Learn Italian: Per reclamare l'oggetto, la denuncia va firmata. - To claim the object, the report must be signed.

Using the verb andare (here, va) plus a past participle (firmata) creates a passive structure that expresses necessity. It means the exact same thing as deve essere firmata (must be signed), but this andare structure is heavily used in everyday Italian for rules, instructions, and things that "need to be done."

Why does firmata end in -a?

Because this is a passive construction, the past participle acts like an adjective and must agree with the subject receiving the action. The subject is la denuncia (feminine singular), so the past participle becomes firmata. If the subject were masculine, like il documento, it would be va firmato.

Is denuncia a false friend? It looks like "denunciation".

It often is! While it can translate to "denunciation" in some contexts, in everyday Italian una denuncia is usually a police report or a formal legal complaint. For example, if your wallet is stolen, you go to the police station to file a denuncia.

Why is there a per at the beginning of the sentence?

In Italian, when you want to express "in order to" do something, you use the preposition per followed by the infinitive form of the verb. Here, per reclamare translates to "in order to claim" or simply "to claim."
