Preste atenção

You use it just like 'pay attention' in English. You can use it at the start of a sentence. For example: Preste atenção no que eu digo. You can also use it as a standalone command. If someone is daydreaming, just say the phrase. It works with the preposition em (which becomes no or na). You 'lend attention' *in* something, not *to* something.

Use it when you have important news. Use it in a classroom or a meeting. It is perfect when giving directions to a lost tourist. If you are showing a friend a cool part of a movie, say it then. It is very common when someone is distracted by their phone. It helps reset the conversation focus immediately.

Avoid using it with your boss unless they are literally walking into traffic. It can sound a bit like a teacher talking to a child. If you are in a very formal ceremony, it might be too blunt. Don't use it if you want to be subtle. In those cases, try com licença (excuse me) instead. It is a command, so use it with people you know.

Portuguese speakers are generally very expressive and talkative. Sometimes, three people talk at once! Preste atenção is the verbal 'reset button' for these moments. In Brazil, people might shorten it to just presta atenção. It reflects a culture that values active listening and engagement. If someone says this to you, they really want to connect.

You will often hear Presta atenção in casual speech. The 'e' at the end of preste changes to 'a' in informal Brazilian Portuguese. You might also hear Olha só (Look here) as a synonym. Another common one is Foca aqui (Focus here). If someone is being very serious, they might say Preste muita atenção.
