How well do you know the 18 languages of this year's IOL? Match sentence to language!

So, following up on yesterday's posts about the 18 languages of this years International Linguistics Olympiad: how well do you know them? Here is a phrase in all of the languages, can you guys match the pairs (without googling)? I've also snuck in one extra language, 2 bonus point if you can label it. The correct answer is found at the bottom, in tiny light-yellow print (copy-paste to elsewhere to read). Happy pairing, let us know how you did in the comments!
