Notificamos la clonación de la tarjeta.

Notificamos is the 1st person plural form of notificar — so it means we notify / we inform / we report.

The basic breakdown is:

• notificar = to notify, to inform, to report formally
• notificamos = we notify or we notified, depending on context

Spanish often uses this verb in formal or administrative language, so it sounds more official than everyday avisamos.

Yes. This is a very common learner question because notificamos has the same form in:

• the present indicative: we notify / we are notifying
• the preterite: we notified

So the sentence by itself is ambiguous in terms of tense. Context tells you which one is meant.

In an official notice, it often sounds like a formal present:

• Notificamos la clonación de la tarjeta. = We notify/inform you of the cloning of the card.

But in a narrative context, it could also mean:

• We notified the card cloning.

Because Spanish usually leaves out subject pronouns when the verb already makes the subject clear.

• Notificamos already tells you the subject is we
• so nosotros notificamos is usually unnecessary

Adding nosotros is possible, but it would normally be for emphasis or contrast:

• Nosotros notificamos la clonación de la tarjeta, no el banco.

In neutral Spanish, especially formal written Spanish, the pronoun is normally omitted.

Spanish often uses the definite article with nouns where English would not.

Here, la clonación refers to a specific act or case of cloning:

• la clonación de la tarjeta = the cloning of the card

English might prefer something like card cloning or the cloning of the card, but Spanish naturally uses the article here.

So la is not strange — it is the normal way to package the noun phrase.

De la tarjeta means of the card.

So the structure is:

• la clonación = the cloning
• de la tarjeta = of the card

Together:

• la clonación de la tarjeta = the cloning of the card

In more natural English, you might translate it as card cloning, but Spanish often prefers this noun + de + noun structure.

La tarjeta means the card, so it refers to a specific card already known from the context.

That said, in a real message to a customer in Spain, you would very often see:

• su tarjeta = your card

For example:

• Le notificamos la clonación de su tarjeta.

That sounds more explicit and more natural if the bank is writing directly to the cardholder.

So la tarjeta is grammatical, but it can sound a little less personal or more context-dependent.

Good question. Spanish can use notificar without explicitly saying the recipient.

So:

• Notificamos la clonación de la tarjeta.

focuses on what is being notified: the cloning.

But if you want to say to whom, Spanish often adds an indirect object pronoun:

• Le notificamos la clonación de la tarjeta. = We notify you of the cloning of the card.

Without le, the sentence does not say directly who receives the notification. That person may be understood from the context, or the sentence may be written in a more impersonal/official style.

Yes, especially in banking or fraud contexts.

In Spain, clonación de tarjeta is a normal formal way to refer to illegal copying of a bank card’s data. It is the kind of term you might see in:

• bank alerts
• fraud reports
• police or administrative language

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

• han clonado la tarjeta
• me han copiado la tarjeta
• fraude con la tarjeta

But clonación is perfectly standard and sounds formal/technical.

It is grammatical and understandable, but it sounds quite formal and a little bare.

In Spain, a bank or company might more naturally say something like:

• Le notificamos la clonación de su tarjeta.
• Le informamos de la posible clonación de su tarjeta.
• Hemos detectado una posible clonación de su tarjeta.

Why? Because these versions:

• identify the recipient
• often use su tarjeta
• sometimes sound more natural in customer communication

So your original sentence is correct, but it feels more like a formal heading, an internal note, or a very condensed official statement than everyday customer-facing Spanish.

The structure is:

• Notificamos = verb
• la clonación de la tarjeta = direct object noun phrase

So it is basically:

Verb + object

More literally:

• We notify the cloning of the card

This is a very normal Spanish structure. English often changes it more when translating, but the Spanish grammar itself is straightforward.
