I'm on it! When I get to Mars, I'll learn martian and add a course. Wait, is there wifi on Mars? On the other hand, we may be better off waiting for the ducks to teach us. Of course by then the ducks will already have taken over Mars too. We can never win :(
But Qo'nos, the Klingon home-world, is probably lightyears away. You'll be able to communicate with other Trekkies in Star Trek's language, which is awesome, but it won't help you in the duck uprising.
It's a vowel change that happens with some words when you pluralise them: and - ænder, bog - bøger, man - mænd, and so on. It's mostly a-æ, o-ø, and u-y. You even have remnants of such a vowel change in English: woman - women.
