How Brazilians use it

A gente makes it easy

In conversation Brazilians often use a gente, which needs no ending: é melhor a gente ir, antes de a gente sair. In casual speech you'll also hear the ending dropped (para eles sair), but in writing it's expected.

It looks like the future subjunctive

For regular verbs the two are the same: falarmos, falarem. They part ways with irregular verbs: para nós fazermos (personal infinitive) but quando nós fizermos (future subjunctive).

In Portugal

The personal infinitive works the same way in Portugal.

Common mistakes

  • NotAntes de vocês sair, fechem a janela.

    ButAntes de vocês saírem, fechem a janela.

    When the infinitive has its own subject, it takes that subject's ending: vocês saírem, nós sairmos.

  • NotLiguei para eles fizerem o trabalho.

    ButLiguei para eles fazerem o trabalho.

    The personal infinitive is never irregular: it's the infinitive plus -mos or -em. Fizerem is the future subjunctive.

  • NotEle trouxe o livro para mim ler.

    ButEle trouxe o livro para eu ler.

    The subject of an infinitive is eu, not mim. Para mim ler is common in speech, but it's marked as wrong.
