https://en.wikipedia.org/wiki/Ithkuil

> Ithkuil is an experimental constructed language created by John Quijada. It is designed to express more profound levels of human cognition briefly yet overtly and clearly, particularly about human categorization. It is a cross between an a priori philosophical and a logical language. It tries to minimize the vagueness and semantic ambiguity in natural human languages. Ithkuil is notable for its grammatical complexity and extensive phoneme inventory, the latter being simplified in an upcoming redesign.

> Meaningful phrases or sentences can usually be expressed in Ithkuil with fewer linguistic units than 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."
