Learn Portuguese (Portugal): Vamos à praia de metro. - We are going to the beach by subway.

In Portuguese, the verb ending usually tells you exactly who is doing the action. Since vamos is the "we" form of the irregular verb ir (to go), it already means "we go" or "we are going". It is completely normal and very common to drop the subject pronoun nós (we).

What does the accent mark on à mean?

That accent marks a contraction. The verb ir (to go) requires the preposition a (to) for destinations. The word praia (beach) is feminine, so it takes the feminine word for "the", which is also a. Instead of saying a a praia, the two identical letters merge into à (to the).

Why do we use the word de before metro?

While English uses the word "by" for modes of transportation (by subway, by bus), Portuguese uses the preposition de (which usually means "of" or "from"). To say you are traveling by a certain vehicle, you will use phrases like de metro, de autocarro (by bus), or de carro (by car).

Can vamos also mean "let's go"?

Yes! Vamos can translate to "we are going", "we go", or even "let's go". You have to rely on the context to know which one is meant. Here, it is simply stating the fact that we are going to the beach.
