Parliamo di fede.

Parliamo is the 1st person plural form of parlare (to speak / to talk), so it means we speak or we talk.

In this sentence, it is usually understood as we talk.

Italian often omits subject pronouns when they are not needed, because the verb ending already shows who the subject is.

• parlo = I speak
• parli = you speak
• parla = he/she speaks
• parliamo = we speak
• parlate = you all speak
• parlano = they speak

So Parliamo di fede already clearly means We talk about faith.
You could say Noi parliamo di fede, but noi would usually add emphasis, like We are the ones talking about faith.

After parlare, Italian commonly uses di to mean about.

So:

• parlare di qualcosa = to talk about something

Examples:

• Parliamo di politica = We’re talking about politics
• Parlate di cinema? = Are you talking about cinema?
• Hanno parlato di te = They talked about you

English uses about, but Italian usually uses di in this pattern.

Italian often leaves out the article with abstract ideas, especially when speaking generally.

So:

• Parliamo di fede = We’re talking about faith, as a concept in general

If you add an article, the meaning can become more specific or stylistically different:

• la fede can mean faith in a more definite or identifiable sense
• la fede can also mean wedding ring, depending on context

In this sentence, di fede sounds natural for the broad abstract idea.

It can mean both, depending on context.

Literally, parliamo is the present tense:

• we talk / we are talking

But Italian also uses the 1st person plural present to make a suggestion:

• Parliamo di fede. = Let’s talk about faith.

So the sentence could mean:

• We’re talking about faith
• Let’s talk about faith

Context tells you which one is intended.

Both are possible translations of parlare, but in this sentence talk about is the most natural English choice because of di fede.

• speak often focuses more on the act of speaking or on language
• talk often sounds more natural for discussing a topic

So:

• Parliamo di fede → We talk about faith / Let’s talk about faith

If the sentence were about language, you might translate differently:

• Parlo italiano = I speak Italian

Fede is a noun. In this sentence it means faith.

It is generally feminine:

• la fede

Examples:

• Ho fede = I have faith
• La fede è importante = Faith is important

As mentioned, fede can also mean wedding ring in some contexts, but here it clearly means faith.

The structure is:

• Parliamo = verb
• di fede = prepositional phrase (about faith)

Italian often allows flexible word order, but this is a very normal and natural order.

If you included the subject, it would be:

• Noi parliamo di fede

But leaving out noi is more common.

A simple pronunciation guide is:

par-LYAH-mo dee FEH-deh

More approximately in IPA: /parˈljaːmo di ˈfeːde/

A few helpful points:

• gli is not in this sentence, so parliamo is easier than it may look
• ia in -liamo glides together: lya
• di sounds like dee
• fede has two clear syllables: fe-de

Yes, but it means something slightly different.

• Parliamo di fede = We talk about faith, We are talking about faith, or Let’s talk about faith
• Stiamo parlando di fede = We are talking about faith right now, more explicitly

So stiamo parlando is more specifically progressive, while parliamo is more flexible and often more natural in many contexts.

It is neutral and natural. There is nothing especially formal or informal about it.

• Parliamo di fede could be used in conversation, teaching, writing, or discussion.
• Its tone depends mostly on context and voice.

It sounds like a normal, standard Italian sentence.
