Introduction
Learning how to express possibility is essential for speaking Spanish naturally. This article explains how to use Puede que to say that something may happen, how it compares to other ways to express possibility, and how to form sentences correctly with the subjunctive mood. Clear examples and usage notes will help English-speaking learners use puede que with confidence.
What is Puede que and why use it?
Puede que is a common Spanish expression used to indicate that something might happen or might be true. It is similar to English phrases like it may be, it might happen, or perhaps. Native speakers use it frequently in spoken and written Spanish when they want to express uncertainty or a possibility without committing to a definite outcome.
A key feature of puede que is that it requires the subjunctive mood in the verb that follows. This is important because the subjunctive signals doubt, uncertainty, or non-assertion—exactly the nuance we want when saying something may happen.
Structure and grammar rules
Basic sentence structure
The basic structure is: Puede que + [verb in present subjunctive]. The subject of the verb after puede que is the person or thing that may or may not perform the action.
Example:
Puede que venga mañana.
Translation: He or she may come tomorrow.
Why the subjunctive?
The subjunctive mood is used because puede que expresses uncertainty. In Spanish, when the main clause indicates doubt, possibility, desire, or emotion, the subordinate clause usually takes the subjunctive. Think of the subjunctive as the grammatical signal that the event is not certain.
So after puede que you will use verbs like venga, sea, tenga, vaya, etc., rather than viene, es, tiene, va.
Common subjunctive forms after puede que
Present subjunctive is the most common: venga, hable, coma, tenga. You may also see past subjunctive when referring to hypothetical or less likely situations in the past, depending on context: hubiera venido, fuera, tuviera.
Examples:
Puede que llueva esta tarde. (present subjunctive)
Puede que no lo supiera. (imperfect subjunctive, if referring to a past possibility)
How to form the present subjunctive after Puede que
Regular verbs
To form the present subjunctive for regular verbs, start with the yo form of the present tense, drop the -o, and add the opposite endings.
For -ar verbs: e, es, e, emos, éis, en.
For -er and -ir verbs: a, as, a, amos, áis, an.
Examples with Puede que:
hablar -> hable: Puede que hable con ella más tarde.
comer -> coma: Puede que coma antes de salir.
vivir -> viva: Puede que viva cerca de aquí.
Irregular verbs
Irregular verbs in the present subjunctive follow the same principle but with irregular stems. Common irregulars include ser -> sea, ir -> vaya, haber -> haya, estar -> esté, saber -> sepa, tener -> tenga.
Examples:
Puede que sea difícil.
Puede que vaya al cine.
Puede que haya un problema.
Examples in different tenses and contexts
Talking about present or future possibility
Most of the time you will use the present subjunctive to talk about present or future possibilities.
Examples:
Puede que no llegue a tiempo.
Puede que ellos no sepan la noticia.
Puede que empecemos la reunión sin él.
Talking about past possibility
When referring to a past possibility, Spanish can use the present perfect/subjunctive or the past subjunctive depending on nuance. Two options:
Option 1: Puede que + haya + past participle (present perfect subjunctive) to express that something may have happened recently.
Example:
Puede que haya terminado ya. (He or she may have finished already.)
Option 2: Puede que + imperfect subjunctive to express a past possibility often with some distance or doubt.
Example:
Puede que no lo entendiera bien. (He or she may not have understood it well.)
Negative forms and nuance
Saying that something may not happen
To say that something may not happen, place no before puede que or before the verb after it. Both options are common, but the standard form is no puede que + subjunctive. In practice, native speakers usually say no + puede que + subjunctive.
Examples:
No puede que sea verdad. (It may not be true.)
No puede que vengan hoy. (They may not come today.)
Using tal vez, quizás, and a lo mejor for comparison
Other ways to express possibility include tal vez, quizás, and a lo mejor. Note the grammar differences.
tal vez and quizás often require the subjunctive but can also use the indicative when probability is higher:
Tal vez venga mañana. (subjunctive)
Tal vez viene mañana. (indicative, less common to show more certainty)
a lo mejor is followed by the indicative, not the subjunctive:
A lo mejor viene mañana.
Compared with these, puede que is more explicitly tied to the subjunctive and tends to sound slightly more formal or neutral than tal vez or quizás.
Common mistakes to avoid
Using the indicative after puede que
Do not use the indicative: strong error would be Puede que viene mañana. The correct form is Puede que venga mañana. Always use the subjunctive after puede que.
Confusing puede and puede que
Do not confuse the simple verb puede (from poder) used alone with puede que. When you say puede followed by an infinitive, the structure and meaning differ.
Example with puede + infinitive:
Puede llover. means It can rain or It is possible that it will rain, and uses the infinitive rather than the subjunctive. This is a more impersonal and concise way to say the same idea.
Example with puede que:
Puede que llueva. This requires llueva (subjunctive).
Practical tips for learners
When to choose puede que over other expressions
Use puede que when you want to emphasize uncertainty and use a neutral, widely understood expression that fits both spoken and written Spanish. It is especially useful when you want to avoid specifying the subject with an impersonal verb form, or when the clause structure flows better with a subordinate clause introduced by que.
Listening and speaking practice
Pay attention to how native speakers use puede que in conversation, news, and podcasts. Notice the verb forms that follow. Practicing with short, realistic phrases helps internalize the subjunctive pattern.
Simple practice ideas:
Listen for puede que in radio reports or interviews.
Repeat example sentences aloud to practice subjunctive pronunciation.
Usage and cultural notes
In many Spanish-speaking countries, puede que is a neutral and common way to express possibility. It does not carry strong formality; you will hear it in casual conversations as well as in formal speech. However, casual speakers may sometimes prefer tal vez or a lo mejor depending on rhythm and personal preference.
Also note regional variation: some speakers might use the indicative with tal vez more often than others, but the rule for subjunctive after puede que remains consistent across regions.
Quick reference: Forms and examples
Present possibility: Puede que + present subjunctive
Example: Puede que salga tarde.
Past possibility (recent): Puede que + haya + past participle
Example: Puede que haya perdido el tren.
Past possibility (hypothetical): Puede que + imperfect subjunctive
Example: Puede que no entendiera la explicación.
Conclusion
Puede que is a versatile expression to express possibility in Spanish and always calls for the subjunctive mood. Use it to talk about things that might happen now, in the future, or possibly happened in the past when combined with the appropriate subjunctive form. Familiarity with puede que and related expressions will make your Spanish sound more natural and precise when discussing uncertainty.
