Learn Croatian: Tražimo kruh u pekarnici. - We are looking for bread in the bakery.

We are talking about a location, so the noun goes into the locative case after the preposition u (in). For feminine nouns that end in -a like pekarnica, you drop the -a and add -i to make the locative form pekarnici.

Where is the word for 'we' in this sentence?

In Croatian, you usually don't need to use subject pronouns like mi (we). The verb ending in tražimo (-mo) already tells you that 'we' are the ones doing the action.

Why doesn't kruh have a special ending if it's the direct object we are looking for?

Direct objects take the accusative case. For masculine nouns that represent non-living things, like kruh (bread), the accusative form looks exactly the same as the basic dictionary form. If we were looking for a living thing, the ending would change!

Is there a missing word for 'are' in 'are looking'?

No, Croatian doesn't have a separate continuous tense like English does. The single verb tražimo translates to both 'we look for' and 'we are looking for' depending on the context.
