Nous allons en parler avec nos amis.

Nous allons parler is the near future in French: aller + infinitive.

• nous allons parler = we are going to talk
• nous parlerons = we will talk

Both can refer to the future, but aller + infinitive is very common in everyday spoken French and often feels a bit more immediate or natural in conversation.

So in this sentence:

• Nous allons en parler = We’re going to talk about it

Here, en is a pronoun that replaces de + thing/idea.

The verb parler often uses de when you say what you are talking about:

• parler de ce problème = to talk about this problem
• en parler = to talk about it

So en means something like about it, about that, or of it, depending on the context.

Example:

• Nous allons parler de ce film.
• Nous allons en parler.

In the second sentence, en replaces de ce film.

French object pronouns usually go before the infinitive when you have a structure like aller + infinitive.

So:

• Nous allons en parler ✔
• Nous allons parler en ✘

A good pattern to remember is:

• je vais le voir
• nous allons en parler
• elle va y aller

The pronoun belongs with the infinitive, and it comes before it.

Both avec and à can appear with parler, but they do not emphasize exactly the same thing.

• parler à quelqu’un = to speak to someone
• parler avec quelqu’un = to speak with someone

In your sentence, avec nos amis suggests a conversation or discussion involving the friends.

So:

• Nous allons en parler avec nos amis = We’re going to talk about it with our friends

If you said à nos amis, it would sound more like speaking to them rather than discussing it together.

Nous is the subject pronoun meaning we.

It tells you who is doing the action:

• Nous = we
• allons = are going

Because the subject is nous, the verb aller must be conjugated as allons.

The full conjugation of aller in the present is:

• je vais
• tu vas
• il/elle/on va
• nous allons
• vous allez
• ils/elles vont

Nos is the possessive adjective meaning our.

It agrees with the noun that follows:

• ami = friend
• amis = friends
• nos amis = our friends

French possessive adjectives change according to the noun, not according to the owner. For our, you get:

• notre
  • singular noun
• nos
  • plural noun

So:

• notre ami = our friend
• nos amis = our friends

That version is also correct.

• Nous allons en parler avec nos amis = We’re going to talk about it with our friends
• Nous en parlerons avec nos amis = We will talk about it with our friends

The difference is mostly one of style and nuance:

• aller + infinitive is very common in everyday speech
• the simple future can sound a bit more formal, planned, or neutral depending on context

In many situations, both are possible.

Yes, very often.

When you say what the topic is, French commonly uses:

• parler de quelque chose = to talk about something
• parler de quelqu’un = to talk about someone

That is why en is used here: it replaces something introduced by de.

Compare:

• Nous parlons de ce projet.
• Nous en parlons.

But French also has:

• parler à quelqu’un = speak to someone
• parler avec quelqu’un = speak with someone

So parler can combine with different prepositions depending on the meaning.

You would say:

• Nous n’allons pas en parler avec nos amis.

With aller + infinitive, the ne ... pas goes around the conjugated verb:

• nous n’allons pas
  • infinitive

Not around parler.

So:

• Nous allons en parler = We are going to talk about it
• Nous n’allons pas en parler = We are not going to talk about it

Yes, there is a common liaison in nous allons:

• nous allons → roughly noo-zah-lon

A simple pronunciation guide for the whole sentence is:

• Nous allons en parler avec nos amis
• roughly: noo-zah-lon ahn par-lay ah-vek no-zah-mee

A few notes:

• nous sounds like noo
• the s in nous links to allons: nous-z-allons
• en is nasal: ahn
• parler ends with an ay sound
• nos amis also has liaison: no-zah-mee

Yes, very often in spoken French.

Instead of:

• Nous allons en parler avec nos amis

you will often hear:

• On va en parler avec nos amis

In everyday spoken French, on often means we. It is less formal and extremely common.

So:

• nous allons = more standard/written or careful spoken French
• on va = very common in everyday speech
