You can now learn the world's most popular fictional language - tlhIngan.
For non Star Trek fans, that's Klingon - the native tongue of the alien warrior species The Klingons.
Language-learning platform Duolingo has launched a brand new online course that teaches you the language.
Trekkies have been waiting a long time for this, thousands signed up before the launch to take the course.
You'll learn sentence structure, vocabulary and useful phrases through word translation and picture matching.
Klingon isn't Duolingo’s first dabble in fictional language — it already has a course in Game of Throne's High Valyrian.
The Klingon course is currently only available on Duolingo’s website. It will be available on iOS and Android apps at a later date.
