L’enfant a le front chaud, alors sa mère appelle le médecin.

Here, le front means forehead.

That can surprise English speakers because French front does not usually mean the same thing as everyday English front in this kind of sentence. In other contexts, front can also mean front or battlefront, but with a person’s body, le front means forehead.

So:

• le front = forehead
• avoir le front chaud = to have a warm forehead

Because enfant begins with a vowel sound.

In French, le and la become l’ before a vowel or a silent h:

• le enfant → l’enfant
• la école → l’école
• le homme → l’homme

So l’enfant is just the normal contracted form.

It is the verb a, from avoir.

• a = has
• à = to, at

They sound the same, but they are different words.

In this sentence:

• L’enfant a le front chaud = The child has a warm forehead

So a is the third-person singular present of avoir.

French often uses avoir with a body part to describe a condition affecting that body part.

So:

• L’enfant a le front chaud = literally The child has the forehead warm

This is a natural French way to say that the child’s forehead is warm.

If you said:

• L’enfant est chaud

that would sound more like The child is warm/hot, meaning the whole child, not specifically the forehead.

So avoir + body part + adjective helps French be more specific.

With body parts, French often uses the definite article (le, la, les) instead of a possessive like son or sa, when the owner is already obvious.

Here, it is clear that the forehead belongs to the child, so French naturally says:

• L’enfant a le front chaud

rather than:

• L’enfant a son front chaud

This is a very common French pattern. Compare:

• Il a les mains froides = He has cold hands
• Elle a les yeux bleus = She has blue eyes

English usually prefers his/her, but French often prefers the in these situations.

Because many French adjectives come after the noun.

So:

• le front chaud = the warm forehead

This is the normal position for many descriptive adjectives, including chaud.

Some adjectives come before the noun, but chaud usually comes after it in a phrase like this.

Because front is masculine singular.

French adjectives must agree with the noun they describe:

• masculine singular: chaud
• feminine singular: chaude
• masculine plural: chauds
• feminine plural: chaudes

Since le front is masculine singular, the correct form is chaud.

For comparison:

• la main chaude = the warm hand

Here, alors means so, therefore, or as a result.

It connects the two parts of the sentence:

• the child has a warm forehead
• so the mother calls the doctor

So alors is showing a consequence.

Depending on context, alors can also mean then, but in this sentence so or therefore is the best idea.

It is sa mère because mère is a feminine singular noun.

In French, possessive adjectives agree with the thing possessed, not with the owner.

So:

• sa mère = his mother / her mother
• son père = his father / her father

That means sa can mean either his or her, depending on context.

A native English speaker often expects French possessives to match the owner, but they do not. They match the noun that follows.

Because appeler takes a direct object.

So you say:

• appeler quelqu’un = to call someone

Examples:

• Elle appelle sa mère = She calls her mother
• Il appelle le médecin = He calls the doctor

There is no à after appeler.

This is different from téléphoner, which does use à:

• Elle téléphone au médecin = She phones the doctor

So:

• appeler le médecin = correct
• appeler au médecin = not correct in this meaning

Le médecin suggests a specific doctor, or the doctor as the relevant professional to call in this situation.

French often uses the definite article where English also uses the:

• sa mère appelle le médecin = his/her mother calls the doctor

If you said un médecin, it would mean a doctor, which sounds less specific.

So the difference is roughly:

• le médecin = the doctor
• un médecin = a doctor

A rough pronunciation guide is:

• L’enfant ≈ lahn-fahn
• a ≈ ah
• le front ≈ luh fron with a nasal ending, and the t is silent
• chaud ≈ show
• alors ≈ ah-lor
• sa mère ≈ sa mehr
• appelle ≈ ah-pell
• le médecin ≈ luh med-seh(n), with a nasal ending

A few useful pronunciation points:

• final t in enfant is silent
• final t in front is silent
• final d in chaud is silent
• è in mère gives an eh sound
• médecin ends with a nasal vowel, so the final n is not pronounced like a strong English n

French also does not stress words the same way English does; the rhythm is smoother across the whole phrase.
