El remitente francés envía el paquete.

Remitente means sender: the person who sends something.

In mailing or shipping contexts:

• remitente = sender
• destinatario = recipient / addressee

So in this sentence, El remitente francés is the French sender.

Because both nouns are being used as specific, definite nouns:

• el remitente = the sender
• el paquete = the package

Spanish uses definite articles very often, just like English does in sentences like this.

In Spanish, descriptive adjectives usually come after the noun.

So:

• el remitente francés = the French sender

That is the normal order.

If you put the adjective before the noun, it often sounds literary, marked, or changes the nuance. For a basic neutral sentence, noun + adjective is the standard pattern.

The accent mark in francés shows where the stress goes:

• fran-CÉS

Without the accent, Spanish stress rules would make you expect a different pronunciation.

So the written accent helps show the correct pronunciation and stress.

Envía is the third-person singular present tense form of enviar:

• yo envío
• tú envías
• él/ella/usted envía

The accent mark shows that the í is stressed and pronounced in a separate syllable:

• en-VÍ-a

So envía is pronounced roughly en-VEE-ah, not as one merged syllable at the end.

Envía is in the present indicative.

It can mean:

• sends
• is sending

Spanish present tense often covers both the simple present and the English present progressive, depending on context.

So:

• El remitente francés envía el paquete
  can mean
• The French sender sends the package
  or
• The French sender is sending the package

The subject is El remitente francés.

The verb envía is a third-person singular form, which matches:

• el remitente = the sender

So the structure is:

• El remitente francés = subject
• envía = verb
• el paquete = direct object

In other words: The French sender + sends + the package.

Yes, but it would mean He sends/is sending the package, not The French sender sends the package.

Spanish often omits subject pronouns because the verb ending already shows the person:

• envía already tells you it is he/she/you formal

So when the full noun subject is present:

• El remitente francés envía el paquete

you do not need él.

Because el paquete is a thing, not a person.

Spanish uses the personal a before a specific person who is the direct object, but not usually before things.

Compare:

• Envía el paquete. = He sends the package.
• Ve al destinatario. = He sees the recipient.

So no a is needed before el paquete.

A simple Latin American pronunciation guide would be:

el reh-mee-TEN-te fran-SESS em-BEE-ah el pa-KE-te

A few notes:

• r in remitente is a light tap
• z in most of Latin America sounds like s, so francés sounds like fran-SESS
• v in envía sounds very close to b in Spanish
• envía has the stress on ví

In this sentence, yes: el remitente refers to a male sender.

But remitente is a noun that can often be used for either gender, with the article showing the gender:

• el remitente = the male sender
• la remitente = the female sender

So the noun itself does not change here, but the article can.

You would normally say:

• La remitente francesa envía el paquete.

Changes:

• el → la
• francés → francesa

That is because the adjective must agree with the noun in gender and number.

For a masculine or mixed-gender plural:

• Los remitentes franceses envían el paquete.

For a feminine plural:

• Las remitentes francesas envían el paquete.

Notice the changes:

• remitente → remitentes
• francés → franceses / francesas
• envía → envían

Everything has to agree properly with the plural subject.

Here it is an adjective because it describes remitente:

• el remitente francés = the French sender

But francés can also be a noun in other contexts:

• El francés habla. = The Frenchman is speaking. / The French person is speaking.
• Estudia francés. = He/she studies French.

So the word’s role depends on the sentence.
