Japanese, i know english and spanish with those i can manage around most of the world pretty easly but i like anime and i would like to travel to japan sometime

French, definitely, I've always wanted to get French as my fourth language.

Mandarin, I've wanted to learn that for as long as I can remember...and throw in Cantonese while you're at it...

Already know English and Russian. The other most useful language would be Spanish. But I'll go with French because

"I love French wine, like I love the French language. I have sampled every language, French is my favorite. Fantastic language. Especially to curse with. Nom de dieu de putain de bordel de merde de saloperie de connard d'enculer ta mère. It's like wiping your arse with silk. I love it."

Couldn't decide between Classical Latin and Japanese.
I'm (pleasantly) surprised anyone picked Polish. Compared to the rest, our language seems so useless.

Imo spanish is the most useful but japanese would be the most fun

Japanese. I've always wanted to go to Japan, so learning Japanese seems like the best choice.

German without a doubt.

Or if I didn't know english, then obviously english.

I chose Japanese, I think it's a beautiful language and I'd LOVE to go there one day!

Arabic. Its grammar is very challenging; even native speakers (professional businessmen) may not know the proper grammer rules.

Just checked the results. No love for Swahili. shakes head sadly

A lot of Otakus here... ¬¬;

What about coding languages? Java, C++, etc.?

German because I like it, though I do like russian too and italian but the last one is easier to learn

Latin

hindi so i could understand my boyfriend better :)

Chinese because I already know Russian, English, and Spanish. Besides, everyone knows China will eventually rule the universe some day ;). If I enjoyed manga/anime, I would, however, probably pick Japanese. Alas, sadly I do not enjoy manga/anime, but I understand why people would pick Japanese.

Chinese definitely. Because after a couple of years, the world is going to get filled up with Chinese (and Indians) everywhere. Billions and billions of them.

Italian, family roots and shit

Finnish. Beautiful country and part of my ancestry.

RUSSIAN

C++

Weird that you may ask this, because I've been considering learning a language lately.

I guess I'd go for Japanese.

Why? Well, I've been thinking about it. I wanted to learn a language which I could use often enough not to lose it, and which would be helpful as well. At first, I seriously considered Russian since it's a language commonly seen on the internet and in gaming-related areas of the web.
I also considered Chinese, German and Spanish.

However, I chose Japanese because I've started watching quite a bit of anime in the past months. I can only watch dubbed ones because I can't focus on the subtitles when watching a video. If I were to learn Japanese, this would no longer be a problem.

Another reason is that Japan is an interesting location I might want to visit one day (along with New Zealand, the UK, and France). Being able to speak, understand, read and write Japanese fluently would be extremely useful in that situation.

My brother in law is from germany and a lot of his family only speaks german, so I'd like to learn german because it would be great to have conversations with his extended family they are lovely people but there is a communication barrier.
