Confirmamos el envío.

Confirmamos is the first person plural form of confirmar, so it means we confirm.

In this sentence, Confirmamos el envío means We confirm the shipment / dispatch / sending.

It is made up of:

• confirmar = to confirm
• confirmamos = we confirm

Because it is the nosotros form of a regular -ar verb in the present tense.

For confirmar:

• yo confirmo = I confirm
• tú confirmas = you confirm
• él/ella/usted confirma = he/she/you confirm
• nosotros/nosotras confirmamos = we confirm
• vosotros/vosotras confirmáis = you all confirm
• ellos/ellas/ustedes confirman = they/you all confirm

So -amos tells you the subject is we.

Yes, in some contexts confirmamos can also be the preterite form: we confirmed.

That is because for regular -ar verbs, the nosotros form looks the same in:

• the present: we confirm
• the preterite: we confirmed

So Confirmamos el envío could mean:

• We confirm the shipment
  or
• We confirmed the shipment

Usually the surrounding context makes it clear. In a business message, it will often be understood as a present-time statement: We confirm the shipment.

El envío is a masculine noun that usually means:

• the shipment
• the dispatch
• the sending

In business or logistics contexts, el envío often means the shipment or the package being sent.

Depending on context, it could refer to:

• the act of sending something
• the item that has been sent
• a delivery/shipment

The accent mark shows the correct stress: en-VÍ-o.

Without the accent, envio could be read differently, and it is also a verb form:

• envío = shipment / sending (noun), or I send in some contexts depending on sentence structure
• envio without the written accent is generally not the standard spelling when that stressed í is needed

In el envío, it is clearly the noun: the shipment.

The accent helps show that í is stressed and that the word is pronounced in three syllables:

• en-ví-o

El means the, so el envío means the shipment.

Spanish often uses the definite article when referring to something specific or already understood from context. In a sentence like this, the speaker is probably talking about a particular shipment that both sides know about.

So:

• Confirmamos el envío = We confirm the shipment
• Confirmamos un envío = We confirm a shipment (less specific)

Using el sounds natural if there is a known, specific shipment.

In normal full-sentence Spanish, Confirmamos el envío is the most natural form.

Leaving out the article, as in Confirmamos envío, sounds incomplete or more like:

• a note
• a heading
• very compressed business style

You might see article omission in labels, forms, or short internal messages, but in standard sentence form, el is normally included.

A simple pronunciation guide is:

kon-feer-MAH-mos el en-VEE-oh

A more Spain-oriented pronunciation would be approximately:

com-feer-MA-mos el en-BEE-o

A few useful points:

• c before o sounds like k
• v and b are pronounced very similarly in Spanish
• h is not present here, so nothing silent to worry about
• envío has the stress on ví

The rhythm is:

• con-fir-MA-mos
• el
• en-VÍ-o

It is fairly neutral-formal, and it sounds very natural in:

• business emails
• customer service messages
• logistics or shipping contexts
• official communication

Because the subject we is built into the verb, Spanish does not need to say nosotros:

• Confirmamos el envío = normal
• Nosotros confirmamos el envío = possible, but usually only if you want emphasis

So the sentence is concise and professional.

Yes. It sounds natural, especially in professional or commercial contexts.

For example, it could mean:

• We confirm the shipment
• We confirm that the goods have been sent
• We confirm dispatch

In a real message, you might also see slightly longer versions such as:

• Confirmamos el envío del pedido. = We confirm shipment of the order.
• Le confirmamos el envío. = We confirm the shipment to you.
• Queda confirmado el envío. = The shipment is confirmed.

In Spanish, the verb ending often already tells you the subject.

Here, confirmamos already means we confirm, so we is built into the verb. That is why Spanish often omits subject pronouns.

So:

• Confirmamos el envío = We confirm the shipment
• Nosotros confirmamos el envío = also correct, but more emphatic

Spanish does this much more often than English.

Yes. Depending on context, good translations include:

• We confirm the shipment
• We confirm dispatch
• We confirm the sending
• We confirmed the shipment (if the context is past)

The best English translation depends on the situation:

• in logistics: shipment
• in a general sending context: sending
• if the time reference is past: confirmed

So the Spanish is short, but the exact English wording depends on context.
