Poder (Can and Be Able To) in Spanish

In Brief

Use a conjugated form of poder followed by an infinitive (the basic verb form, such as hablar or comer): Puedo nadar means “I can swim.” In the present tense, o changes to ue in every form except nosotros/as and vosotros/as: puedo, puedes, puede, podemos, podéis, pueden.

Overview

Poder is one of the most useful Spanish verbs. It lets you say that someone can do something, ask for permission, offer help, or describe what is possible. You will hear it in everyday questions such as ¿Puedes venir? (“Can you come?”) and ¿Puedo pasar? (“May I come in?”).

This is an A1 grammar point: the beginner pattern is simply poder + infinitive. Unlike English can, however, poder is a full verb. It changes to agree with its subject (the person or thing doing the action), and it also has forms for other tenses. Spanish often leaves the subject pronoun unstated because the verb form already identifies the subject: Podemos entrar clearly means “We can come in.”

English uses can for several related ideas. Spanish poder covers many of the same ones—ability, permission, and possibility—but the match is not perfect in every context. Start with the present-tense pattern, then use the later sections as a guide to distinctions you will meet beyond A1.

How It Works

Present-tense forms

The stem is the part of a verb before its ending. In poder, the stem vowel changes from o to ue when the stem is stressed. The nosotros/as and vosotros/as forms keep o.

Subject	Form	Basic meaning
yo	puedo	I can / am able to
tú	puedes	you can (informal singular)
él, ella, usted	puede	he/she can; you can (formal singular)
nosotros/as	podemos	we can
vosotros/as	podéis	you can (informal plural, mainly Spain)
ellos, ellas, ustedes	pueden	they can; you can (plural)

The written accent in podéis marks the stressed syllable. It does not indicate the stem change.

The basic sentence pattern

The second verb stays in the infinitive; only poder is conjugated:

subject + form of poder + infinitive + rest of sentence

• Yo puedo conducir. — I can drive.
• Ana puede venir mañana. — Ana can come tomorrow.
• Podemos reservar una mesa. — We can book a table.

Do not conjugate both verbs. English also uses a base verb after can (“can go,” not “can goes”), so the idea is familiar, although Spanish uses a true infinitive ending in -ar, -er, or -ir.

Object and reflexive pronouns may attach to the infinitive or stand before the conjugated verb:

• ¿Puedo ayudarte? = ¿Te puedo ayudar? — Can I help you?
• No pueden quedarse. = No se pueden quedar. — They cannot stay.

Both positions are standard. When a pronoun is attached, it is written as one word with the infinitive: ayudarte, quedarme, decirlo.

Three core meanings

1. Ability or practical circumstances

Use poder when someone has the ability or the circumstances needed to do something:

• Marta puede nadar. — Marta can swim.
• Hoy no puedo salir. — I cannot go out today.

The second example may describe circumstances rather than a physical skill. Context tells you whether “can” means “know how to,” “be free to,” or “be in a position to.” For a learned skill, Spanish can also use saber + infinitive: Sé nadar means “I know how to swim.” See Usage Notes for the contrast.

2. Permission and requests

Questions with poder commonly ask permission or request action:

• ¿Puedo usar el baño? — May I use the bathroom?
• ¿Puedes cerrar la ventana? — Can you close the window?

As in English, the literal question is about possibility, but its social purpose is a request. ¿Puede…? uses the formal singular form associated with usted. ¿Podría…? (“Could you…?”) is softer and more polite, but it belongs to a later tense.

3. Possibility

Poder can indicate that an event is possible:

• El tren puede llegar tarde. — The train may/can arrive late.
• Puede ser verdad. — It may be true.

In this meaning, English often prefers may, might, or “it is possible,” rather than can. Do not translate word for word without considering the situation.

Questions and negatives

Spanish does not need an equivalent of English do to form questions or negatives.

• Statement: Puedes entrar. — You can come in.
• Question: ¿Puedes entrar? — Can you come in?
• Negative: No puedes entrar. — You cannot come in.

Put no directly before the conjugated verb. In writing, remember both opening and closing question marks: ¿...?

Examples in Context

Spanish	English	Note
¿Puedo ayudarte?	Can I help you?	An offer; pronoun attached to the infinitive
No puedo venir esta noche.	I can’t come tonight.	Circumstances prevent it
¿Puedes hablar más despacio?	Can you speak more slowly?	Informal request to one person
Lucía puede trabajar desde casa.	Lucía can work from home.	Ability or permission from circumstances
¿Podemos entrar?	Can we come in?	Asking permission
Hoy podemos comer fuera.	We can eat out today.	A possible plan
¿Podéis esperar cinco minutos?	Can you wait five minutes?	Informal plural form used mainly in Spain
Usted puede pagar con tarjeta.	You can pay by card.	Formal singular address
No pueden quedarse aquí.	They can’t stay here.	Negative with a reflexive infinitive
¿Me pueden decir la hora?	Can you tell me the time?	Ustedes or an implied plural subject
El paquete puede llegar mañana.	The package may arrive tomorrow.	Possibility, not personal ability
Puede ser una buena idea.	It may be a good idea.	Common expression: puede ser
No te puedo oír.	I can’t hear you.	Pronoun before poder
No puedo abrirlo.	I can’t open it.	Pronoun attached to the infinitive

Common Mistakes

Using the regular stem in every form

• Wrong: Yo podo ir ahora.
• Right: Yo puedo ir ahora.
• Why: Present-tense poder changes o → ue in puedo, puedes, puede, and pueden. Do not confuse podo with a form of podar (“to prune”).

