What Is a Conlang? Constructed Languages Explained

Quick Answer: A conlang (constructed language) is any language deliberately invented by a person or small team rather than evolved naturally over centuries. The most famous examples are Quenya and Sindarin (J.R.R. Tolkien, 1910s onward), Klingon (Marc Okrand, 1984), Dothraki and High Valyrian (David J. Peterson, 2009 onward), and Esperanto (L.L. Zamenhof, 1887). Conlangs fall into three categories: artistic (for fiction), auxiliary (for international communication), and engineered (to test linguistic ideas).

Language is usually something that happens to a culture — it evolves organically over generations, shaped by migration, conquest, trade, and countless individual conversations. A conlang (constructed language) takes the opposite approach: it's a language that someone decides to create, designing its grammar, vocabulary, and sounds deliberately rather than letting them emerge.

The Definition of a Conlang

Conlang is a portmanteau of "constructed language." The term covers an extraordinarily diverse range of projects:

• International auxiliary languages like Esperanto, designed to facilitate communication across national and linguistic borders
• Artistic languages (artlangs) like Tolkien's Quenya and Sindarin, created for aesthetic pleasure and world-building
• Fictional languages for film and TV like Klingon, Dothraki, High Valyrian, and Na'vi
• Logical languages like Lojban, designed to be grammatically unambiguous
• Experimental languages that test hypotheses about how language affects thought

What unites all these is intentionality: a person or team made deliberate decisions about the language's features, rather than inheriting them from historical use.

A Brief History of Conlangs

People have been creating languages for at least 900 years. Hildegard of Bingen (1098-1179) created the Lingua Ignota — a mystic invented language — in 12th-century Germany. Since then, hundreds of constructed languages have been documented.

The modern conlang movement accelerated in the 19th century with international auxiliary languages. Volapük (1879) and Esperanto (1887) were both serious attempts to give the world a common second language. Esperanto succeeded in building a lasting community that still speaks it today.

The 20th century brought artistic conlangs into the mainstream. Tolkien's lifelong work on Elvish, published across novels, essays, and posthumous compilations, demonstrated that a constructed language could have literary depth equal to any natural language.

The 21st century brought professional conlang creation for entertainment. Marc Okrand (Klingon), Paul Frommer (Na'vi), David J. Peterson (Dothraki, High Valyrian), and many others have created languages for films and television that people actually learn and use.

Why Do People Create Languages?

For fiction and world-building: A language gives a fictional culture authenticity that no amount of description alone can provide. When Tolkien's Elves sing in Quenya, the world of Middle-earth feels real.

For communication: Esperanto sought to transcend the political inequalities embedded in using any nation's native language for international communication.

For art: Language itself can be an artistic medium. Conlangers create languages for the same reason poets choose particular words: because the aesthetic properties matter.

For intellectual exploration: Creating a language forces you to confront fundamental questions about how language works. Why do languages have the features they have? What would a language without grammatical gender look like? What if time-reference worked differently?

For community: The conlang community is small but vibrant. Creating or learning a conlang connects you to this community of linguistically curious people.

The Language Creation Society

The Language Creation Society (LCS) is the primary professional and amateur organization for conlang creators. It organized the competition that led to Dothraki being created for Game of Thrones and hosts the Language Creation Conference.

Start Learning

The greatest conlangs are learnable. Tengwar offers structured lessons in three of the most celebrated: Elvish (Quenya and Sindarin), Klingon, and Dothraki. Each language represents a different creative vision and a different challenge for learners.

The world of constructed languages is vast and fascinating. This is just the beginning.

People Also Ask

What's the difference between a conlang and a dialect? A dialect is a regional or social variation of an existing natural language — it evolves organically, has native speakers, and is not "designed." A conlang is built from scratch by an identifiable creator (or small team) for a specific purpose. Klingon has a creator (Marc Okrand) and a release year (1984); American English has neither.

Is Esperanto a conlang or a real language? Both — those categories don't conflict. Esperanto was constructed by L.L. Zamenhof in 1887 as an auxiliary language, but it's now spoken natively by a small number of children (around 1,000–2,000 worldwide) and used by ~2 million people functionally. It's a conlang that has earned natural-language status.

How long does it take to construct a conlang? Tolkien worked on Quenya for over 60 years (1910s to his death in 1973). Klingon was created in 6 weeks for Star Trek III, then expanded for decades. Dothraki took David J. Peterson about 4 months of intense work on top of George R.R. Martin's existing fragments. The variance is enormous — a "good" conlang takes a year minimum; a "deep" conlang takes a lifetime.

Can a conlang have native speakers? Yes. Esperanto has the most native speakers of any conlang (~1,000+). A handful of children worldwide have been raised speaking Klingon as a first or second language (the most documented case is d'Armond Speers, who raised his son bilingually in Klingon and English for the first three years of life). For Quenya/Sindarin/Dothraki, no documented native speakers exist.

Are conlangs accepted in academic linguistics? Yes — increasingly so. The Language Creation Society (LCS), founded in 2007, runs an annual conference (LCC) attended by working academics. MIT and other universities have taught courses on conlang design. The field is no longer fringe.

Which conlang is easiest to learn? Esperanto is engineered to be the easiest — regular grammar, no irregular verbs, transparent vocabulary roots. Among fictional/artistic conlangs, Dothraki is the most accessible due to its Spanish-influenced phonology and regular SOV structure. Quenya is hardest among the famous ones due to its 10 noun cases.
