Finally, the Klingon Language is at your fingertips! Download boQwI' to your primitive Terran portable computational device and you will be able to search through its word database, analyze Klingon sentences, and brush up on your etiquette for the big QI'lop celebration.

tlhIngan Hol boQwI' / Klingon Language Assistant is a lexicon dictionary, canon search tool, and grammar analyzer for the Klingon language ({tlhIngan Hol}) devised by Marc Okrand for Star Trek's warrior race. It can parse Klingon grammar and serve as an aid in Klingon-to-English translation. You can also view the Klingon Word of the Day on your Today screen by enabling the included "Klingon Word of the Day" widget.

boQwI' is NOT a general-purpose English-to-Klingon translator. You will need to know some Klingon already to make use of it for that purpose. If you're looking for a general-purpose English-to-Klingon translator (or vice versa), your best bet is to time travel to the 23rd century and bring back a Universal Translator.

Excellent resource

Great app to help learn tlhIngan Hol. Provides word breakdown and English to Klingon and Klingon to English translation. Explains noun and verb suffixes and prefixes. A must have for the Klingon language student.

Best app/online resource I’ve seen so far

Taking a duolingo course in Klingon only goes so far, for one thing it only teaches you the (English only?) transliteration of words & some grammar/syntax. No audio, and no dictionary. When I run into words outside of my lessons that I’m not familiar with, such as watching a subtitled ST episode, boQwI’ never fails to provide valuable insight. The search is quite intuitive as well, I can start typing in English or transliterated Klingon and it will bring up multiple possibilities for what I might be looking for. It also lists and defines the homonyms (and as it turns out, Klingon has a bunch of those) and does a good job explaining the appropriate context when applicable. At my current level of learning, and for such a relatively obscure language, this is by far the best tool I’ve seen. And bonus, it occasionally offers YouTube links to pronunciation videos which are hilarious and awesome. Qapla’!
