good idea: Spanish (you already speak a latin language which might make it easier) or Chinese (Singapore seems THE place to be...)

I should say Chinese and Russian :- 

Wow! thanks for your soon answers

Effectivily Chinese was an idea but I'm not sure I could like the culture.. But SIngapore? Humm i will check that ! Danke Rena!

Russian as well, but I thought russian will be more usefull in special area like Financial companies, no?

What about Portuguese? I've heard that brazil could have a big role in a few years (?)

Portuguese is always a good idea :-) I'am Portuguese iBrazil is able to stabilize and reduce its domestic debt burden, then I think that Brazil is really going to become a shining star, whoever is the president. And the reason is this, and not to segue, but I think that the ascendancy of Asia again, the growth of China, China's extension into the WTO, is very positive news for Latin American, because Latin American is the provider of commodities to the world, and Asia is the biggest consumer of these commodities

Gerne Jessi,

Brazil is part of the BRICS (and will face some GDP growth over the next years) but is struggling internally. China seems more promising despite current difficulties.

Yes, huge amounts of Chinese Foreign Direct Investment went to Brazil (and other LATAM countries) over the last years. A lot of African countries benefit as well.

As a French teacher, I would obviously advise it, especially if you are in Geneva and planning on staying.

I would have loved to learn Russian or Chinese or Hebrew

Any language is a richness so pick anyone, just make sure you use it and practice it extensively or else, you will loose it. It's a muscle. Use it :)

Thanks you all again!

I think I'm gonna try with Portuguese then

What about HINDI.... (One of the most spoken Language in India)... 

"I" in BRIC countries is India..... So may be give a thought about it....

Anyways good luck with any of the new language you pick to learn...

Dear Steven,

I haven't choosed for the moment the language I wil learn, but as I would like to have some lessons I have to find a decision very soon (most of the language school begin the lessons in September).

That's why I've asked the help of the Glocal's community, and I'm glad to see that I was thinking about most of the proposed languages .. excepted Turkish! Why do you think it will be a good idea? Excepted in Europe I didn't know that Turkey was playing a big role in international issues

Anyway that's still to have different point of views !!

It depends on why you want to learn a new language. Business? Fun? Culture? Mental exercise?

Hello Jessica, 

It really depends on many factors. For example: Chinese is the worlds most spoken language (~1000 milion speakers). However, it won't be too useful if you plan to live and work in Europe.

I would say Spanish. It's one of the easiest languages to learn. However I see that you already have knowledge in French so I think the French would be the best choice. It's spoken in many countries not just France. There are ~200 milion French speakers
