Portuguese is the official language of nine countries and the main language of eight of them, making the concept of it as a "world language" quite applicable. It is also widely spoken in various other countries, including parts of Asia, North America and South Africa. It is the fifth widely used language in the world, the main language of as many as two hundred seventy million people across the world. Some of my clients just learn the language for personal reasons. Nevertheless, knowing Portuguese can open doors to understand the culture and history of one of the oldest countries, Portugal. It can also lead you to outstanding professional opportunities in some of the most prospective economies such as Brazil, Angola and Mozambique. All of these countries also have amazing climates as well as astonishing natural and urban landscapes, which make them among the most sought-after and rewarding tourist destinations.
