Ability and requests (poder)

Expressing Ability and Permission

To talk about what you are able to do, or to ask for permission, use the verb poder (can / to be able to) followed by an infinitive.

Just like querer, poder is a stem-changing verb. The o in the stem changes to ue in most forms, except for nosotros/nosotras:

PronounPoder (can / to be able to)
yopuedo
puedes
él / ella / ustedpuede
nosotros / nosotraspodemos
ellos / ellas / ustedespueden

Remember the rule for using two verbs together: conjugate the first verb to match the speaker (poder), and leave the second action verb in its dictionary form:

I cannot go to the party.
No puedo ir a la fiesta.
We can wait here with her.
Podemos esperar aquí con ella.
May I come into the room?
¿Puedo pasar al cuarto?

Making Polite Requests

You can also use poder as a friendly, natural way to ask someone for a favor. Simply frame it as a question and add por favor (please).

Use the form (puedes) for friends and people you know well:

Can you come tomorrow, please?
¿Puedes venir mañana, por favor?

Use the usted form (puede) for polite, formal situations:

Can you sign the document, please?
¿Puede firmar el documento, por favor?
