Understanding the Subjunctive Mood in Portuguese
The subjunctive mood, or subjuntivo in Portuguese, is used to express situations that are not certain to happen. Unlike the indicative mood, which deals with statements of fact or certainty, the subjunctive is reserved for hypothetical scenarios, wishes, doubts, and uncertainties. Recognizing when to use the subjunctive is crucial for sounding natural and polite in conversation.
Why Use the Subjunctive for Doubt or Uncertainty?
In Portuguese, the subjunctive is often triggered by expressions that convey doubt, disbelief, or lack of certainty. These situations include:
- Expressing doubt or suspicion
- Questioning the truth of a statement
- Describing something that might or might not happen
- Reacting to something that is not a fact
Common Expressions That Trigger the Subjunctive
Several phrases and verbs naturally lead to the use of the subjunctive. Here are some common ones you will encounter:
- Duvidar que (to doubt that)
- Não acreditar que (not to believe that)
- Não achar que (not to think that)
- Não ter certeza que (not to be sure that)
- É possível que (it is possible that)
- É improvável que (it is unlikely that)
- É duvidoso que (it is doubtful that)
These structures are often followed by a verb in the subjunctive because they introduce a sense of uncertainty or doubt about the action or state that follows.
How to Form the Subjunctive
The present subjunctive is formed by taking the first person singular (eu) form of the verb in the present indicative, dropping the final -o, and adding the subjunctive endings. For regular verbs, the endings are:
- -ar verbs: -e, -es, -e, -emos, -em
- -er/-ir verbs: -a, -as, -a, -amos, -am
Let’s see how this works with a few examples:
- Falar (to speak): que eu fale, que você fale, que nós falemos, que eles falem
- Comer (to eat): que eu coma, que você coma, que nós comamos, que eles comam
- Partir (to leave): que eu parta, que você parta, que nós partamos, que eles partam
Examples of Expressing Doubt or Uncertainty
Here are some practical sentences showing how the subjunctive is used to communicate doubt or uncertainty:
- Duvido que ela venha hoje. (I doubt that she will come today.)
- Não acredito que ele saiba a resposta. (I don’t believe he knows the answer.)
- É possível que chova amanhã. (It’s possible that it will rain tomorrow.)
- Não tenho certeza de que eles estejam em casa. (I’m not sure they are at home.)
- É improvável que consigamos terminar a tempo. (It’s unlikely that we will finish on time.)
