Llegamos pasado mañana.

In Spanish, the present tense is very often used to talk about the future when the event is already planned, expected, or scheduled.

So Llegamos pasado mañana literally uses the present form llegamos, but the time expression pasado mañana makes it clear that it refers to the future.

This is very natural in Spanish, just like in English when we say:

• We arrive the day after tomorrow
• We’re arriving the day after tomorrow

You could also say Llegaremos pasado mañana, and that is correct too. It just sounds a bit more explicitly future-oriented. In everyday speech, the present is extremely common.

It can mean more than one thing, depending on context.

Llegamos can be:

• present tense: we arrive / we are arriving
• preterite: we arrived

This happens because the nosotros form of some -ar verbs is spelled the same in the present and the preterite.

So:

• Llegamos pasado mañana = clearly present used for future, because pasado mañana points to the future
• Llegamos ayer = clearly preterite, because ayer points to the past

The time expression usually removes the ambiguity.

Spanish often leaves out subject pronouns when the verb ending already shows who the subject is.

In llegamos, the ending -amos tells you the subject is we.

So:

• Llegamos pasado mañana = natural
• Nosotros llegamos pasado mañana = also correct, but usually only used for emphasis, contrast, or clarity

For example, you might say Nosotros llegamos pasado mañana, pero ellos llegan hoy to stress the difference.

Pasado mañana is a fixed adverbial expression meaning the day after tomorrow.

It functions as a time expression, answering when?

In the sentence:

• Llegamos = the verb
• pasado mañana = the time phrase

Spanish uses it without a preposition here, just as English can say We arrive tomorrow without on.

Because pasado mañana is a fixed idiomatic expression.

Even though pasado often means past or last, in this expression it does not mean yesterday morning or the past morning. The whole phrase pasado mañana simply means the day after tomorrow.

Compare:

• mañana = tomorrow
• pasado mañana = the day after tomorrow

So it is best learned as one set phrase.

No. In this sentence, no preposition is needed.

Spanish commonly uses time expressions directly after the verb:

• Llego mañana
• Llegamos el lunes
• Salen esta noche
• Volvemos pasado mañana

So Llegamos pasado mañana is perfectly normal.

Yes. Spanish word order is flexible, although some orders sound more neutral than others.

The most neutral order here is:

• Llegamos pasado mañana

But you could also say:

• Pasado mañana llegamos

This version puts more focus on the time expression, as if highlighting the day after tomorrow.

Both are correct; the difference is mainly emphasis and style.

No, because llegar only takes a when you mention the destination.

For example:

• Llegamos a Madrid pasado mañana = We arrive in Madrid the day after tomorrow
• Llegamos a casa pasado mañana = We get home the day after tomorrow

But if you are only saying when you arrive, with no destination, then no a is needed:

• Llegamos pasado mañana

In standard Spain pronunciation, it would sound roughly like:

• llegamos → ye-GA-mos or in some areas a sound closer to lle-GA-mos
• pasado mañana → pa-SA-do ma-NYA-na

A few useful points:

• ll in most of Spain is pronounced like y in yes
• ñ sounds like ny in canyon
• the j sound does not appear here, so there is nothing especially harsh in this sentence
• stress falls on ga in llegamos and on sa and ña in pasado mañana

It may feel clearer to a learner, and it is absolutely correct. But native speakers very often prefer the present tense for planned future events.

So:

• Llegamos pasado mañana = very natural
• Llegaremos pasado mañana = also correct and natural

If you want to sound more conversational, the present-tense version is a very useful pattern to learn.

Yes.

• Llegamos pasado mañana
• Pasado mañana llegamos

Both mean the same thing. The second version simply gives more prominence to pasado mañana.

This is common in Spanish: time expressions can often move around more freely than in English, especially for emphasis.
