Revisamos la periodicidad de la ITV.

Revisamos is the 1st person plural form of revisar: we check / we review.

In this form, Spanish has an ambiguity:

• present tense: we check / we review
• preterite: we checked / we reviewed

So Revisamos la periodicidad de la ITV could mean either:

• We check the ITV schedule/frequency
• We checked the ITV schedule/frequency

Usually, the wider context tells you which one is meant.

All three verbs can be possible in some contexts, but they are not exactly the same:

• revisar = to review, inspect, check over
• comprobar = to verify, confirm, check whether something is correct
• mirar = to look at

In this sentence, revisamos suggests examining or reviewing the required interval/validity schedule, not just glancing at it.

Also, be careful: revisar is not the usual Spanish equivalent of English to revise in the sense of studying again for an exam. In Spanish, revisar usually means to check/review/inspect.

La periodicidad means the periodicity, that is, how often something happens or the interval at which it must be done.

In this context, it refers to how often the ITV has to be done.

A more natural English translation might be:

• the inspection interval
• the required frequency
• how often the ITV is required

So even though periodicity is a direct equivalent, in natural English you might translate it more freely.

Spanish often uses the definite article more than English does.

Here, la periodicidad means the specific periodicity/frequency being discussed. It sounds natural in Spanish because it refers to a known concept in the context.

Compare:

• Revisamos la periodicidad de la ITV.
  = We check the ITV frequency/interval.

Without the article, Revisamos periodicidad..., it would sound incomplete or unnatural.

In Spain, ITV stands for Inspección Técnica de Vehículos, the official roadworthiness inspection for vehicles.

It takes la because the head noun is inspección, which is feminine:

• la Inspección Técnica de Vehículos
• therefore: la ITV

This is very common with abbreviations in Spanish: the article usually matches the gender of the full noun phrase behind the abbreviation.

De here means of and shows a relationship between the two nouns:

• la periodicidad de la ITV = the periodicity/frequency of the ITV

In more natural English, that often becomes:

• the ITV frequency
• the ITV schedule
• how often the ITV is required

Spanish commonly links nouns with de where English may prefer a noun modifier.

In context, yes, the idea in English may be closer to for the ITV:

• la periodicidad de la ITV literally: the periodicity of the ITV
• natural meaning: how often the ITV must be done

So the literal grammar uses de, but the most natural English translation may not always keep of.

This is normal: Spanish and English often structure noun phrases differently.

It is a normal word, but it sounds a bit formal or administrative. In official or technical contexts, it is very common.

In more everyday speech, people might also say things like:

• cada cuánto pasa la ITV
• cada cuánto hay que pasar la ITV
• la frecuencia de la ITV

So periodicidad is perfectly correct, especially in documents, websites, and official explanations.

By itself, it is most naturally a statement:

• We check / We checked the ITV frequency

If you wanted an instruction in Spain Spanish, you would usually use:

• Revisemos la periodicidad de la ITV. = Let’s check the ITV frequency.
• Revisa la periodicidad de la ITV. = Check the ITV frequency. (informal singular)
• Revise la periodicidad de la ITV. = Check the ITV frequency. (formal singular)

So revisamos is not normally the imperative here.

Because revisar takes a direct object directly, without a preposition:

• Revisamos la periodicidad = We check the frequency

After that, de la ITV modifies periodicidad, not the verb:

• [la periodicidad] [de la ITV]

So the structure is:

• revisamos = verb
• la periodicidad de la ITV = direct object

Yes, absolutely. That would also be correct.

The nuance is slight:

• revisamos = we review/check over
• comprobamos = we verify/confirm

If the idea is we look up and confirm how often it is required, comprobamos may even sound especially natural.

Both are good; revisamos is just a bit broader.

Yes. ITV is the standard term in Spain for the vehicle technical inspection.

A learner of Spanish from another country should note that this is very much Spain-specific vocabulary. Other Spanish-speaking countries may use different names for similar inspections.

So if you are learning Spanish from Spain, ITV is a very useful term to know.
