Looks like Klingon on Duolingo is finally nearing release, planned for Sept 15th. On launch, Klingon joins Esperanto and, also recently released, High Valyrian in the elite conlang learning club for English speakers. (Duolingo also recently released both Japanese and Korean, and conversation bots for several languages, which are all pretty awesome as well.) To those who worked hard to make this course happen: Qapla’! (Now … how about Trigedasleng and Toki Pona?)
Klingon is the constructed language spoken by the fictional extraterrestrial Klingon species in the Star Trek universe. Created by Marc Okrand, the language itself is centered around spacecraft, warfare, and weaponry — but it also reflects the directness and sense of humor of the Klingon culture. For example, the closest word you can use to express “hello” is “nuqneH,” which actually means “What do you want?”. There are also plenty of insults, as it is considered an art form.
The mastery of Klingon is extremely uncommon on Earth. Join the galactic elite and start learning this fascinating language.
