El remitente escribe la dirección postal.

Remitente means sender—the person who sends a letter or package.

In everyday Spanish, it is very common in the context of:

• mail
• shipping
• forms
• packages
• envelopes

For example, on a package you may see:

• Remitente = sender
• Destinatario = recipient

In casual speech, people might also say something like la persona que lo envía, but remitente is the standard single-word term.

Spanish nouns have grammatical gender, so their articles must match:

• el remitente → masculine singular
• la dirección → feminine singular

A few useful notes:

• Dirección is feminine because nouns ending in -ción are almost always feminine.
• Remitente ends in -e, so its gender is not obvious from the ending alone. In this sentence, it appears as el remitente, so it is treated as masculine here.

In real usage, remitente can refer to a man or a woman, but the article may change depending on the person:

• el remitente
• la remitente

Escribe is the third-person singular present tense of escribir (to write).

Conjugation of escribir in the present:

• yo escribo
• tú escribes
• él/ella/usted escribe
• nosotros/nosotras escribimos
• ellos/ellas/ustedes escriben

Because el remitente is a third-person singular subject (the sender), the sentence uses escribe.

This is the most neutral and standard Spanish word order:

Subject + verb + direct object

• El remitente = subject
• escribe = verb
• la dirección postal = direct object

This order is very similar to English:

• The sender writes the postal address.

Spanish can sometimes change word order for emphasis, but this version is the most straightforward and natural for a learner.

Dirección by itself can mean several things, depending on context:

• address
• direction
• management/leadership

Because it can have more than one meaning, adding postal makes it specific:

• dirección postal = mailing address / postal address

So in this sentence, postal clarifies that we are talking about an address used for mail, not a direction like turn left, and not management.

In Spanish, descriptive adjectives usually come after the noun.

So:

• dirección postal not
• postal dirección

This is one of the most common differences from English, where adjectives usually come before nouns:

• postal address

So the pattern here is very normal Spanish:

• noun + adjective

Dirección has a written accent because the stress falls on the last syllable: -ción.

Without getting too technical, Spanish accent marks often show where the word is stressed when it does not follow the most basic stress patterns.

So:

• dirección → stress on ción

The accent mark is important in correct spelling.

A simple approximation for an English speaker:

• remitente ≈ reh-mee-TEN-teh
• dirección ≈ dee-rehk-SYON

A few pronunciation tips for Latin America:

• r in remitente is a light tap
• e and i are pure vowel sounds, not diphthongs like in English
• ción sounds like syon in most of Latin America

Also:

• escribe ≈ ehs-KREE-beh
• postal ≈ poh-STAHL

Sometimes, yes—but they are not always exactly the same.

• dirección postal = mailing address
• domicilio = address/home address/residence, depending on context

Domicilio often refers more to someone's residence or legal address, while dirección postal is specifically about where mail is sent.

So if you are talking about writing the address on mail, dirección postal is the clearest choice.

Yes, escribir la dirección is completely natural and standard.

Other possible verbs depend on the situation:

• anotar la dirección = write down the address
• poner la dirección = put/write the address
• llenar la dirección = fill in the address

But in a simple sentence like this, escribe is a very normal choice.

Yes, in this sentence la is natural and expected because la dirección postal is the direct object and refers to a specific noun phrase.

Spanish often uses articles more frequently than English does.

So:

• El remitente escribe la dirección postal.

English might sometimes say writes the postal address or just writes the address, and Spanish likewise normally keeps the article here.

You could say:

• La remitente escribe la dirección postal.

The rest of the sentence stays the same because:

• escribe still matches a third-person singular subject
• la dirección postal is unchanged

Only the article for remitente changes:

• el remitente
• la remitente

The infinitive is escribir (to write).

Yes, it is a regular -ir verb in the present tense.

Its present-tense endings are regular:

• yo escribo
• tú escribes
• él/ella/usted escribe
• nosotros/nosotras escribimos
• ellos/ellas/ustedes escriben

That makes it a useful verb to learn early, because it follows a predictable pattern.
