Valar morghulis, dear Lingohubbers. 

You’re probably familiar with this term. It might be through HBO's Game of Thrones show, or George R.R.Martin’s A Song of Ice and Fire or just thanks to the huge amount of social media posts and hashtags. The truth is, constructed languages have a huge place in popular culture, but that's not all...

The Game of Thrones wave brought new phrases into everyday conversation, making artificial languages and "Valar morghulis" almost as easily recognized as "Carpe Diem".

But what are these artificial languages? How are they created and how do they influence the times we live in?

That's what we will be discussing in this article.

Natural languages vs. constructed languages

A typical language develops and evolves through time and the use of its speakers. The vocabulary expands, changes with the demands of the physical environment, or even adopts different linguistic influences.

Just like traditional Latin didn’t include words which describe electronic letters and inboxes, a couple of decades ago we didn’t have a word for emojis and following someone was a criminal offense - not an everyday activity on social media platforms.

But unlike natural languages, which develop its phonology, grammar and vocabulary slowly and usually under the influence of a great number of people, constructed languages present a conscious act of creation.  

Constructed languages or conlangs are artificially created languages. In this case, humans create all segments of the language in a shorter period of time, usually with a specific purpose in mind. 

While natural languages have a group of native speakers, in addition to non-natives who adopt the language; constructed languages have no native speakers. Essentially, majority of conlang speakers adopt the language. Of course, there are some exceptions to the rule, which we will discuss shortly. 

In general, the differences between natural and constructed languages is:

Natural LanguagesConstructed Languages
Created by a group of people Created by one person
Develop through time Developed in a short period
Native speakers &
non-native speakers exist
Non-native speakers only\*

So, why would someone decide to create a language, you might ask. And what does it take to create a whole language from scratch?

Artificial languages 101

While there are many ways to classify constructed or artificial languages, we will rely on a twofold classification in this article:

a) the goal of creation and
b) structure of the constructed language

Observing the goal, or answering the question - why someone might want to create a language brings us to the following sections: 

  • Engineered languages - constructing a language with a specific need for linguistic experimentation
  • Auxiliary languages - created to serve as a supporting communication tool.  
  • Artistic languages - created usually to support a work of fiction. In this article, we will look at and analyze the creation and usage of constructed languages that have gathered worldwide recognition.

The structure of constructed languages can depend on a number of elements. The starting point, however, is deciding how much will the creator of the language “borrow” from existing languages. This way, we can differentiate

  • A posteriori languages - a posteriori languages use elements from existing languages and build its linguistic core on established vocabulary, grammar rules and sentence structure. The most prominent example would be Esperanto
  • A priori languages - a priori languages are languages with an original structure and features. If they take vocabulary, pronunciation or grammar inspiration from existing languages - it is in a smaller amount. Many artistic or fictional languages were created a priori - with their own grammar, vocabulary and writing script. Notably: Klingon, Dothraki, Valyrian, and the myriad of languages created by J.R.R. Tolkien.

Conlangs and Controversy

Constructed languages have been quite a controversial topic. The popularity of shows such as Game of Thrones certainly influenced the adoption of phrases (Valar dohaeris) and names (over 500 baby girls have been named Khaleesi in USA in 2018). 

In addition, there is a question if conlangs fall under protection of intellectual property. This creates the legal controversy:

An interesting study by Michael Adelman - “Constructed languages and copyright: A brief history and proposal for divorce” analyses the issue from its legal point).  

Another point is the question of whether or not it is possible to have native speakers of constructed languages. According to the website Ethnologue, the answer is - yes. Esperanto has around 2,000 native speakers. It is the most massive and frequently used conlang in the world.

Esperanto is not the only case, however. Dr. d'Armond Speers, a member of Klingon Language Institute, tried to raise his child as a bilingual, native speaker of Klingon, with no notable success - but not for a lack of effort. 

ISO recognition of constructed languages

In our article on ISO Language Codes, we outlined the ISO standardized codes which are assigned to artificial, or constructed languages. 

However, not all popular artificial languages get this ISO recognition.
The use of language, the growing body of literature (translating books into artificial languages), and the popular online language courses in artificial languages are definitely influencing these decisions.

Language ISO 639 ISO 639-2 ISO 639-3


This auxiliary constructed language was created in the 19th century by L.L.Zamenhof.

Initially, Zamenhof’s idea was to create a language which would be universally used and serve as a second language in a more connected world.

Esperanto represents a linguistic Utopia

Although his idea of a language of international understanding might seem Utopian to some, it remains a fact that Esperanto is rather easy to master. Moreover, there is a lot of speculation if studying Esperanto helps speakers learn and adopt other languages easily later on.

The United Nations recognized it as an international auxiliary language in 1954.

Further recognition came with the Nobel Prize in Literature nomination in 1999. William Auld is the first ever nominee for a body of work written in Esperanto. The history of Esperanto has been a rocky one, especially with prosecution of speakers during World War II.

