The world’s most spoken constructed languages

A natural language is a communication system that spontaneously arises among individuals. Natural languages, then, have not been designed by anyone. They appear naturally, as their name suggests. So what is a constructed language?
Well, constructed languages are created by humans with a specific objective in mind. Depending on these objectives, artificial languages can be categorized into two main groups: controlled languages and artistic languages.

Controlled languages

Languages designed to facilitate human communication. They are based on logic and designed to complement existing natural languages.
Here are the most common controlled languages.

#1 Esperanto

The most spoken constructed language in the world, present in at least 120 countries.
Esperanto was created in 1877 by Doctor L. L. Zamenhof, who wanted to inculcate an easy and neutral language. It has a completely phonetic writing and no grammatical genre. Zamenhof also took out verbal conjugations and irregular tenses. In addition to that, the vast majority of its terms are created by combining affixes, which makes vocabulary learning easier.
Are you up for it?  😉

#2 Lojban

This language was created in 1988 by an association called Logical Language Group. Lojban is a very flexible and neutral language, and its vocabulary is based on the terminology of the world’s most spoken natural languages: Hindi, English, Mandarin, Russian, Spanish and Arabic. Today, the number of lojban speakers is not clear. Nevertheless, it is estimated that this constructed language is present in more than 20 countries.

#3 Interlingua

Our last controlled language is the the one that is the least used (between 100 and 1500 speakers approximately), but it has followers in several territories, especially in the Nordic countries. This constructed language is able to evolve, and it adapts to the characteristics of today’s society, adding and replacing vocabulary.

Artistic languages

Artistic languages are those specifically designed for artistic productions, especially audiovisual and literary ones. When the production is particularly popular, a whole community of speakers emerges around them.

#1 Klingon

Created by Marc Okrand for Star Trek, the goal of Klingon was to get as far away from the human language as possible. Despite having an extremely difficult pronunciation and a very limited vocabulary (mainly galactic terminology), this language has a rather large fan community and thousands of students around the world.
There’s even a Google Klingon!
Here is its alphabet:

#2 Sindarin

Sindarin is an Elvish language that appears in the literary saga The Lord of the Rings. British philologist J. R. R. Tolkien, author of the books, was so committed to his work that he personally designed all the languages spoken by his various characters. Sindarin is not the only dialect spoken by the Elves. It is, however, the most spoken Elvish language in Middle-earth. This language has an analytic grammar structure and many irregular verbs, and it’s phonetically similar to Welsh. The popularity of the books and, later on, the films, made Sindarin very popular among fans.

#3 Na’vi 

Na’ vi was specifically created for Avatar, a motion picture by James Cameron. Its author, Paul Frommer, allows fans of the saga to suggest terminology in order to complete the language. Today, it has 2260 words.

#4 Simlish

Our last artistic language was designed in 1996 by a video game company named Maxis. The speaking pattern got truly famous when it became the official language of The Sims, a social simulation game. Based on symbols and inspired by Ukrainian and French, the Simlish language is a mystery today. Many fans try to translate it, but Maxis prefers to keep its vocabulary a secret.

Are these languages the future? Let’s not forget that the first emoji translator already exists!
At Eazylang, we still don’t have this kind of translators. Do you think we should? Write it in the comment section!

    What about the mangled language, “twin speak”, in the movie “Nell” with Jodie Foster? As far as I remember, there are some examples of the language that Nell and her twin invented.

    Modern Hebrew is another (re)constructed language, like Esperanto undergoing creolization processes right now. Ditto Latin of course.
    (No. Neither was ever spoken anywhere near like today at any point in time and place in history.)
