Le voyageur voit l’annulation et demande le réacheminement.

Le voyageur means the traveler, while un voyageur means a traveler.

French often uses the definite article le / la / les when the person or thing is already understood from context, or when speaking about a specific person in a situation. So this sentence is talking about the traveler in question, not just any traveler.

Voit is the 3rd person singular present-tense form of voir (to see).

The subject is Le voyageur, which is he / the traveler, so the verb must match that subject:

• je vois = I see
• tu vois = you see
• il / elle / on voit = he / she / one sees

So:

• Le voyageur voit = The traveler sees

Voit is pronounced roughly like vwah.

Important points:

• the v is pronounced
• oi in modern French usually sounds like wah
• the final t is silent

So voit does not sound like the English word voit would.

Because annulation begins with a vowel sound, French uses elision:

• la + annulation becomes l’annulation

This is very common in French:

• l’hôtel instead of le hôtel
• l’école instead of la école
• l’ami instead of le ami

So l’ can stand for either le or la, depending on the gender of the noun.

It is feminine: la annulation, which becomes l’annulation before a vowel.

You can tell in a dictionary entry because it will usually appear as:

• annulation (f.)

That means:

• une annulation
• l’annulation

Usually, yes. In this context, annulation means cancellation.

For example, in travel or transport contexts, it can refer to the cancellation of:

• a flight
• a train
• a booking
• a trip

So here, voit l’annulation means the traveler sees or becomes aware of the cancellation.

Because in French, demander often takes a direct object when you are asking for a thing.

So:

• demander quelque chose = to ask for something
• demander le réacheminement = to request rerouting / rebooking

Compare:

• Il demande de l’aide. = He asks for help.
• Il demande le remboursement. = He requests the refund.

But if you ask someone, French uses à:

• demander quelque chose à quelqu’un = to ask someone for something

Example:

• Le voyageur demande le réacheminement à l’agent.
  = The traveler asks the agent for rerouting.

Réacheminement is a transport/travel word meaning something like:

• rerouting
• reaccommodation
• sometimes rebooking onto another route/service

It comes from the idea of sending someone or something along a route again:

• acheminer = to route / dispatch / send onward
• réacheminer = to reroute / send onward again
• réacheminement = rerouting

In travel contexts, it usually means arranging a new way for the passenger to reach the destination after a disruption.

Yes, réacheminement is masculine, so it takes le:

• le réacheminement

Many French nouns ending in -ment are masculine, and this is one of them.

So the sentence has:

• l’annulation = feminine
• le réacheminement = masculine

Here it is the verb: demande = asks for / requests.

That is because it follows the subject Le voyageur and matches the sentence structure:

• Le voyageur voit ... et demande ...

French also has the noun une demande, meaning a request, but that is not what is happening here.

Compare:

• Le voyageur demande le réacheminement. = The traveler requests rerouting.
• La demande du voyageur est acceptée. = The traveler’s request is accepted.

Because the sentence is simply describing what happens, in a neutral present-tense way:

• voit = sees
• demande = asks for / requests

French uses the present tense in many of the same ways English does. Depending on context, English might translate this as:

• The traveler sees the cancellation and requests rerouting.
• The traveler sees the cancellation and asks for rerouting.

So the present tense here is straightforward.

French does not need to repeat the subject when the same subject continues with another verb linked by et.

So:

• Le voyageur voit l’annulation et demande le réacheminement.

means:

• The traveler sees the cancellation and requests rerouting.

The subject Le voyageur applies to both verbs:

• voit
• demande

You could repeat it, but it would usually sound unnecessary:

• Le voyageur voit l’annulation et le voyageur demande le réacheminement.

That is grammatically possible, but awkward unless you want special emphasis.

A careful approximate pronunciation is:

luh vwah-yuh-ZHOOR vwah lan-nu-la-syon ay duh-MAHND luh ray-a-shuh-mi-ne-MAHN

A few useful points:

• Le voyageur: the final r is pronounced in French, but softly in the throat.
• voit: final t is silent.
• l’annulation: the l’ links smoothly into the next word.
• et is usually pronounced ay.
• demande: the last e is silent.
• réacheminement is a long word, but the final -ment here is pronounced like mahn.

Depending on accent and speaking speed, details may vary a bit, but those are the main features.

Usually, in a sentence like this, demande is best understood as asks for or requests, not necessarily demands in the forceful English sense.

French demander is broader than English demand. It often simply means:

• to ask
• to request
• to ask for

So here, unless the context clearly shows anger or insistence, a learner should understand demande as requests or asks for.
