El perito viene mañana.

Perito usually means an expert in a technical or legal sense, not just someone who is generally skilled.

Depending on context, it can mean:

• an expert witness
• an appraiser
• a forensic specialist
• a surveyor or other certified expert

So the exact English word can change depending on the situation.

El means the, and here it shows that we are talking about a specific expert.

So el perito = the expert / the appraiser / the specialist

This is normal because el perito is the subject of the sentence.

A useful contrast:

• Es perito. = He is an expert.
• El perito viene mañana. = The expert is coming tomorrow.

With professions after ser, Spanish often drops the article, but when the noun is the subject and refers to a specific person, the article is usually used.

Viene is the 3rd person singular present tense of venir (to come).

Conjugation:

• yo vengo
• tú vienes
• él/ella/usted viene
• nosotros venimos
• vosotros venís
• ellos/ellas/ustedes vienen

Because el perito is singular, the verb is viene.

Spanish often uses the present tense to talk about a planned, expected, or scheduled future action, especially when there is a clear time expression like mañana.

So El perito viene mañana is very natural Spanish.

It works like English sentences such as:

• The expert comes tomorrow
• The expert is coming tomorrow

In everyday Spanish, this is extremely common.

Yes. All three are possible, but they can feel slightly different:

• El perito viene mañana.
  Very natural for something arranged or expected.

• El perito va a venir mañana.
  Also very common; can sound a bit more explicit about a future plan.

• El perito vendrá mañana.
  Simple future; sometimes sounds a little more formal, predictive, or less immediate in everyday speech.

In conversation, the present tense and ir a + infinitive are often more common than the simple future.

Here it means tomorrow.

Mañana can mean two things:

• tomorrow
• morning

Context tells you which one is meant.

Examples:

• Viene mañana. = He/She is coming tomorrow.
• por la mañana = in the morning
• la mañana = the morning

In El perito viene mañana, the natural meaning is tomorrow.

Because Spanish usually doesn’t need subject pronouns when the subject is already clear.

Here, the subject is explicitly stated as el perito, so adding él would be unnecessary.

Natural:

• El perito viene mañana.

Not natural as a normal sentence:

• Él el perito viene mañana.

If you wanted to use él, you would normally do it only when the noun subject is not present:

• Él viene mañana. = He is coming tomorrow.

Spanish is a language that often drops pronouns because the verb form already helps identify the person.

Yes, venir is the right verb if the movement is understood as toward the speaker, toward the place being discussed, or toward the relevant destination.

• venir = to come
• ir = to go

So:

• El perito viene mañana. = The expert is coming tomorrow.
• El perito va mañana. = The expert goes/is going tomorrow.

Spanish chooses between venir and ir based on point of view, just like English.

Yes, venir is irregular.

It has a stem change:

• e → ie in some present-tense forms

So:

• venir
• yo vengo
• tú vienes
• él/ella/usted viene

But:

• nosotros venimos
• vosotros venís

So viene is irregular because it comes from that stem-changing pattern.

Yes. Spanish word order is more flexible than English.

You could also say:

• Mañana viene el perito.

This still means the same thing, but it puts more emphasis on mañana.

Very roughly:

• El perito viene mañana. = neutral statement
• Mañana viene el perito. = emphasis on tomorrow

Both are correct.

A simple approximation is:

el peh-REE-toh BYEH-neh ma-NYA-na

A few pronunciation notes:

• v in Spanish is pronounced much like a soft b
• ie in viene sounds like byeh
• ñ in mañana sounds like ny in canyon
• stress:
  • peRIto
  • VIEne
  • maÑAna

So mañana is not pronounced like manana in English spelling; the ñ matters.

Because it follows the normal Spanish stress rules, so no accent mark is needed.

Mañana ends in a vowel, and words ending in a vowel, n, or s are normally stressed on the second-to-last syllable.

So:

• ma-ÑA-na

That stress is regular, so no written accent is required.

The mark you do see is ñ, but that is not an accent mark. It is a separate letter of the alphabet.

Yes, depending on context, English might translate it as:

• The expert is coming tomorrow
• The expert arrives tomorrow

Spanish venir mainly means to come, but in natural translation English sometimes uses arrive if that sounds better in context.

So the core idea is that the expert will come / show up tomorrow.
