Por favor, diga.

Use this whenever you need someone to tell you something. Imagine you're lost in Lisbon and need directions. You'd approach someone and say, Por favor, diga-me o caminho para a estação. (Please tell me the way to the station). Or maybe you're watching a Portuguese movie and missed a line. You could text your friend, O que é que ele disse? Por favor, diga. (What did he say? Please tell me.). It works for simple facts or more complex explanations.

This phrase strikes a lovely balance. It's polite enough for most situations but not so stiff that it sounds like you're addressing royalty. It’s perfect for everyday interactions. You wouldn't use it in a super formal business negotiation, but it’s great for asking your colleague for a file or telling a delivery driver where to leave your pizza. It’s like wearing smart casual – always appropriate!

• Asking for the time: Por favor, diga as horas.
• In a shop: Onde fica a secção de pão? Por favor, diga.
• On public transport: Este autocarro vai para o centro? Por favor, diga.
• Asking for a recipe step: Como se faz o molho? Por favor, diga.
• Clarifying instructions: Não percebi a última parte. Por favor, diga de novo.

Use it when you need information from someone. It's ideal for asking for directions, explanations, or any kind of detail. If you’re trying to understand a new concept, asking for clarification is key. This phrase is your friendly tool for unlocking that knowledge. Think of it as opening a door to understanding. It's also great when you want someone to repeat something they said.

Avoid this if you're in a highly formal setting where a more elaborate phrase is expected, like a legal deposition. Also, don't use it if you're ordering someone around aggressively – it’s meant to be polite! If you're just making small talk, like commenting on the weather, a simple Está um dia bonito, não está? (It's a nice day, isn't it?) is better. It's not for casual gossip either; it's for seeking specific information.

A common slip-up is forgetting the por favor (please). It makes the request sound abrupt. Another mistake is using it when a simpler question works, like just asking Que horas são? (What time is it?) instead of Por favor, diga as horas. It's like showing up to a casual coffee date in a tuxedo – a bit much!

In Brazil, you might hear Por favor, me diz. which is a bit more informal and uses the verb dizer (to say/tell) conjugated for tu but used with você. In Portugal, Por favor, diga-me is very common, adding the pronoun me (me) for clarity. Sometimes people just say Diga? with a rising intonation, implying 'Tell me?' – this is very casual.
