Esperar vs. aguardar
While both esperar and aguardar translate to to wait in English, they are not always interchangeable. The primary difference lies in their level of formality, context, and a secondary meaning exclusive to esperar.
Esperar
A1Esperar is the most common and versatile word for to wait. It is used in all kinds of everyday, informal situations. Crucially, esperar also has a second important meaning: to hope.
Vou esperar por você na paragem do autocarro.
(I will wait for you at the bus stop.)
Espero que estejas bem.
(I hope you are well.)
Tens de esperar pela tua vez na fila.
(You have to wait for your turn in the line.)

(He waited two hours for the train.)

(Don't make me wait too long!)
Espero receber boas notícias em breve.
(I hope to receive good news soon.)
Estamos a esperar que a chuva pare para podermos sair.
(We are waiting for the rain to stop so we can go out.)
Aguardar
B1Aguardar also means to wait, but it is more formal and is often used in official, commercial, or professional contexts. It implies a more patient or formal act of awaiting something or someone and does not mean to hope.
Por favor, aguarde na linha enquanto transferimos a sua chamada.

Summary
In short, use esperar for general, everyday waiting and also for expressing hope. Use aguardar for more formal, official, or commercial situations where you are awaiting something. While aguardar can sometimes be used in place of esperar to sound more polite or formal, esperar cannot replace aguardar in contexts that demand high formality, and aguardar can never be used to mean to hope.
