Learn Italian: Ci fidiamo perché siamo fedeli. - We trust each other because we are faithful.

The verb is fidarsi (to trust). When you use plural reflexive pronouns like ci (us/ourselves), vi (you all/yourselves), or si (them/themselves), they can also act as reciprocal pronouns meaning "each other." So ci fidiamo translates to "we trust each other."

Could ci fidiamo also mean "we trust ourselves"?

Yes, structurally it can mean both. In Italian, you rely on the context to know if a plural reflexive verb means doing the action to "ourselves" or to "each other." Here, the second half of the sentence makes it clear it is about mutual trust. If you ever need to be extra clear, you can add a phrase like l'un l'altro (one another).

Are the words fidiamo and fedeli related?

Yes! They both come from the same root word for faith and trust. Fidarsi is the verb "to trust" and fedele is the adjective for "faithful" or "loyal." Spotting these word families is a great way to grow your vocabulary.

Why does fedeli end in -i instead of -o or -a?

The singular form of this adjective is fedele. Adjectives that end in -e in the singular do not have separate masculine and feminine forms, and they always change to -i in the plural. Since siamo (we are) is plural, fedele becomes fedeli.
