Paul fait la fête après la réunion.

Faire is the infinitive, meaning to do / to make. In this sentence, the verb has to be conjugated to match the subject Paul, which is he.

So:

• faire = infinitive
• il fait = he does / he makes

Since Paul is third-person singular, French uses fait:

• Paul fait la fête

Faire la fête is a very common French expression. It is idiomatic, and it means something like:

• to party
• to celebrate
• to have a good time

French often uses faire in fixed expressions where English uses a single verb.

Here, faire la fête does not literally mean to make the party. It functions as a set phrase.

Compare:

• Paul fait la fête. = Paul is partying.
• Paul fête son anniversaire. = Paul is celebrating his birthday.

So faire la fête is the natural expression when you mean to party in general.

Not necessarily. In faire la fête, la fête is part of the fixed expression. Even when no specific party has been mentioned, French still normally says faire la fête.

So the article la is required because that is how the expression is built:

• faire la fête

It often works more like an idiom than a literal noun phrase.

They are related, but they are not used in exactly the same way.

• faire la fête = to party / celebrate in a lively way
• fêter = to celebrate something

Examples:

• Ils font la fête ce soir. = They’re partying tonight.
• Ils fêtent leur victoire. = They’re celebrating their victory.

A key difference is that fêter usually takes a direct object:

• fêter un anniversaire
• fêter une victoire
• fêter Noël

But faire la fête is a complete expression on its own.

Yes—this is a common false friend.

In French, une réunion usually means:

• a meeting

It does not usually mean an emotional family reunion the way English reunion often does.

So:

• après la réunion = after the meeting

If you want the idea of people meeting again after being apart, French would usually use a different expression depending on context, not simply une réunion in most everyday cases.

Because après is a preposition that can be followed directly by a noun phrase.

So you say:

• après la réunion = after the meeting
• après le dîner = after dinner
• après le travail = after work

You do not add de before the noun here.

Yes, but not in the same way as with a noun.

If après is followed by a verb, French usually uses:

• après avoir + past participle
• après être + past participle

Examples:

• Après avoir mangé, Paul fait la fête. = After eating, Paul parties.
• Après être arrivé, il appelle Marie. = After arriving, he calls Marie.

So:

• après la réunion = after the meeting
• après avoir terminé la réunion = after finishing the meeting

Yes. Fait is in the present tense.

So the sentence is grammatically present:

• Paul fait la fête après la réunion.

Depending on context, the French present can mean:

• something happening now
• something habitual
• something scheduled or generally true

For example, it could mean:

• Paul parties after the meeting today.
• Paul usually parties after the meeting.
• Paul is partying after the meeting.

French present tense is often a bit broader than English simple present.

Yes. French can move the time phrase for emphasis or style.

These are both correct:

• Paul fait la fête après la réunion.
• Après la réunion, Paul fait la fête.

The second version puts more focus on after the meeting.

The basic meaning stays the same.

A careful pronunciation would be roughly:

Paul fait la fête après la réunion
/pɔl fɛ la fɛt apʁɛ la ʁeynjɔ̃/

A few helpful notes:

• Paul sounds roughly like Pol
• fait sounds like fay
• fête sounds like fet
• après sounds like ah-preh
• réunion has several syllables: ray-yoo-nyon

Also, the final consonants in French are often silent, so:

• Paul: the l is pronounced
• fait: the final t is silent
• après: the final s is silent

Yes, depending on context, faire la fête can range from:

• to party
• to celebrate
• to have a festive good time

If the context is lively and social, party is often the best translation. If the context is more general, celebrate can also work.

So the exact English choice depends on tone:

• casual, lively: Paul is partying after the meeting
• broader: Paul is celebrating after the meeting

But in most everyday situations, learners should recognize faire la fête as a standard expression meaning to party.
