El príncipe vuelve mañana.

Vuelve is the third-person singular present indicative form of volver.

That means it can go with:

• él = he
• ella = she
• usted = you (formal)

In this sentence, the subject is el príncipe, so vuelve means he returns / he comes back.

Spanish often uses the present tense to talk about the near future, especially when a time expression makes the future clear.

So El príncipe vuelve mañana is a very natural way to say:

• The prince returns tomorrow
• The prince is coming back tomorrow

Because mañana already tells us when, Spanish does not need a future form here.

Yes. El príncipe volverá mañana is also correct.

The difference is mainly one of style and nuance:

• El príncipe vuelve mañana = very natural, often used for plans, schedules, or expected events
• El príncipe volverá mañana = simple future, a bit more formal or more clearly future-oriented

In everyday speech, the present tense with a future time word is extremely common.

Because príncipe is a common noun, not a person’s name.

In Spanish, when you mean the prince in a general way, you normally need the definite article:

• el príncipe

You would not normally say just príncipe vuelve mañana in ordinary speech.

Spanish uses articles more regularly than English in many cases, and here el is simply the normal, required form.

Yes, they are very close in meaning.

Volver commonly means:

• to return
• to come back

So El príncipe vuelve mañana means the prince is coming back / returning tomorrow.

Regresar can often be used in the same way:

• El príncipe regresa mañana

In Spain, volver is extremely common and very natural in everyday speech.

Yes, mañana can mean either:

• tomorrow
• morning

But in this sentence, it clearly means tomorrow.

Why?

• There is no article before it
• The sentence is talking about when the prince returns

Compare:

• vuelve mañana = he comes back tomorrow
• vuelve por la mañana = he comes back in the morning
• la mañana = the morning

So context and structure tell you which meaning is intended.

Because that is a very normal place for a time expression in Spanish.

El príncipe vuelve mañana sounds neutral and natural.

Spanish word order is flexible, so you could also say:

• Mañana vuelve el príncipe

That version puts more emphasis on mañana.

So the original order is just the most straightforward, neutral way to say it.

Yes, if the context already makes it clear who you are talking about.

Spanish often leaves out subjects when they are already known:

• Vuelve mañana = He/She is coming back tomorrow or You are coming back tomorrow (formal), depending on context

But in El príncipe vuelve mañana, the speaker explicitly says who is returning, so the subject is included.

Because the stress falls on the third-to-last syllable:

prín-ci-pe

Words stressed on the third-to-last syllable are called esdrújulas, and in Spanish they always take a written accent.

So the accent in príncipe is required.

In standard Peninsular Spanish, a rough pronunciation would be:

el PRIN-thee-peh BWEL-beh ma-NYA-na

A few useful details:

• príncipe: the c before i is usually pronounced like th in thin in most of Spain
• vuelve: the v sounds very similar to Spanish b
• mañana: ñ sounds like the ny in canyon
• The stress is on:
  • PRÍNcipe
  • VUELve
  • maÑAna

So the rhythm is: El PRÍNcipe VUELve maÑAna

Yes, absolutely.

Ir a + infinitive is another very common way to talk about the future:

• El príncipe va a volver mañana

This is similar to The prince is going to return tomorrow.

So you have three natural options:

• El príncipe vuelve mañana
• El príncipe va a volver mañana
• El príncipe volverá mañana

All are correct, but the first one is especially common in everyday Spanish when a future time word is already present.
