Controfirmiamo il patto di riservatezza.

Controfirmiamo is the 1st person plural present indicative of controfirmare.

• controfirmare = to countersign
• controfirmiamo = we countersign / we are countersigning

A useful thing to remember: Italian present tense often covers both the English simple present and present progressive, so the exact English translation depends on context.

Because Italian usually drops subject pronouns when the verb ending already makes the subject clear.

In controfirmiamo, the ending -iamo tells you the subject is we.

So:

• Controfirmiamo il patto di riservatezza. = normal, natural Italian
• Noi controfirmiamo il patto di riservatezza. = adds emphasis, as in we countersign it

Italian uses noi only when it is needed for emphasis, contrast, or clarity.

They look similar, but they are different verbs.

• controfirmiamo comes from controfirmare = to countersign
• confermiamo comes from confermare = to confirm

So controfirmiamo does not mean we confirm. It specifically refers to adding a signature as a countersignature.

This is an easy false friend for learners because English confirm and Italian confermare are close, but controfirmare is something else.

Yes, it can, depending on context and tone.

In Italian, the 1st person plural imperative has the same form as the 1st person plural present indicative:

• Controfirmiamo il documento.
  can mean We countersign the document
  or Let’s countersign the document

With a neutral written sentence like the one you were given, it is usually read as a statement. But in speech, intonation can make it sound like a suggestion or proposal.

Il is the definite article meaning the.

So:

• il patto = the agreement / the pact
• un patto = an agreement / a pact

Italian uses articles more often than English, especially before nouns that refer to something specific or already known in context. If the confidentiality agreement is a specific document both speakers know about, il patto is natural.

This is a very common Italian structure:

noun + di + noun

Here:

• patto = agreement / pact
• riservatezza = confidentiality

So patto di riservatezza literally means something like agreement of confidentiality.

In English, we often turn this into an adjective-based phrase, such as confidentiality agreement, but Italian often prefers di + noun structures.

Similar patterns:

• permesso di soggiorno = residence permit
• contratto di lavoro = work contract
• camera da letto = bedroom

Riservatezza is an abstract noun meaning confidentiality, privacy, or discretion, depending on context.

It is related to the adjective riservato:

• una persona riservata = a reserved/private person
• informazioni riservate = confidential information
• riservatezza = confidentiality / discretion / privacy

In this sentence, the legal/business sense is clearly confidentiality.

Yes, it is understandable and grammatically correct, but in many business or legal contexts, a more common phrase would be:

• accordo di riservatezza
• sometimes accordo di non divulgazione

So a native speaker might more often say accordo than patto in formal document language.

Very roughly:

• patto can sound a bit more like pact
• accordo is often the more standard word for agreement

That said, patto di riservatezza is still perfectly understandable.

Only if you mean we sign, not we countersign.

• firmiamo = we sign
• controfirmiamo = we countersign

Controfirmare implies an additional signature, often after another person has already signed, or a signature added to validate or authorize the document.

So the choice depends on the exact situation.

A helpful approximate pronunciation is:

kon-tro-feer-MYAH-mo

A few tips:

• the stress falls on -mia-
• r should be tapped or rolled, not pronounced like an English r
• Italian vowels are usually clear and pure, without much gliding

So try to keep each vowel clean: con-tro-fir-mia-mo.
