Vemos a lua à noite.

In Portuguese, the subject pronoun is often left out when it is clear from the verb form.

Vemos means we see, so nós is not necessary:

• Vemos a lua à noite. = We see the moon at night.
• Nós vemos a lua à noite. = same meaning, but nós is more explicit or emphatic.

This is very common in Portuguese.

Vemos is the present tense form of the verb ver (to see) for nós (we).

So:

• eu vejo = I see
• você/ele/ela vê = you/he/she sees
• nós vemos = we see
• vocês/eles/elas veem = you/they see

In this sentence, vemos means we see.

Portuguese often uses the definite article more than English does.

So:

• a lua = the moon
• lua = moon in a more general or indefinite sense

In this sentence, a lua is natural because you are talking about the specific moon we all know.

Here, the first a in a lua is the feminine singular definite article, meaning the.

It matches lua, which is a feminine noun:

• o livro = the book
• a casa = the house
• a lua = the moon

This is different from the preposition a meaning to/at, although they look the same in writing when not contracted.

You usually learn the gender of a noun together with its article:

• a lua
• not o lua

There is not always a logical reason from an English perspective; grammatical gender is part of the noun in Portuguese. Over time, you memorize nouns with their articles.

A useful habit is to learn new nouns as a unit:

• a lua
• o sol
• a noite

À noite means at night.

It is a very common time expression in Portuguese:

• de manhã = in the morning
• à tarde = in the afternoon
• à noite = at night / in the evening

Depending on context, à noite can cover both in the evening and at night.

Because it is a contraction of:

• the preposition a
• plus the feminine singular article a

So:

• a + a = à

In à noite, the underlying idea is something like at the night-time period, which Portuguese expresses with this contraction.

The grave accent (`) is not the normal accent mark used for stress; here it shows crasis, the merger of two a sounds.

Yes, in this sentence, a noite would be wrong.

You need à noite because the expression requires the preposition + article contraction:

• correct: à noite
• incorrect here: a noite

But a noite can exist in other contexts, where it simply means the night:

• A noite está linda. = The night is beautiful.

So the accent changes the function:

• a noite = the night
• à noite = at night

This sentence follows a very common Portuguese order:

Verb + object + time expression

• Vemos = we see
• a lua = the moon
• à noite = at night

This is natural and straightforward in Portuguese.

You could also say:

• À noite, vemos a lua.

That puts more focus on at night, but the meaning stays the same.

In Brazilian Portuguese, vemos is usually pronounced approximately like VEH-mus.

A rough guide:

• ve- like veh
• -mos with an unstressed o that often sounds closer to u in Brazilian speech

So it often sounds close to VEH-mus.

Lua is usually pronounced roughly like LOO-ah in Brazilian Portuguese.

It has two vowel sounds:

• lu = loo
• a = ah

So: LOO-ah

Yes, absolutely.

Nós vemos a lua à noite is grammatically correct and means the same thing.

The version without nós is simply more natural in many everyday situations because Portuguese often drops subject pronouns when the verb already makes the subject clear.

In the present tense, Portuguese can often express either:

• a general/habitual fact, or
• something happening now

So Vemos a lua à noite is most naturally understood as a general statement:

• We see the moon at night

If you wanted to make right now clearer, context would usually help, or you could say something more specific.

Yes, sometimes.

In Brazilian Portuguese, à noite can cover the period from evening into night. English often separates in the evening and at night, but Portuguese commonly uses à noite for both, depending on context.

So the exact English translation can vary slightly:

• at night
• in the evening

Yes. Ver is an irregular verb, so some of its forms do not follow the most basic regular pattern.

For example:

• eu vejo
• nós vemos
• ele vê

So it is a good verb to memorize carefully because it is common and useful.
