The Portuguese language therefore serves more than 250 million people daily, who have direct or indirect legal, juridical and social contact with it, varying from the only language used in any contact, to only education, contact with local or international administration, commerce and services or the simple sight of road signs, public information and advertising in Portuguese.
Beginning in the 16th century, the extensive contacts between Portuguese travelers and settlers, African and Asian slaves, and local populations led to the appearance of many pidgins with varying amounts of Portuguese influence.
As each of these pidgins became the mother tongue of succeeding generations, they evolved into fully fledged creole languages, which remained in use in many parts of Asia, Africa and South America until the 18th century.
Some Portuguese-based or Portuguese-influenced creoles are still spoken today, by over 3 million people worldwide, especially people of partial Portuguese ancestry.
A notable aspect of the grammar of Portuguese is the verb. Morphologically, more verbal inflections from classical Latin have been preserved by Portuguese than by any other major Romance language. Portuguese and Spanish share very similar grammar. Portuguese also has some grammatical innovations not found in other Romance languages (except Galician and Fala):Todos os seres humanos nascem livres e iguais em dignidade e em direitos. Dotados de razão e de consciência, devem agir uns para com os outros em espírito de fraternidade.All human beings are born free and equal in dignity and rights. They are endowed with reason and conscience and should act towards one another in a spirit of brotherhood.
