Après le déjeuner, nous allons reprendre la route vers le sud.

In French, meals usually take an article:

• le petit déjeuner = breakfast
• le déjeuner = lunch
• le dîner = dinner

So après le déjeuner is the normal way to say after lunch.

French often uses the definite article where English uses no article:

• avant le dîner = before dinner
• pendant le cours = during class

You may sometimes see article-less expressions in other contexts, but for meals, après le déjeuner is the standard choice here.

Yes — this depends on the French-speaking region.

In France:

• petit déjeuner = breakfast
• déjeuner = lunch
• dîner = dinner

In some other varieties of French, especially historically or regionally:

• déjeuner can mean breakfast

In this sentence, le déjeuner means lunch.

Nous allons reprendre is the near future form:

• nous allons reprendre = we are going to resume / get back on
• literally: we are going to take up again

French has two common ways to talk about the future:

1. Near future: aller + infinitive

   • nous allons reprendre
   • often feels a bit more immediate or connected to the present

2. Simple future:

   • nous reprendrons
   • also correct, but slightly more formal or less conversational in many contexts

So this sentence sounds very natural in everyday spoken French.

Reprendre literally means to take again, to resume, or to start again.

In this sentence, it is part of the expression reprendre la route, which means:

• to get back on the road
• to continue the journey
• to set off again

So reprendre here does not mean physically taking a road; it means resuming travel.

Yes, it is a very common expression.

Prendre la route = to hit the road / set out
Reprendre la route = to hit the road again / get back on the road

This is idiomatic French. Even though la route literally means the road, the whole expression refers to continuing a trip.

Similar examples:

• Nous prenons la route tôt demain. = We’re hitting the road early tomorrow.
• Après une pause, ils ont repris la route. = After a break, they got back on the road.

Vers means toward or in the direction of.

So:

• vers le sud = toward the south / southward

This focuses on direction of movement.

By contrast:

• au sud usually means in the south
• it describes a location, not a direction

Compare:

• Nous allons vers le sud. = We’re heading south.
• Nous sommes au sud de la ville. = We are south of the city / in the southern part of the city.

In French, compass directions are usually lowercase when they mean a direction:

• le nord
• le sud
• l’est
• l’ouest

So vers le sud is written with a lowercase s.

You may see capitals when the word is part of a proper name or a recognized region:

• le Sud-Ouest
• l’Amérique du Sud

But in this sentence, it simply means the direction south, so lowercase is correct.

The comma separates the introductory time phrase from the rest of the sentence:

• Après le déjeuner, = after lunch
• nous allons reprendre la route vers le sud. = we’re going to get back on the road southward

This is similar to English, where you often write:

• After lunch, we’re going to head south again.

In French, the comma is common and helps readability, especially when a sentence begins with a phrase like:

• Après le déjeuner, ...
• Le matin, ...
• En été, ...

Yes, absolutely.

• Nous allons reprendre la route = we’re going to get back on the road
• Nous reprendrons la route = we will get back on the road

Both are grammatical. The difference is mainly tone and style:

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

So the version in your sentence is very natural, especially in spoken French.

Yes. In everyday spoken French, on often replaces nous.

So:

• Nous allons reprendre la route = more formal or careful
• On va reprendre la route = very common in conversation

Both mean the same thing here: we’re going to get back on the road.

This is a very important pattern in modern spoken French:

• Nous allons partir → On va partir
• Nous mangeons → On mange

A natural pronunciation would be roughly:

Après le déjeuner, nous allons reprendre la route vers le sud.
→ ah-pray luh day-zhuh-nay, noo zah-lohn ruh-prahn-druh lah root vair luh su(d)

A few useful points:

• Après sounds like ah-pray
• déjeuner has the zh sound, like in measure
• nous allons has a liaison, so it sounds like noo zah-lohn
• sud often has a light final d sound in careful speech, though pronunciation can vary slightly by speaker

The sentence has a smooth rhythm, with a small pause after déjeuner because of the comma.
