Questions & Answers about Quiero vaciar la caja en mi cuarto.

Why is the verb vaciar in the infinitive form here?

In Spanish, after Quiero (meaning "I want"), you use the infinitive form of the verb. It's a common structure: Quiero + [infinitive]. So you say Quiero vaciar rather than something like "Quiero vacío."

Can I say Quiero vaciar la caja a mi cuarto instead of en mi cuarto?

Generally, a indicates movement to a destination, whereas en indicates location in or at a place. Using a would sound like you intend to empty the box toward or to your room, which is not how Spanish speakers normally express doing the action in the room.

Is Quiero vaciar la caja a complete thought on its own?

Yes, you could just say Quiero vaciar la caja if it’s clear from context where you want to empty it. However, en mi cuarto adds the specific location.

Could I replace la caja with a pronoun and say Quiero vaciarla en mi cuarto?

Absolutely. If it’s clear from context that la refers to the box, Quiero vaciarla en mi cuarto is correct and more concise.

Why do we say la caja and not una caja here?

Using la caja implies a specific box already known to both the speaker and the listener. Una caja would mean "a box," suggesting it’s not a specific one or hasn’t been mentioned before.
