Learn Croatian: Ne idemo pješice, vozimo se u autu. - We are not going on foot, we are riding in the car.

In English, you can just say 'go by car', but Croatian makes a clearer distinction. While ići (to go) is used for walking (idemo pješice) or general movement, you use voziti se to specifically say you are traveling in a vehicle.

What does the se do in vozimo se? Can I just say vozimo u autu?

The word se makes this verb about your own movement as a passenger or driver. The base verb voziti means 'to drive' something. If you drop the se, you would need a direct object, like vozimo auto (we are driving the car). vozimo se simply means 'we are riding'.

Why does auto become autu here?

You are using the preposition u (in) to describe where you currently are. This requires the Locative case, which adds the ending -u to masculine nouns like auto. If you used the Accusative case (u auto), it would imply motion, meaning you are getting into the car, rather than riding inside it.

Is pješice a noun in a specific case here?
