enquanto + Future Subjunctive

Enquanto (Futuro Do Subjuntivo)

Level 4

Enquanto + Futuro do Subjuntivo is used to express 'as long as' or 'while' regarding future events. It links two actions: the main action will happen or continue only for the duration of the future condition.

How It Works

In Portuguese, when we talk about a future 'while' or 'as long as', we must use the future subjunctive. This is a distinct feature of Portuguese that separates it from other Romance languages.

1. Formation:
The future subjunctive is typically derived from the 3rd person plural of the Pretérito Perfeito -AR Verbs (or -ER/-IR equivalents). For regular verbs, it looks identical to the personal infinitive, but for irregulars, it changes significantly (e.g., fazer becomes fizer).

2. Usage:

3. Register:
This pattern is essential for both casual conversation and formal writing. It is not optional; using the present tense for future 'while' clauses is considered grammatically incorrect in Portuguese.

  1. Enquanto você não fizer o dever de casa, não poderá sair.

    As long as you don't do your homework, you won't be able to go out.

    Word by Word: While you not do (future subjunctive) the homework, not will-be-able to-go-out.

    The irregular verb 'fazer' becomes 'fizer' in the future subjunctive to show a future condition.

  2. Viajaremos pelo mundo enquanto tivermos saúde.

    We will travel the world as long as we have health.

    Word by Word: We-will-travel through-the world while we-have (future subjunctive) health.

    The verb 'ter' becomes 'tivermos' for the 'nós' form in the future subjunctive.

  3. Enquanto eu for o seu chefe, você seguirá as regras.

    As long as I am your boss, you will follow the rules.

    Word by Word: While I be (future subjunctive) the your boss, you will-follow the rules.

    The verb 'ser' becomes 'for' in the future subjunctive.

  4. Fique aqui enquanto eu for ao mercado.

    Stay here while I go to the market.

    Word by Word: Stay (imperative) here while I go (future subjunctive) to-the market.

    Here, 'enquanto' is used with an imperative in the main clause to give a command for a future duration.

Common Mistakes

  • Using the Present Subjunctive (Spanish influence).

    Enquanto ele esteja aqui, eu não falo.
    Enquanto ele estiver aqui, eu não falo.

    In Portuguese, 'enquanto' for future events requires the future subjunctive (estiver), not the present subjunctive (esteja).

  • Using the infinitive for irregular verbs.

    Enquanto você fazer isso, nada vai mudar.
    Enquanto você fizer isso, nada vai mudar.

    Learners often use the base infinitive 'fazer', but irregular verbs must use their specific future subjunctive stem (fizer).