At the moment, Esperanto has around 2 million speakers. 

Fictional constructed languages

Fictional or artistic conlangs are a specific linguistic category.

In contrast to other constructed languages, fictional conlangs are not created with real-life usage in mind. In fact, artistic conlangs are created to be a part of a fictional narrative. Basically, made up languages make movies, TV series, video games and books more believable.

They are typically created by individuals, conlanging experts, with a particular group of speakers within the narrative. The fictional characters are the actual only natives of such languages - so far. 

Further, we will take a look at some of the most prominent fictional languages. 


Arguably, one of the most popular fictional languages, which has taken a life of its own since its creation is Dothraki.

Dothraki was constructed for the needs of George R.R.Martin’s series of books A Song of Ice and Fire. Consequently, for the needs of the HBO’s Game of Thrones show, Dothraki got a full grammar and an extended vocabulary.

The man charged with this daunting task was the linguist David J. Peterson, who based on Martin’s notes on the language and description of the native speakers - built up the whole language.

The native language of the fictional nomadic nation of Martin’s novels has grown outside of the show - with millions of tutorials available on the web.

Just as with the natural languages, Dothraki is evolving as the number of its speakers is growing.

This effect is motivating even its creator, David Peterson to reconsider the structure of the language and evolve it. Consequently, as he explained, he was inspired by the use of Dothraki in the famous American TV Show The Office. He recognized changes that need to be added to the language and added a so-called Schrutean compound.  

High Valyrian

After the successful creation of Dothraki, David Peterson continued to work on developing the languages for Game of Thrones. More precisely, he worked on the development of High Valyrian, the mythical mother tongue of the protagonist Daenerys Targaryen.

In creation of High Valyrian, Peterson drew inspiration from Latin - especially its usage among the European nobility. Hence, High Valyrian functions as the language of higher education in the fictional Esos and Westeros. Additionally, Peterson developed derivatives of High Valyrian for the needs of the show. These include Astapori and Meereenese varieties of High Valyrian.

Interestingly, although created as a fictional language, High Valyrian found its place in the real world as well. Starting from 2017, and with the great help of Peterson, High Valyrian has been available on the popular language learning platform Duolingo

Arguably one of the most popular artificial fictional languages comes from the Star Trek universe. It was originally created as the native language of the fictional Klingon nation for the Star Trek: Motion Picture back in 1979.

However, Klingon grew into a real language after its creator Marc Okran released the grammar and expanded vocabulary. Marc Okran developed Vulcan, as well, for the same franchise. Later on, he developed the Atlantean language for the Disney picture Atlantis: The Lost Empire.

In the previous decades, Klingon grew into a movement of sorts. Klingon Language Institute (KLI) operates in the USA since 1992. KLI functions as a non-profit that focuses on translation of notable literary works into Klingon.

So far, six translations exist in Klingon: 

  • The Epic of Gilgamesh
  • Hamlet
  • Much Ado about Nothing
  • Tao Te Ching
  • The Art of War
  • The Little Prince

Klingon is available on Duolingo, as well. However, users have noted that, due to the cultural clash between the average current user and the futuristic nation of Klingon - there are some issues in finding the right vocabulary for everyday expression. Klingon course is available on the language learning platform Duolingo .

J..R.R.Tolkien’s languages

The master of conlanging, Tolkien spent around 60 years developing his fictional languages.

Tolkein was a firm believer that a language has to reflect the historical development of the language and the historical development of its speakers and their culture.

That is why he provided a full history of language families present in his literary works.

Most notable languages created by Tolkien include: Elvish (and its derivatives: Quenya and Sindarin, which even have its own ISO codes), followed by several Mannish languages and the Dwarfish language (Khuzdul). 

Other notable mentions

Na’vi - created by Paul Frommer for the needs of James Cammeron’s Avatar movie in 2009. However, since the movie’s release, the vocabulary and grammar have been constructed further into a learnable language.

Syldavian and Bordurian - languages created by Herge, the author of the comic The Adventures of Tintin. Syldavian is based on Central European Languages, like Polish and Hungarian. However, it does include dual script like Serbian, while it is completely Germanic in its grammar and structure.

Gallifreyan from the long-running TV Show Doctor Who and the Heptapod language developed for the movie Arrival, represent forms of visual languages.

The future of conlanging 

Lastly, the increased popularity of fictional constructed languages shows us is the evolution of a language at high speed.

From its inception, adoption, and further development by speakers through use - we can observe how a freshly made language quickly adds slang, pronunciation changes and vocabulary extension.

Creating a new language from scratch might not be for everyone. However, you can provide native speakers with a good translation - with a little help of the right tools.

Lingohub supports translation to Esperanto, because we believe in the power of multilingual content. And who knows - maybe Klingon and High Valyrian are next?
