Paul fait l’appel d’urgence et alerte le secouriste.

French often uses faire + a noun where English might prefer a simple verb.

So faire l’appel d’urgence means something like to make/place the emergency call.

A few notes:

• fait is from faire = to do / to make
• l’appel d’urgence = the emergency call

In more everyday French, you might also hear:

• Paul appelle les secours = Paul calls emergency services
• Paul passe un appel d’urgence = Paul places an emergency call

So the structure in your sentence is normal to understand as Paul makes the emergency call.

Because French avoids putting le directly before a vowel sound.

Le becomes l’ before a word that starts with a vowel or silent h:

• le appel → l’appel
• le ami → l’ami
• le homme → l’homme

This is called elision.

So:

• le
  • appel becomes l’appel

This is the same kind of thing: de becomes d’ before a vowel sound.

So:

• de urgence → d’urgence

Here d’urgence means of emergency or, more naturally in English, emergency.

So l’appel d’urgence literally means the call of emergency, but in natural English we say the emergency call.

Both are in the present indicative.

• fait = does / makes
• alerte = alerts

They are both third-person singular because the subject is Paul.

So:

• Paul fait...
• Paul alerte...

This is the normal present tense form used for facts, descriptions, or actions happening in the scene.

Because French, like English, does not need to repeat the subject when the same subject does two actions joined by et.

So:

• Paul fait l’appel d’urgence et alerte le secouriste.

means:

• Paul makes the emergency call and alerts the rescuer.

The subject Paul applies to both verbs:

• fait
• alerte

You could repeat Paul, but it would sound heavier and usually unnecessary:

• Paul fait l’appel d’urgence et Paul alerte le secouriste.

Because alerter takes a direct object in French.

So you alert someone directly:

• alerter quelqu’un = to alert someone

That is why the sentence says:

• alerte le secouriste

and not:

• alerte au secouriste

This is a good example of how French verb patterns do not always match English prepositions exactly.

Other examples:

• Il alerte la police.
• Elle alerte le médecin.

Secouriste means a rescuer, first-aider, or emergency responder, depending on context.

It usually refers to someone trained to give first aid or emergency assistance.

It does not always mean the same thing as:

• médecin = doctor
• ambulancier = ambulance worker / paramedic driver
• pompier = firefighter

So secouriste is a fairly broad emergency-help word, often centered on rescue or first aid.

Le secouriste uses the definite article, so it means the rescuer rather than a rescuer.

This usually suggests that the person is already identifiable in the situation:

• maybe there is one specific rescuer nearby
• maybe the context has already introduced that person
• maybe the speaker is referring to the rescuer involved in this emergency

If the sentence said un secouriste, it would mean a rescuer in a less specific way.

It is understandable and natural enough, but French very often uses other expressions too, depending on context.

Common alternatives include:

• appeler les secours = to call emergency services
• passer un appel d’urgence = to place an emergency call
• lancer l’alerte = to raise the alarm

So your sentence is fine, but in real-life spoken French, learners should also recognize these other common ways of expressing the same general idea.

The structure is:

• Paul = subject
• fait = first verb
• l’appel d’urgence = object/complement of the first verb
• et = and
• alerte = second verb
• le secouriste = direct object of the second verb

So the sentence is built like this:

Subject + verb + object + and + verb + object

That makes it a very useful model sentence for learners, because it shows one subject doing two actions in sequence.

A simple approximation for an English speaker would be:

• fait ≈ feh
• alerte ≈ ah-lert

A couple of helpful points:

• fait is usually pronounced like fè
• the final -te in alerte is pronounced, unlike many silent endings in French
• appel sounds roughly like ah-pel

So the whole sentence sounds approximately like:

Paul fè lah-pel dur-zhans eh ah-lert luh suh-koor-eest

That is only an approximation, but it can help you get started.
