Revisamos el manual de instrucciones y el reglamento.

Revisamos can mean either we review / we are reviewing or we reviewed, depending on context.

This is because it is the 1st person plural form of both:

• the present tense: revisamos = we review
• the preterite: we reviewed

So the sentence could mean either:

• We review the instruction manual and the regulations
• We reviewed the instruction manual and the regulations

Usually, the surrounding context tells you which meaning is intended.

In Spanish, it is very normal to repeat the definite article before each noun:

• el manual
• el reglamento

So el manual de instrucciones y el reglamento sounds natural and correct.

In English, we often say the instruction manual and the regulations, using the once for the whole phrase. Spanish often prefers repeating the article when two separate nouns are being linked.

You may sometimes see the article omitted before the second noun in other contexts, but here repeating el is the most standard and natural choice.

Spanish often uses de + noun to show what something is for, about, or related to.

So:

• manual de instrucciones = instruction manual
• literally: manual of instructions

This de structure is extremely common in Spanish. A few similar examples are:

• libro de texto = textbook
• caja de herramientas = toolbox
• gafas de sol = sunglasses

Using para here would sound unnatural. Manual de instrucciones is the fixed, standard expression.

It is plural because the idea is a manual containing instructions—that is, multiple instructions, directions, or steps.

So:

• manual de instrucciones = instruction manual
• literally: manual of instructions

This is just the usual expression in Spanish. Even though English often uses a singular noun as an adjective (instruction manual), Spanish normally keeps instrucciones as a plural noun after de.

They refer to different kinds of texts:

• manual = a manual, guide, handbook
• reglamento = a set of rules, regulations, or official rules

So:

• el manual de instrucciones is something that explains how to use or do something
• el reglamento is a document containing rules that must be followed

A reglamento is usually more formal and rule-based than a manual.

The personal a is used before specific human direct objects, and sometimes pets or personified beings.

Here, the direct objects are:

• el manual de instrucciones
• el reglamento

These are things, not people, so there is no personal a.

That is why the sentence is simply:

• Revisamos el manual de instrucciones y el reglamento.

and not anything with a before those nouns.

The verb is revisamos = we review / we reviewed.

Ask yourself: What did we review?

Answer:

• el manual de instrucciones y el reglamento

That whole phrase is the direct object of the verb.

So the sentence structure is:

• Revisamos = verb
• el manual de instrucciones y el reglamento = direct object

Spanish word order here is straightforward and matches a common English pattern:

• We reviewed the instruction manual and the regulations.

Yes. Spanish very often omits subject pronouns when they are not needed.

So instead of saying:

• Nosotros revisamos el manual de instrucciones y el reglamento

Spanish usually just says:

• Revisamos el manual de instrucciones y el reglamento

The ending -amos already tells you the subject is we.

This is one of the biggest differences from English, where the subject usually has to be stated.

Not exactly. These verbs can overlap, but they are not always interchangeable.

• revisar = to review, check, inspect, go over
• repasar = to go over again, revise, review for study
• comprobar = to verify, check, confirm

In this sentence, revisamos suggests we checked/reviewed/looked over the manual and the regulations.

If you were studying for an exam, repasar might be more natural for reviewing notes.
If you were confirming whether something is correct, comprobar might fit better.

Yes, depending on context, reglamento can be translated in different ways:

• regulations
• rules
• rulebook
• official policy or set of rules

The best translation depends on the situation.

For example:

• in a school, club, or competition, reglamento may mean rules
• in an official or legal context, it may be closer to regulations

So el reglamento is often a formal document that lays out rules.

In standard Spain Spanish, revisamos is pronounced approximately:

• reh-bee-SAH-mos

A bit more precisely:

• re as in a short reh
• vi with a clear b/v sound, which in Spanish is usually much softer than English b
• stress on sa: re-vi-SA-mos

So the stress is on the second-to-last syllable, which is normal for a word ending in -s.

No, not here.

Spanish normally uses y for and:

• el manual de instrucciones y el reglamento

You only change y to e before words that begin with an i sound, such as:

• padre e hijo
• España e Italia

But reglamento does not begin with an i sound, so y is correct.

Yes, it sounds completely natural in Spain.

It is a clear, standard sentence with normal vocabulary and structure:

• Revisamos = we review / reviewed
• el manual de instrucciones = the instruction manual
• y el reglamento = and the regulations / the rules

A speaker in Spain would understand it immediately, and nothing in it sounds unusual or unnatural.
