Overview: expressing possibility in Portuguese
Both É possível que and Pode ser que introduce clauses that express uncertainty, probability, or possibility. They are often followed by verbs in the subjunctive mood because the speaker is not asserting a fact but suggesting something that might happen or might be true.
The subjunctive is used after many impersonal expressions, verbs of doubt, desire, emotion, and possibility. Recognizing when to use the subjunctive is key to using both expressions correctly.
Form and structure
É possível que
Form: É possível que + [subjunctive verb]
This is an impersonal construction built from the verb ser. It expresses that something is possible in a general or objective way. The emphasis is on the possibility as a fact or assessment rather than on the agent who makes the possibility likely.
Examples:
É possível que ele não venha hoje.
É possível que chova à tarde.
Pode ser que
Form: Pode ser que + [subjunctive verb]
This uses the impersonal form of poder, emphasizing the potential or probability of a situation. It often sounds more conversational and slightly less formal than É possível que. Like É possível que, it is followed by the subjunctive because it conveys uncertainty.
Examples:
Pode ser que ele não venha hoje.
Pode ser que chova à tarde.
Why the subjunctive? Quick grammar refresher
When a clause expresses doubt, uncertainty, or non-factual information, Portuguese uses the subjunctive mood. Both expressions introduce subordinate clauses viewed as hypothetical or uncertain, so the subordinate verb appears in the present subjunctive when the main clause is in the present or future context.
Present subjunctive formation for regular verbs:
Eu: -ar verbs → e, -er/-ir verbs → a
Ex.: falar → que eu fale, comer → que eu coma, partir → que eu parta
Comparison: nuance and register
Formality
É possível que is neutral to slightly more formal and often used in writing, news, and polite conversation. It states possibility in a somewhat objective tone.
Pode ser que is more colloquial and common in everyday speech. It expresses possibility with a conversational feel.
Emphasis and speaker perspective
É possível que places the focus on the idea of possibility itself. It can convey a considered or slightly detached assessment.
Pode ser que highlights potentiality or likelihood from the speaker’s viewpoint, sometimes implying a tentative guess.
Compare the tone:
É possível que o trânsito esteja ruim hoje. (A considered possibility, maybe based on a report.)
Pode ser que o trânsito esteja ruim hoje. (A casual guess, perhaps based on past experience.)
Common contexts and examples
Weather and immediate predictions
Both expressions are frequently used to talk about weather or short-term predictions.
É possível que amanhã faça sol.
Pode ser que amanhã faça sol.
Speculation about people or plans
Use either to speculate about someone’s intentions or plans. In spoken Portuguese, pode ser que may feel more natural.
É possível que ela já tenha saído.
Pode ser que ela já tenha saído.
Responding to news or rumors
When reacting to uncertain information, both work well. Slight nuance: é possível que can sound more cautious; pode ser que can sound more conversational.
É possível que a reunião tenha sido cancelada.
Pode ser que a reunião tenha sido cancelada.
Negative constructions
When denying or expressing improbability, both can be negated but keep their structure and still require the subjunctive.
Não é possível que ele tenha feito isso.
Pode não ser que ele tenha feito isso. (Less common; more natural: É pouco provável que ele tenha feito isso.)
Verb tenses after these expressions
Most often you will see the present subjunctive in subordinate clauses after these expressions when referring to present or future possibilities.
Present/future possibility: É possível que ele venha amanhã. / Pode ser que ele venha amanhã.
If you refer to a past possibility or conjecture about the past, use the past subjunctive (pretérito imperfeito do subjuntivo) or the present perfect subjunctive (if needed) depending on nuance.
Past possibility: É possível que ele tivesse esquecido. (Less common; often use é possível que ele tenha esquecido.)
Common past conjecture: Pode ser que ele tenha esquecido.
Note: In many spoken contexts, Brazilians prefer the compound subjunctive like tenha esquecido to conjecture about recent past events.
Examples with conjugations and explanations
Present subjunctive examples
É possível que eu chegue tarde. (The speaker thinks it might happen.)
Pode ser que eu chegue tarde. (A casual way to say the same.)
Past conjecture (present perfect subjunctive)
É possível que ele tenha perdido o avião. (The possibility refers to a past event and the speaker uses present perfect subjunctive.)
Pode ser que ele tenha perdido o avião. (Casual speculation about the past.)
Conditional nuance
É possível que você consiga um desconto se falar com o gerente. (Here possibility depends on a condition.)
Pode ser que você consiga um desconto se falar com o gerente. (Slightly more informal, same meaning.)
Common collocations and variations
Other similar expressions you will hear include talvez, pode ser, talvez seja, é provável que, and é improvável que. They differ in degree of certainty.
Comparative scale:
Talvez / Pode ser que → tentative possibility
É possível que → neutral possibility
É provável que → higher probability
Usage tips for learners
1. Learn the present subjunctive forms. Both structures almost always trigger the subjunctive in subordinate clauses.
2. Match register to context: use é possível que in more formal or written contexts and pode ser que in casual conversation.
3. Listen to native speakers: watch Brazilian news for frequent use of é possível que and everyday TV or podcasts for pode ser que.
4. When talking about past possibilities, prefer the compound subjunctive like tenha + past participle for spoken Brazilian Portuguese.
Cultural and usage notes
Brazilian Portuguese favors conversational shortcuts and softer tones in casual speech. You will often hear speakers use pode ser que or even just pode ser at the end of a sentence as a standalone response meaning maybe. In formal writing, official reports, or news language, é possível que appears more often because of its neutral, impersonal tone.
Examples of colloquial short forms:
– Vai chover?
– Pode ser. (Maybe.)
In contrast, a meteorologist on TV might say:
É possível que ocorram pancadas de chuva no período da tarde.
Common mistakes and how to avoid them
Mistake 1: Using indicative after these expressions. Since they convey uncertainty, using the indicative often sounds incorrect.
Incorrect: É possível que ele vem amanhã. → Correct: É possível que ele venha amanhã.
Mistake 2: Forgetting the subjunctive after pode ser que because the phrase feels colloquial. Practice the verb forms until the subjunctive comes naturally.
Mistake 3: Overusing one phrase. While both are correct, varying your language will make you sound more fluent and appropriate across registers.
Short practice ideas (without exercises)
To internalize usage, notice how native speakers use these expressions in context. When reading news, underline occurrences of é possível que. When listening to podcasts or conversations, note how often people say pode ser que or shorten it to pode ser.
Conclusion
Both É possível que and Pode ser que express possibility and require the subjunctive in the subordinate clause. Use é possível que for a neutral or slightly formal tone and pode ser que for everyday, conversational speech. Paying attention to subjunctive forms and register will help you use these expressions naturally in Brazilian Portuguese.
