Perforamos cada pliego con la lezna.

Perforamos is the 1st person plural form (nosotros/nosotras) of perforar.

In this sentence, it is most naturally understood as the present indicative: we perforate / we pierce / we punch.

However, this form can also look identical to the preterite (we perforated). Normally, the wider context tells you which meaning is intended.

• Present: Perforamos cada pliego con la lezna. = We pierce each sheet with the awl.
• Preterite: Ayer perforamos cada pliego... = Yesterday we pierced each sheet...

So the form itself can be ambiguous, but the sentence context usually clears it up.

Because cada is followed by a singular noun in Spanish.

So:

• cada pliego = each sheet
• not cada pliegos

This is the same pattern as:

• cada día = each day
• cada página = each page
• cada libro = each book

Even though the meaning refers to multiple items one by one, the noun stays singular after cada.

Pliego literally means a sheet or folded sheet, but its exact meaning depends on context.

In printing, bookbinding, paper, or administrative contexts, it can mean things like:

• a sheet of paper
• a large sheet
• a printed sheet
• sometimes a signature or folded set of pages in book production

So a learner should know that pliego is not the most general everyday word for a single page. It is a more specific term, often used in technical, printing, paper, or craft contexts.

In Spanish, it is very common to use the definite article with tools, instruments, and body parts where English often uses no article.

So:

• con la lezna = with the awl
• con el cuchillo = with the knife
• con la mano = with the hand

This does not always mean a specific awl already mentioned in English terms. Spanish often simply prefers the article here.

Saying con lezna would sound unnatural in most normal contexts.

A lezna is an awl: a pointed hand tool used to pierce materials such as:

• leather
• paper
• cardboard
• fabric

It is a fairly specific word, and many learners will not meet it early on. It tends to appear in contexts such as:

• bookbinding
• leatherwork
• sewing or craft work
• manual production processes

So this is somewhat specialized vocabulary rather than basic everyday Spanish.

Because cada normally goes directly before the noun, without el/la/los/las.

So you say:

• cada pliego
• cada página
• cada alumno

Not:

• el cada pliego
• la cada página

This is just the normal grammar pattern of cada.

Yes. Spanish word order is flexible, although the original order is the most neutral.

Original:

• Perforamos cada pliego con la lezna.

Possible alternatives:

• Con la lezna, perforamos cada pliego.
• Cada pliego lo perforamos con la lezna.

These alternatives may add emphasis or sound more marked. The original sentence is the most straightforward and natural if you are simply stating the action.

Yes. Con here introduces the instrument or tool used to perform the action.

So:

• perforar algo con una lezna = to pierce something with an awl
• cortar algo con tijeras = to cut something with scissors
• escribir con un bolígrafo = to write with a pen

This is one of the most common uses of con in Spanish.

Because cada pliego is a direct object, and it refers to a thing, not a person.

The so-called personal a is usually used with specific human beings:

• Veo a María.
• Ayudamos a los estudiantes.

But with things, you normally do not use a:

• Perforamos cada pliego.
• Leemos el libro.
• Abrimos la puerta.

So no a is needed here.

It is a correct and useful verb, but it sounds a bit more technical or formal than some everyday alternatives, depending on context.

For example, in less technical speech people might sometimes use verbs like:

• hacer un agujero = to make a hole
• agujerear = to punch / to make holes in
• pinchar = to prick / pierce (depending on context)

But perforar is a very natural choice when talking about actually piercing material, especially in technical, manual, industrial, or craft contexts.

Yes, very likely.

Two words suggest that strongly:

• pliego
• lezna

Together, they make the sentence sound like it comes from a context such as:

• bookbinding
• paper handling
• printing
• leatherwork
• a workshop manual
• craft instructions

So although the grammar is standard, the vocabulary feels specialized rather than casual everyday conversation.
