Although European and Brazilian Portuguese have a consistent common base and speakers from the two different regions will understand each other, there are some differences in the way they conjugate the verbs.
European Portuguese speakers use for the 2nd person singular the personal pronoun “tu” and for the 2nd person plural “vós”. Brazilian Portuguese have almost excluded these forms and commonly use “vôce” for singular and “vôces” for plural. In European Portuguese “vôce” and “vôces” are the polite forms, but not in Brazilian Portuguese where these pronouns are the norm. In both variants, when you use "vôce/vôces" the following verb is conjugated in the 3rd person.
In Brazil, “tu” is very little used and it is specific to Gaucho dialect, spoken in the south and northeast. In this dialect, when "tu" is used, the following verb does not conjugate in the 2nd person, singular, as in the standard language, but in the 3rd person, singular.
Still in use in Brazil, the gerund has been largely replaced by "a+infinitive" phrase in Europe:
