What Is a Conlang? Constructed Languages Explained

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.
