Portugal has a population of just over 10 million, so why is Portuguese spoken by 250 million people around the world? One word: Brazil. It is also the official language of eight countries: Angola, Brazil, Cape Verde, East Timor, Guine-Bissau, Mozambique, Portugal, and São Tome and Príncipe. It is also spoken in the Portuguese islands of Madeiras and Azores… if you're thinking of heading that way.
Portuguese is the third most spoken European language (after English and Spanish) as well as the fastest growing language of Europe (with Spanish). Brazil is currently the 5th largest economy in the world. It therefore makes sense in the global economy to study Portuguese.
