What is the official language of Brazil?
Portuguese is the first language of the vast majority of Brazilians, but numerous foreign words have expanded the national lexicon. The Portuguese language has undergone many transformations, both in the mother country and in its former colony, since it was first introduced into Brazil in the 16th century. The two countries have largely their spellings, but pronunciations, vocabularies, and the meanings of words have diverged so widely that it now may be easier for some Brazilians to understand Spanish-language films from other Latin American countries than films from Portugal. Italians, Germans, Japanese, and Spanish-speaking immigrants have introduced new words and expressions in Brazilian Portuguese, such as the ubiquitous expression tchau (“farewell”), which was adopted from the Italian ciao. Foreign products and technologies have introduced additional terms.
