From the southern tip of Argentina to Mexico - and in Spain of course - Spanish transcends borders. In recent decades, many North Americans have taken an interest in learning Spanish, also known as Castilian. The beautiful language of Cervantes and Gabriel Garcia Marquez and of painters El Greco and Frida Kahlo, Spanish is expected to have 500 million speakers worldwide five years from now. People study Spanish out of a love for travel of course, but also out of interest for culture and history. The second most spoken language in the world, Spanish has become an important business language.
