But that age, there aren't school for the all people, so this process was slow. To Century 20, after independece of Brazil, the Tupi was speaked in the cities of the interior. Nowadays teh Tupi suffered evolution and is speaking in the Amazon region, by population riverside or indigenous. The Portuguese speaked in Brazil, is more diferent than Europen Portuguese, because there is influences of the Tupi, by the vocabulary, phonetics, and the form think (the main base to study languages, I think).
