Chinese or Russian

Nadsat.

German.

Body language. I know that's a sort of a crappy answer, but I love communicating without words. You can transcend language and let people know things that you might not be able to with just words.

English.

French is a beautiful language <3 sadly not so much when I speak it...

For me, it's Irish Gaelic, closely followed by Scottish Gaelic. Very nice sound to the words, with a great accent.

I really like Danish and Korean.

I think that Korean sounds just wonderful. Something about the prosodic pattern of it makes me happy.

Additionally, I really love the Busan dialect, but I wouldn't say that it's beautiful. Just, there are remnants of an old tonal system in it that make it really interesting to listen to, and I find it fascinating from a linguistic standpoint considering how it differs from the standard. I would really love to learn that dialect just so I could study its inner workings, ahaha.

anything but german...

hungarian is the best

Tolkien's Elvish

German or Hungarian x

Deutsch

n3t sp3ak.
_{I want to go with French or Russian in all seriousness.}

I'd have to say 'Japanese'

Italiano und Deutsch.

Italian and Japanese!!!

I love how French sounds, but I hate the way it's written. I also love how Arabic is written but don't really like how it sounds...
German can be pretty sweet, and Russian, and Japanese. My father says he don't think it's a coincidence that ever language I like have been involved in some huge fucking war
