are these sentences in my book wrong?

Question

From experience I know that language books can be wrong and I've come across two sentences in my Spanish book;

• *Podemos ir a la playa

• Qué podemos hacer*

Aren't the sentences supposed to be:

• Podemos va a la playa

• Qué podemos hace

Answer 1

The sentences in the book are correct. The verb that is conjugated is "poder," and ""ir" and "hacer" are in the infinitive form and do not require conjugation. Hope this helps.

but i thought that in sentences where the conjugation of verbs are not necessary it is supposed to be conjugated in 3rd person singular? ex. Dont talk wiuld be no habla. - vengamujer, Dec 14, 2012

LaBurra is right, you need the infinitive form in both cases. - Cordobesa, Dec 14, 2012

There, you´re talking about impersonal and general prohibitions, and are correct. But that is not the case in your sentences. (Yo´s put in for clarity, not because they´re needed).

I go -- Yo voy.

I can -- Yo puedo.

I can go -- Yo puedo ir.

I am able to go -- Yo puedo ir (same as above).

I will be (or am going to be) able to go. Yo voy a poder ir .

Note only the initial verb is conjugated.

hope that helps.
