Confiamos en la justicia.

Because confiar usually takes the preposition en when you mean to trust in or to have confidence in someone or something.

• confiar en alguien/algo = to trust someone/something
• Confiamos en la justicia = we trust justice / we have confidence in justice

Without en, confiar often changes meaning and can mean to entrust something to someone:

• Le confié mi secreto. = I entrusted my secret to him/her.

So in this sentence, en is the normal and necessary preposition.

Confiamos is the first person plural form of confiar in the present indicative:

• yo confío
• tú confías
• él/ella confía
• nosotros/nosotras confiamos
• vosotros/vosotras confiáis
• ellos/ellas confían

So confiamos means we trust.

One useful extra point: confiamos can also be the preterite form (we trusted), because for regular -ar verbs the nosotros form looks the same in the present and preterite. Normally, context tells you which meaning is intended. In a standalone sentence like this, the present tense is the most natural reading.

Because Spanish often leaves out subject pronouns when they are not needed.

The ending -amos already tells you the subject is we. So Confiamos en la justicia is a complete sentence by itself.

You could add nosotros if you want emphasis or contrast:

• Nosotros confiamos en la justicia, pero ellos no.
  = We trust justice, but they do not.

So omitting nosotros is normal Spanish, not incomplete Spanish.

Spanish often uses the definite article with abstract nouns more than English does.

So where English may say simply justice, Spanish often says la justicia.

Here la justicia can mean:

• justice as an abstract idea
• or the justice system, depending on context

Using la makes the phrase sound natural in Spanish. Leaving it out would usually sound less idiomatic here.

Because justicia is a grammatically feminine noun, so it takes la:

• la justicia

Many nouns ending in -a are feminine, and justicia follows that common pattern.

Remember that grammatical gender does not always match biological gender. Here it is just a property of the noun, and it affects the article and any adjectives used with it:

• la justicia es importante
• la justicia española

It can mean slightly different things depending on context:

1. Justice as a general principle or value

   • fairness, what is morally right

2. The justice system

   • courts, judges, the legal system

In Confiamos en la justicia, both readings are possible unless the wider context makes one clearer. A learner should be aware that Spanish often allows this kind of overlap.

In standard Spain Spanish, a rough guide is:

kon-FYAH-mos en la khoos-TEE-thya

A few key points:

• confiamos is pronounced in three syllables: con-fia-mos
• The stress is on fia: con-FIA-mos
• The j in justicia is the strong Spanish j sound, made in the back of the throat
• In most of Spain, c before i is pronounced like th in thin

So justicia sounds roughly like:

khoos-TEE-thya

If you hear Latin American Spanish, that c is usually pronounced like s instead.

Yes, but it does not mean exactly the same thing.

• confiar en = to trust in / to have confidence in
• creer en = to believe in

So:

• Confiamos en la justicia suggests confidence and trust
• Creemos en la justicia suggests belief in the idea or principle of justice

With institutions or systems, confiar en is often the more natural choice when you want to express confidence.

The sentence itself is normal across the Spanish-speaking world. Nothing in Confiamos en la justicia is exclusive to Spain.

What may change is mainly the pronunciation:

• In most of Spain: justicia has the th sound
• In Latin America: justicia usually has an s sound

But grammatically and vocabulary-wise, the sentence works perfectly well in both Spain and Latin America.
