🔗 Ithkuil is an experimental constructed language. Nobody speaks it fluently

Ithkuil is an experimental constructed language created by John Quijada. It is designed to express deeper levels of human cognition briefly yet overtly and clearly, particularly with regard to human categorization. It is a cross between an a priori philosophical and a logical language. It tries to minimize the vagueness and semantic ambiguity found in natural human languages. Ithkuil is notable for its grammatical complexity and extensive phoneme inventory, the latter being simplified in an upcoming redesign. The name "Ithkuil" is an anglicized form of Iţkuîl, which in the original form roughly means "hypothetical representation of a language". Quijada states he did not create Ithkuil to be auxiliary or used in everyday conversations. He wanted the language to be used for more elaborate and profound fields where more insightful thoughts are expected, such as philosophy, arts, science and politics.

Meaningful phrases or sentences can usually be expressed in Ithkuil with fewer linguistic units than in natural languages. For example, the two-word Ithkuil sentence "Tram-mļöi hhâsmařpţuktôx" can be translated into English as "On the contrary, I think it may turn out that this rugged mountain range trails off at some point". Quijada deems his creation as too complex to have developed naturally, seeing it as an exercise in exploring how languages could function. No person, including Quijada himself, is known to be able to speak Ithkuil fluently. It was featured in the Language Creation Conference's 6th Conlang Relay.

Four versions of the language have been publicized: the initial version in 2004, a simplified version called Ilaksh in 2007, the current version in 2011, and as of 2017, various revisions of a new version of the language, named Ithkuil IV. In 2004—and again in 2009 with Ilaksh—Ithkuil was featured in the Russian-language popular science and IT magazine Computerra. In 2008, David Peterson awarded it the Smiley Award. In 2013, Bartłomiej Kamiński codified the language to be able to quickly parse complicated sentences. Julien Tavernier and anonymous others have followed suit. Since July 2015, Quijada has released several Ithkuil songs in a prog rock style as part of the album Kaduatán, which translates to "Wayfarers". Recently, online communities for the language have developed in English, Russian, Mandarin, and Japanese.