Changing the stem in nosotros or vosotros

• Wrong: Nosotros puedemos entrar.
• Right: Nosotros podemos entrar.
• Why: The stem is not stressed in podemos or podéis, so these forms keep o.

Conjugating the second verb

• Wrong: Ella puede viene mañana.
• Right: Ella puede venir mañana.
• Why: After a conjugated form of poder, use an infinitive: venir, not viene.

Adding a preposition before the infinitive

• Wrong: Puedo a ayudarte.
• Right: Puedo ayudarte.
• Why: Poder connects directly to the infinitive. English “be able to” can tempt learners to insert a, but Spanish does not use it here.

Copying English question structure

• Wrong: ¿Haces puedes venir?
• Right: ¿Puedes venir?
• Why: Spanish forms this question with intonation and question marks; it needs no helping verb equivalent to English do.

Using poder for every learned skill

• Less precise: Puedo nadar when you mean that you have learned how.
• More precise: Sé nadar.
• Why: Saber + infinitive emphasizes knowing how to do something. Poder nadar often emphasizes present ability or circumstances, though context can make either expression natural.

Usage Notes

Poder versus saber

English can can mean either “have the skill” or “be able under the current circumstances.” Spanish often distinguishes them:

Spanish	Natural English meaning	Focus
Sé conducir.	I can drive / I know how to drive.	Learned skill
Puedo conducir hoy.	I can drive today.	Present ability, permission, or circumstances
No sé abrir el archivo.	I don’t know how to open the file.	Lack of know-how
No puedo abrir el archivo.	I can’t open the file.	Something prevents success

The distinction is useful, not absolute. A person may say No puedo nadar because of an injury or because they never learned. Context usually makes the intended meaning clear.

Choosing the form of “you”

Use puedes with tú, for one person addressed informally. Use puede with usted, for one person addressed formally. In Spain, podéis normally goes with informal plural vosotros/as, while pueden goes with formal plural ustedes. Across most of Latin America, ustedes pueden is the normal plural form in both informal and formal situations.

Subject pronouns are usually unnecessary: ¿Puede ayudarme? is grammatically complete. The situation and the verb form often show whether the speaker means formal “you” or “he/she.” State the subject when context does not make it clear.

Requests: direct or softened

¿Puedes…? is ordinary and natural with friends, family, and colleagues in many settings. ¿Puede…? adds formal distance. Adding por favor makes either request more courteous. For a gentler request, Spanish frequently uses the conditional form podría: ¿Podría ayudarme, por favor? (“Could you help me, please?”).

Beyond the Basics / Advanced Use

You do not need to master these points at A1, but they explain forms and meanings you will soon encounter.

Other tenses change the viewpoint

Because poder is a full verb, it can appear in past, future, conditional, and subjunctive forms. The contrast between two common past forms can be meaningful:

• Podía verlo desde mi ventana. — I could see it from my window. This presents an ongoing ability or situation.
• Pude abrir la puerta. — I managed to open the door. In an affirmative completed event, the preterite pude often suggests that the attempt succeeded.
• No pude abrir la puerta. — I could not / was unable to open the door. The attempt did not succeed.

This “managed to” interpretation is common, but context still matters. Learn it as a useful tendency rather than as a mechanical translation rule.

The conditional podría often means “could,” whether for a possibility or a polite request: Podríamos ir en tren (“We could go by train”); ¿Podría repetirlo? (“Could you repeat that?”).

Puede que introduces a clause

When “perhaps” or “it may be that” is followed by a new clause with its own conjugated verb, Spanish often uses puede que + subjunctive. The subjunctive is a verb form used in certain contexts involving possibility, uncertainty, wishes, and other non-asserted ideas:

• Puede que llueva mañana. — It may rain tomorrow.
• Puede que no tengan tiempo. — They may not have time.

Compare this with poder + infinitive when the same subject is understood: Puede llover mañana (“It may rain tomorrow”). The subjunctive forms belong to a later stage of study.

Useful fixed expressions

• puede ser — maybe; that may be; it is possible
• no poder más — to be unable to go on; to have had enough: No puedo más.
• a más no poder — as much as possible / extremely, depending on context

These expressions show why a dictionary translation such as “can” is only a starting point. Learn each one through complete sentences.

Practice Tips

1. Build a six-form rhythm. Say puedo, puedes, puede, podemos, podéis, pueden aloud, stressing the changing stem. Then replace the subject and add one infinitive: puedo salir, podemos salir, pueden salir.
2. Sort examples by purpose. Write three mini-dialogues: one about ability, one asking permission, and one describing possibility. This trains you to connect the same verb with different real-life intentions.
3. Contrast saber and poder. For each skill, make a general sentence and a situation-specific one: Sé conducir, pero hoy no puedo conducir. This prevents the English word can from controlling every choice.
