Revisamos la escalada en polea.

Revisamos is the first person plural form of revisar, so it means we review, we check, or we inspect.

The subject we is not written because Spanish often leaves subject pronouns out when the verb already shows who is doing the action.

In Spanish, the nosotros form of many -ar verbs looks the same in the present and the preterite.

So revisamos can mean either:

• we review / we are reviewing
• we reviewed

Only the context tells you which one is meant.

For example:

• Hoy revisamos la escalada en polea. = Today we review/check pulley climbing
• Ayer revisamos la escalada en polea. = Yesterday we reviewed/checked pulley climbing

Spanish often uses the definite article more than English does.

Here, la escalada refers to the climbing activity/technique/topic being reviewed. In Spanish, it is very normal to use el / la / los / las with nouns for activities, especially when talking about them in a general or specific training/technical context.

So la escalada sounds natural, even where English might sometimes just say climbing.

Escalada is a noun, meaning climbing or climbing activity.

• escalar = to climb → infinitive verb
• escalada = climb / climbing → noun

In this sentence, after revisamos, you need a thing that is being reviewed, so the noun escalada fits better than the infinitive escalar.

En polea is a prepositional phrase describing the type or setup of the climbing.

Literally, polea means pulley, so escalada en polea refers to a kind of climbing done with a pulley system or on pulley-assisted equipment, depending on the context.

The exact technical meaning can vary by field, but grammatically en polea is modifying la escalada.

Both en and con can be possible in Spanish, but they do different jobs.

• con polea = with a pulley → focuses on the tool used
• en polea = in/on a pulley setup/system → focuses more on the type of arrangement or mode

So en polea sounds more like a set expression describing the kind of climbing, not just the instrument.

Yes, polea is feminine: la polea.

You usually learn the gender along with the noun. The ending -a often suggests feminine, and in this case that is correct.

So you would say:

• la polea
• una polea

The basic structure is:

• Revisamos = verb
• la escalada en polea = direct object

So the sentence is:

Verb + object

Spanish allows flexibility, but this is a very normal order. It is especially common when the subject nosotros is omitted.

If you included the subject, it would be:

Nosotros revisamos la escalada en polea.

But usually nosotros is unnecessary unless you want emphasis or contrast.

Because la escalada is a thing, not a person.

Spanish uses the personal a before a specific human direct object, for example:

• Vemos a la profesora.

But here:

• Revisamos la escalada en polea.

There is no personal a because la escalada is an activity/topic, not a person.

A simple pronunciation guide in Spain Spanish would be:

reh-bee-SAH-mos la es-kah-LAH-dha en po-LEH-ah

A few useful points:

• revisamos has the stress on sa
• escalada has the stress on la
• polea has the stress on le
• In much of Spain, d between vowels can sound softer, so escalada may sound a bit like escalaa in fast speech

Yes, if the context is technical, educational, or sport-related, it can sound natural.

It sounds like something you might hear in:

• a training session
• a lesson
• a safety review
• a technical explanation

Without context, it sounds a bit specialized rather than everyday casual conversation, but grammatically it is fine.
