Tenemos que imprimir veinticuatro copias del formulario antes de la reunión.

Spanish often leaves out subject pronouns when they are already clear from the verb ending.

Here, tenemos means we have, so the we is already built into the verb. Because of that, Nosotros tenemos que imprimir... is possible, but it is usually unnecessary unless you want extra emphasis or contrast.

For example:

• Tenemos que imprimir... = normal, neutral
• Nosotros tenemos que imprimir... = emphasizes we

Tener que + infinitive is a very common structure meaning to have to do something.

So:

• tenemos = we have
• que imprimir = to print

Together, tenemos que imprimir means we have to print.

This structure works with all persons:

• tengo que = I have to
• tienes que = you have to
• tiene que = he/she has to
• tenemos que = we have to

After tener que, the next verb stays in the infinitive.

So Spanish says:

• Tenemos que imprimir
  not
• Tenemos que imprimimos or any other conjugated form

This is similar to English:

• We have to print
• not We have to we print

The first verb is conjugated, and the second verb stays in its base form.

Yes, you could. Debemos imprimir veinticuatro copias... is grammatical and natural.

But there is a slight difference in feel:

• tener que often sounds like a practical obligation: we have to
• deber can sound a bit more formal, moral, or like we should / we must, depending on context

In everyday speech, tener que is extremely common and often the most natural choice.

In modern Spanish, the numbers from 21 to 29 are normally written as one word:

• veintiuno
• veintidós
• veintitrés
• veinticuatro

So veinticuatro copias is the standard spelling.

Also, veinticuatro does not change for gender here. Compare that with numbers ending in uno, which do change before nouns:

• veintiún formularios
• veintiuna copias

But veinticuatro stays the same.

Because de + el contracts to del in Spanish.

So:

• de el formulario → del formulario

This contraction is required in normal Spanish.

Compare:

• el libro del profesor = the teacher’s book
• las copias del formulario = the copies of the form

But note that de + la does not contract:

• de la reunión
• not dela reunión

Antes de is used before a noun or before an infinitive.

Here it comes before a noun phrase:

• antes de la reunión = before the meeting

This is the normal pattern:

• antes de + noun
• antes de + infinitive

For example:

• antes de clase
• antes de salir

If what follows is a full clause with a conjugated verb, Spanish uses antes de que instead:

• antes de que empiece la reunión

Because it refers to a specific meeting that both speaker and listener are expected to know about.

Spanish often uses the definite article in places where English does too, and sometimes even where English might be a bit lighter about it. In this sentence, la reunión means the meeting in a specific, known context.

So the phrase is naturally:

• antes de la reunión

If the meeting were not specific, you might say something like antes de una reunión, but that would change the meaning.

The given word order is the most neutral and natural one:

• Tenemos que imprimir veinticuatro copias del formulario antes de la reunión.

But Spanish word order is somewhat flexible. You can move parts of the sentence for emphasis:

• Antes de la reunión, tenemos que imprimir veinticuatro copias del formulario.

That still sounds natural. The original order is just the straightforward, unmarked version.

The form tenemos is the present indicative of tener for nosotros.

So it means we have or, in this structure, we have to.

Here it refers to a present obligation: something that needs to be done now or in the near future, before the meeting.

A few related forms are:

• teníamos que imprimir = we had to print
• tuvimos que imprimir = we had to print
• tendremos que imprimir = we will have to print

The written accent in reunión shows that the stress falls on the last syllable: reu-NIÓN.

The accent mark is needed because words ending in n, s, or a vowel are normally stressed on the second-to-last syllable. Since reunión is stressed on the last syllable instead, it must be written with an accent.

So the accent mark is not optional—it tells you the correct stress.

Yes. The preposition de has several meanings in Spanish, including of, from, and others depending on context.

In this sentence, copias del formulario is understood as copies of the form.

So here del is not really from the form in the physical sense; it is expressing the relationship between the copies and the original document.

That kind of de is very common in Spanish:

• una página del libro = a page of/from the book
• una foto del edificio = a photo of the building
