Lots of them, depending on which language you want to learn.

There is no one world language (even Esperanto did not become popular). Some of the commercially important languages (apart from English) are German (many parts of Europe), French (many parts of Europe and Africa), Spanish (some parts of Europe, Latin America and even US), Chinese and Japanese. You can learn one of these based on which region you would want to work in and also which is being taught near your place.

Having English and Spanish down, you're pretty good.  I would recommend Chinese because it is obviously an up and coming nation that will have a huge global influence on everything from politics to trade to just about everything.  If not Chinese, I would look into Arabic for similar reasons (spanning a variety of countries).  Either will make you incredibly marketable!

Chinese. China is the most populated country in the world and will continue to grow exponentially. If you have any interest in the business world, knowing Chinese will be an amazing asset.\n\nIt is THE one language to learn - don't bother with issues like ease or how cool Japanese aname is. They're not relevant to the question.

Spanish - a huge percentage of the world's population speaks Spanish.  Then French.

Spanish is more commonly used by a growing Hispanic population.  In some parts of the country, it's the main language used, whether you like it or not.  \n\nIn terms of worldwide, my understanding is that English, Chinese and Spanish are the most used languages.  Definitely true in business.

It depends on your objectives.   If you want to showcase yourself as being proficient in a more "exotic" yet economically-in-demand language, where there are otherwise few qualified professionals available in the job market, then I would say go for Japanese, Chinese, Portuguese, or Arabic.    On the other hand, if the idea were to be able to communicate with a greater number of people speaking an idiom, then I would definitely say Spanish or Chinese.    Finally, if you have a targeted geographical region in mind then obviously your choices are already more narrowly defined.    For instance, in Europe I would consider (in addition to English, of course) French and/or German.     … But if you really insist on a single answer, then I would say, considering everything (e.g. the number of people speaking the language, its overall economic and political viability, the lack of language-proficient individuals in the job market) “Chinese” is most likely the one true language opportunity of the future for an English-speaking person.

French because it gives you a wide choice for a career and languages are always sought after. Plus I like languages. Geography limits you whilst French you can do what ever job and get higher pay for it!

Mandarin Chinese is the most prevalent language.\n\nhttp://en.wikipedia.org/wiki/List_of_languages_by_total_speakers

The Summer Institute for Linguistics (SIL) Ethnologue Survey (1999) lists the following as the top languages by population:\n(number of native speakers in parentheses)\n\nChinese* (937,132,000) \nSpanish (332,000,000) \nEnglish (322,000,000) \nBengali (189,000,000) \nHindi/Urdu (182,000,000) \nArabic* (174,950,000) \nPortuguese (170,000,000) \nRussian (170,000,000) \nJapanese (125,000,000) \nGerman (98,000,000) \nFrench* (79,572,000) \n\nHowever, English is a second language for many people, and that isn't factored in.  What to learn depends on what you want to do.  Business on the west coast, for example, you'd want Spanish, Japanese, or possibly Mandarin or Hindi.  I speak French but I've decided that it was a waste.  Everyone who speaks French is rude for the most part, and will insult you for speaking their language poorly.  \n\nSee the website below if you want to look at more stats on the most widely spoken languages.  I'm taking Mandarin now, and am glad to see its spoken by more people than any other language.
