The Portuguese language spread worldwide in the 15th and 16th centuries in Brazil, Africa and along the coasts of Asia. Today, Portuguese is the official language of several independent states and is also spoken by many people as a minority or second language. In addition to Portuguese proper, there are about twenty creole languages on a predominantly Portuguese basis.
Portuguese is the sole official language in Angola, Brazil, Mozambique, Portugal and São Tomé and Príncipe. Together with other languages, Portuguese is the official language in East Timor (together with Tetum), Macau (together with Chinese) and Equatorial Guinea (together with French and Spanish).
The Brazilian and African dialects have some peculiarities compared to European Portuguese, mainly due to the influence of indigenous and African languages respectively and to spatial isolation.
