Understanding the Portuguese Subjunctive: An Overview
The portuguese subjunctive is a verb mood that expresses doubt, uncertainty, desires, emotions, hypothetical situations, and subjective opinions. Unlike the indicative mood, which states facts and objective reality, the subjunctive conveys what is not concrete or is influenced by feelings and attitudes. It is essential for conveying subtle meanings and politeness in both spoken and written Portuguese.
The subjunctive appears in three primary tenses:
- Present Subjunctive (Presente do Subjuntivo)
- Imperfect Subjunctive (Pretérito Imperfeito do Subjuntivo)
- Future Subjunctive (Futuro do Subjuntivo)
Each tense serves different communicative purposes, and mastery over all three is crucial for fluency.
How to Form the Portuguese Subjunctive
Understanding the conjugation patterns is the first step to effectively using the portuguese subjunctive. The formation depends on the verb ending in the infinitive (-ar, -er, -ir) and varies slightly between regular and irregular verbs.
Present Subjunctive Formation
The present subjunctive is formed by taking the first person singular (eu) form of the present indicative, removing the -o ending, and adding the subjunctive endings:
- -ar verbs: -e, -es, -e, -emos, -eis, -em
- -er and -ir verbs: -a, -as, -a, -amos, -ais, -am
Example with the verb falar (to speak):
- eu fale
- tu fales
- ele/ela fale
- nós falemos
- vós faleis
- eles/elas falem
Example with the verb comer (to eat):
- eu coma
- tu comas
- ele/ela coma
- nós comamos
- vós comais
- eles/elas comam
Imperfect Subjunctive Formation
The imperfect subjunctive is derived from the third person plural of the preterite indicative. To form it, remove the -ram ending and add:
- -ar, -er, -ir verbs: -sse, -sses, -sse, -ssemos, -sseis, -ssem
Example with the verb falar:
- eu falasse
- tu falasses
- ele/ela falasse
- nós falássemos
- vós falásseis
- eles/elas falassem
Future Subjunctive Formation
The future subjunctive is unique to Portuguese and is formed from the third person plural of the preterite indicative by removing the -ram ending and adding:
- All verbs: -r, -res, -r, -rmos, -rdes, -rem
Example with the verb falar:
- quando eu falar
- quando tu falares
- quando ele/ela falar
- quando nós falarmos
- quando vós falardes
- quando eles/elas falarem
When and Why to Use the Portuguese Subjunctive
The portuguese subjunctive is triggered by specific contexts, often linked to uncertainty, emotion, or non-factual statements. Below are the most common scenarios where the subjunctive is required:
Expressing Wishes, Desires, and Requests
Use the subjunctive after verbs and expressions that convey hopes or wishes:
- Espero que você venha amanhã. (I hope you come tomorrow.)
- Quero que eles estudem para a prova. (I want them to study for the exam.)
Expressing Doubt and Uncertainty
The subjunctive is used when the truth of a statement is uncertain or questioned:
- Não acredito que ele saiba a resposta. (I don’t believe he knows the answer.)
- Duvido que eles tenham terminado o trabalho. (I doubt they have finished the work.)
Giving Recommendations and Suggestions
When advising or suggesting an action, the subjunctive is used:
- É importante que você faça exercícios diariamente. (It’s important that you exercise daily.)
- Recomendo que vocês leiam este livro. (I recommend that you read this book.)
After Conjunctions Expressing Condition, Purpose, or Time
The future subjunctive frequently appears after conjunctions such as quando (when), se (if), assim que (as soon as):
- Se ele vier, avisarei você. (If he comes, I will inform you.)
- Quando nós terminarmos o projeto, celebraremos. (When we finish the project, we will celebrate.)
Common Mistakes Learners Make with the Portuguese Subjunctive
Many learners struggle with the portuguese subjunctive due to its complexity. Here are some common pitfalls to watch out for:
- Confusing indicative with subjunctive: Using the indicative where the subjunctive is required changes the meaning and can sound unnatural.
- Incorrect conjugations: Irregular verbs and stem changes often cause errors; consistent practice is key.
- Omitting the subjunctive after trigger phrases: Phrases like é importante que always require the subjunctive.
- Overusing the subjunctive: Not every hypothetical or emotional expression requires it; understanding context is essential.
