4. Spanish
Number of speakers: 392 million

Aside from all of those kids who take it in high school, Spanish is spoken in just about every South American and Central American country, not to mention Spain, Cuba, and the U.S. There is a particular interest in Spanish in the U.S., as many English words are borrowed from the language, including: tornado, bonanza, patio, quesadilla, enchilada, and taco grande supreme.

To say "hello" in Spanish, say "Hola" (OH-la).


3. Hindustani
Number of speakers: 497 million

Hindustani is the primary language of India's crowded population, and it encompasses a huge number of dialects (of which the most commonly spoken is Hindi). While many predict that the population of India will soon surpass that of China, the prominence of English in India prevents Hindustani from surpassing the most popular language in the world. If you're interested in learning a little Hindi, there's a very easy way: rent an Indian movie. The film industry in India is the most prolific in the world, making thousands of action/romance/musicals every year.

To say "hello" in Hindustani, say "Namaste" (Nah-MAH-stay).
