Revisamos el permiso de circulación.

Revisamos can mean either:

• we check / we review (present tense)
• we checked / we reviewed (preterite, simple past)

So this form is ambiguous on its own. Spanish often relies on context to tell you which meaning is intended.

For example:

• Ahora revisamos el permiso de circulación. = Now we’re checking the vehicle permit.
• Ayer revisamos el permiso de circulación. = Yesterday we checked the vehicle permit.

This happens with some -ar verbs in the nosotros form.

Because Spanish often drops subject pronouns when the verb ending already shows who is doing the action.

• Revisamos already tells you the subject is we
• So nosotros is usually unnecessary

You could say Nosotros revisamos el permiso de circulación, but it would normally add emphasis, contrast, or clarity.

For example:

• Nosotros revisamos el permiso, no ellos.
  = We checked the permit, not them.

Not usually in the English sense of editing or rewriting something.

In this sentence, revisar means more like:

• to check
• to inspect
• to look over
• to review

This is a common false-friend issue for English speakers.
So Revisamos el permiso de circulación is more naturally understood as We checked/reviewed the vehicle permit, not We revised it.

El means the, while un means a/an.

Using el permiso suggests a specific permit is being referred to — probably one that both speaker and listener already know about, or the relevant one in the situation.

So:

• Revisamos el permiso de circulación. = We checked the vehicle permit.
• Revisamos un permiso de circulación. = We checked a vehicle permit. (one permit, not necessarily a specific known one)

In real contexts like paperwork, inspections, or traffic-related situations, Spanish often uses the definite article because the document is specific.

In Spain, permiso de circulación is a standard term for a vehicle document. It refers to the official document that identifies the vehicle and authorises it for legal circulation/road use.

A very natural English rendering is often something like:

• vehicle registration certificate
• vehicle permit
• registration document

The exact translation can vary depending on the context, but in Spain it is a fixed administrative expression.

Because Spanish very often uses the pattern:

noun + de + noun

to create fixed expressions.

Here:

• permiso = permit
• de circulación = of circulation / for road use / for being driven legally

So permiso de circulación is the normal established term.

While permiso para circular could be understandable in some contexts, it does not sound like the standard name of the document. Permiso de circulación is the idiomatic expression.

The accent mark in circulación shows where the stress falls:

• cir-cu-la-CIÓN

Without the accent mark, Spanish stress rules would suggest a different pronunciation.

Words ending in -n, -s, or a vowel are normally stressed on the second-to-last syllable, unless there is an accent mark.
Because circulación ends in -n but is stressed on the last syllable, it needs the written accent.

A Spain pronunciation would be approximately:

reh-bee-SAH-mos el pehr-MEE-so deh theer-koo-lah-THYON

A few helpful notes:

• r in revisamos is a light tap
• v and b sound very similar in Spanish
• in much of Spain, c before i is pronounced like th in thin, so circulación sounds like thirculación
• the stress is on:
  • re-vi-SA-mos
  • per-MI-so
  • cir-cu-la-CIÓN

Yes. It is the nosotros form of revisar.

Present tense:

• yo reviso
• tú revisas
• él/ella/usted revisa
• nosotros/nosotras revisamos
• vosotros/vosotras revisáis
• ellos/ellas/ustedes revisan

This is a regular -ar verb, so it follows a very common pattern. Learning revisamos helps you recognise many similar forms, such as:

• miramos = we look / we looked
• hablamos = we speak / we spoke
• compramos = we buy / we bought

Again, notice that the nosotros form can be identical in the present and preterite for many regular -ar verbs.
