Poder: can, can't, and the polite Peruvian request
*Poder* takes a bare infinitive: *puedo hablar*, *no puedes comer*, *¿podemos ir?* It covers three jobs English splits between "can" and "may" — ability, possibility and permission. In Peru the question form is also the standard polite request: *¿Me puede ayudar?* to a stranger, *¿me puedes ayudar?* to someone you already call *tú*.
Draft copy. Every claim needs a native-speaker check before publishing — the byline is what makes this citable, so it has to be earned.
The shape
Poder + infinitive. Nothing between them, no que, no second conjugated verb.
- Yo puedo hacer la comida.
- Ella no puede comer ensalada.
- ¿Puedes pagar la cuenta?
English does the same thing — “I can make lunch” — so the structure transfers cleanly. The mistake is not structural; it is puedo de hacer or puedo que hago, both imported from other languages. Neither exists.
The conjugation, and the one letter that changes
| yo | puedo |
| tú | puedes |
| usted / él / ella | puede |
| nosotros / nosotras | podemos |
| ustedes / ellos / ellas | pueden |
The o turns into ue everywhere except nosotros. That gap is the whole pattern — it is the same shape as querer, dormir and volver, so learning it once here saves you learning it four more times.
No vosotros form is listed because nobody in Peru uses one.
Three jobs, one verb
English splits these between “can” and “may”. Spanish does not.
| Use | Example |
|---|---|
| Ability | Puedo hablar español. |
| Possibility | Él puede estar cansado. — he may be tired |
| Permission | ¿Puedo comer un poco de tu pastel? |
The second one catches people out. Carlos puede ser educado is not “Carlos is able to be polite” — it is “Carlos may well be polite”, a guess about him. Context does the work, and in practice it is almost never ambiguous.
¿Puede? or ¿puedes? — this is a register choice
In Peru the question form of poder is the everyday polite request, the way “could you” is in English. Which one you pick says who you think you are talking to.
- ¿Me puede ayudar, por favor? — a stranger, someone older, anyone behind a counter or a desk. This is the default with people you have not met.
- ¿Me puedes ayudar? — a friend, a colleague you already tutear, someone your own age in an informal setting.
Getting it wrong is not a disaster in either direction, but usted with a stranger is the safe default in Lima, and the one that never lands badly.
Requests worth having ready:
- ¿Me puede repetir, por favor?
- ¿Puede hablar más despacio?
- ¿Me puede llevar a Miraflores? — to a taxi driver
- ¿Puedo pagar con tarjeta?
No puedo is a complete answer
No puedo on its own is a normal, polite refusal — “I can’t”. You do not have to justify it, and Peruvians usually soften it rather than explain it:
- No puedo, disculpe.
- Ahorita no puedo.
Ahorita means “in a moment” or “just now” depending on the sentence, and it buys you time in either direction.
Try it
- Can you (formal) repeat that?
- We can’t have dinner at ten.
- Raúl can’t eat oranges — he’s allergic.
- May I go to Jorge’s house?
→ 1 ¿Me puede repetir? · 2 No podemos cenar a las diez · 3 Raúl no puede comer naranjas, es alérgico · 4 ¿Puedo ir a la casa de Jorge?

Poder, and who you are talking to
Seven questions on the conjugation, the infinitive that follows it, and the register choice between ¿puedes? and ¿puede?
-
1Nosotros ___ cenar a las diez.
Answer
podemos — *Nosotros* is the one form where the *o* does not become *ue*. *Podemos*, never *puedemos*.
-
2Which sentence is built correctly?
Answer
Puedo hacer la cena. — *Poder* takes a bare infinitive with nothing in between — no *de*, no *que*, no gerund. English does the same thing with “can”.
-
3You want to ask a taxi driver you have never met to take you to Barranco. You say:
Answer
¿Me puede llevar a Barranco? — *Usted* is the safe default with a stranger in Lima, so *¿me puede...?* *¿Me puedes?* is for people you already call *tú*.
-
4¿Ustedes ___ comer cerdo?
Answer
pueden — *Ustedes* takes *pueden*. In Peru *ustedes* covers every plural “you”, formal or not — there is no *vosotros*.
-
5Él puede estar cansado. This sentence is about:
Answer
a possibility — Here *poder* means “may” — he might be tired. *Poder* covers ability, possibility and permission where English splits between can and may.
-
6Someone is speaking too fast for you. The most useful thing to say:
Answer
¿Puede hablar más despacio, por favor? — It names the problem and asks for the fix, in the *usted* form a stranger expects. The others either only complain or drop into *tú*.
-
7Raúl can't eat oranges — he's allergic.
Answer
Raúl no puede comer naranjas, es alérgico. — *Raúl* is third person, so *puede*, and the *no* sits in front of it. The verb after stays in the infinitive.
