About Ithkuil
Ithkuil.net presents A Grammar of New Ithkuil, a reference for the constructed human-usable language. The language uses a matrix of grammatical concepts intended to express deeper levels of human cognition more overtly, logically and precisely than natural languages. This version revises the earlier Ithkuil with suggestions from fans and new ideas from its author, and its structure is described as more systematic and regularized than its predecessor's, potentially making it easier to study and learn.
