Millions have basic familiarity with individual words and phrases (Qapla'! — Success!), and the Duolingo Klingon course has attracted millions of enrolled learners. Klingon holds the Guinness World Record as the most widely spoken constructed language.
Who created Klingon?
Klingon was created by linguist Marc Okrand, who holds a PhD in linguistics from the University of California Berkeley. He was commissioned by Paramount Pictures to develop the language for Star Trek III: The Search for Spock (1984). Okrand has remained the primary authority on Klingon ever since, publishing dictionaries, novels, and audio courses, and consulting on Star Trek productions that feature the language.
What does Qapla' mean?
Qapla' (the apostrophe represents a glottal stop) means "Success!" in Klingon and is the most widely recognized Klingon word globally. It functions as both a greeting and a farewell among Klingons — specifically as an expression of good wishes equivalent to "Good luck!" or "May you succeed!" It appears in virtually every Star Trek production that features Klingon dialogue and has entered broader popular culture as a recognizable cultural reference.
