Understanding the Future Subjunctive in Portuguese
The future subjunctive (futuro do subjuntivo) is a verb mood used exclusively in Portuguese and Galician, setting it apart from many other Romance languages. It expresses actions or events that are uncertain or dependent on a future condition. Unlike the indicative mood, which states facts, or the simple future, which predicts events, the future subjunctive is used for hypothetical or conditional scenarios occurring in the future.
What Is the Future Subjunctive?
The future subjunctive is a verb form used primarily after certain conjunctions and expressions that indicate doubt, uncertainty, or conditionality related to future events. Its role is to describe actions that might happen if a particular condition is met.
- Example in English: “If I go to the party, I will have fun.”
- Portuguese equivalent: “Se eu for à festa, vou me divertir.”
Here, for is the future subjunctive form of the verb ir (to go).
Why Is the Future Subjunctive Important?
Understanding and correctly using the future subjunctive is essential for:
- Expressing future conditions and possibilities accurately
- Comprehending native speech and writing, where this tense is frequently used
- Improving overall fluency and grammatical precision
Failing to grasp this mood can lead to misunderstandings or awkward phrasing, especially in formal or written Portuguese.
How to Form the Future Subjunctive in Portuguese
The future subjunctive is formed differently than other tenses, but it follows a clear pattern once understood.
Basic Formation Rules
To form the future subjunctive:
- Start with the third person plural (eles/elas) form of the verb in the simple past (preterite) tense.
- Remove the ending -am from this form.
- Add the appropriate future subjunctive ending.
Interestingly, the endings for the future subjunctive are the same as the infinitive form for regular verbs.
Examples of Regular Verbs
| Verb | 3rd Person Plural Preterite | Remove -am | Future Subjunctive Form (Eu) | English Translation |
|---|---|---|---|---|
| Falar (to speak) | Falaram | Falar- | Falar | If I speak |
| Comer (to eat) | Comeram | Comer- | Comer | If I eat |
| Partir (to leave) | Partiram | Partir- | Partir | If I leave |
Examples of Irregular Verbs
Irregular verbs also follow this pattern but have unique preterite forms. For example:
- Ser (to be): Eles foram → Future subjunctive: for
- Ir (to go): Eles foram → Future subjunctive: for
- Ter (to have): Eles tiveram → Future subjunctive: tiver
- Fazer (to do/make): Eles fizeram → Future subjunctive: fizer
Memorizing these irregular forms is essential because they are commonly used in everyday conversation.
When and How to Use the Future Subjunctive in Portuguese
The future subjunctive is not a tense you use freely; it appears in specific grammatical contexts. Learning these contexts helps learners apply the future subjunctive correctly and naturally.
Common Conjunctions That Require the Future Subjunctive
The future subjunctive often follows conjunctions expressing conditions or time, such as:
- Se (if)
- Quando (when)
- Assim que (as soon as)
- Enquanto (while, as long as)
- Logo que (as soon as)
- Depois que (after)
Example:
Se você estudar, passará no exame.
(If you study, you will pass the exam.)
Expressing Future Conditions
Use the future subjunctive to express conditions that might happen in the future, often in “if-then” clauses.
- Se eu for ao mercado, comprarei frutas.
(If I go to the market, I will buy fruits.) - Quando ela chegar, começaremos a reunião.
(When she arrives, we will start the meeting.)
Use in Relative Clauses Referring to Future Events
The future subjunctive can also appear in relative clauses when referring to something that may happen in the future.
Qualquer pessoa que venha à festa será bem-vinda.
(Anyone who comes to the party will be welcome.)
