Je couvre le bébé avec une couverture parce qu’il fait froid.

Because couvre is the conjugated present-tense form of the verb couvrir (to cover).

• couvrir = the infinitive, like to cover
• je couvre = I cover / I am covering

In this sentence, the subject is je (I), so the verb has to be conjugated:

• je couvre
• tu couvres
• il/elle couvre
• nous couvrons
• vous couvrez
• ils/elles couvrent

So Je couvre le bébé... means I cover the baby...

In French, you usually use an article where English often does too, and sometimes where English might leave it out.

• le bébé = the baby

Here, bébé is a masculine noun, so the definite article is le.

French nouns normally need an article:

• le bébé = the baby
• un bébé = a baby

You would not normally just say Je couvre bébé in standard French.

Because couverture is a feminine noun.

That means:

• une couverture = a blanket
• la couverture = the blanket

So the article must agree with the noun’s gender:

• masculine: un / le
• feminine: une / la

Here:

• bébé is masculine → le bébé
• couverture is feminine → une couverture

No. Couverture can mean different things depending on context.

In this sentence, it means blanket.

But it can also mean things like:

• coverage
• cover
• book cover

That is very common in French: one word can have several related meanings, and the context tells you which one is meant.

Here, because of Je couvre le bébé avec une couverture, the meaning is clearly blanket.

Avec means with.

In this sentence, it introduces the thing being used to cover the baby:

• Je couvre le bébé avec une couverture
• I cover the baby with a blanket

So avec une couverture tells you what the speaker is using.

This is very natural French. You may also sometimes see couvrir quelqu’un d’une couverture, but avec une couverture is straightforward and easy to understand.

This is called elision.

Que becomes qu’ before a word starting with a vowel sound, including silent h.

So:

• parce que il fait froid → not used
• parce qu’il fait froid → correct

French does this to make pronunciation smoother.

Other common examples:

• que elle → qu’elle
• que on → qu’on
• je aime → j’aime

Il fait froid is the normal French way to say it is cold.

Literally, it is something like it makes cold or it does cold, but you should learn it as a fixed weather expression:

• il fait froid = it is cold
• il fait chaud = it is hot
• il fait beau = the weather is nice
• il fait mauvais = the weather is bad

The il here does not refer to the baby. It is an impersonal il, like the it in English weather expressions:

• It is cold
• It is raining

So in this sentence, il means it, not he.

Parce que means because and introduces the reason.

So:

• Je couvre le bébé avec une couverture parce qu’il fait froid.
• I cover the baby with a blanket because it is cold.

This is the most common, neutral way to say because in everyday French.

Learners also often see car, which can also mean because, but parce que is more common in normal speech.

It is grammatical and clear, but native speakers might also say:

• Je couvre le bébé avec une couverture.
• Je mets une couverture sur le bébé.

Both are understandable. The second can sound a bit more everyday in some contexts, because it focuses on putting a blanket on the baby.

Still, your sentence is perfectly good French and clearly expresses the idea.

French word order here is fairly similar to English:

• Je = subject
• couvre = verb
• le bébé = direct object
• avec une couverture = prepositional phrase
• parce qu’il fait froid = reason clause

So the structure is:

Subject + verb + object + with-phrase + because-clause

That is why the sentence looks like:

Je couvre le bébé avec une couverture parce qu’il fait froid.

It is a normal and natural French sentence pattern.

Bébé is pronounced roughly bay-BAY.

A few helpful points:

• both é sounds are like a clear ay sound
• the stress in French is not as strong as in English
• the final é is pronounced, so it is not like English baby

So it sounds approximately like:

• bé-bé → bay-bay

Usually, the t in fait is not pronounced here.

So:

• il fait froid sounds roughly like eel fay frwah

A few notes:

• il sounds like eel
• fait sounds like fay
• froid sounds roughly like frwah

There is no normal liaison between fait and froid here.

No, not in this sentence.

Here, il fait froid is a fixed weather expression meaning it is cold.

If you wanted to say because he is cold, you would normally say:

• parce qu’il a froid = because he is cold

This is an important difference:

• il fait froid = it is cold
• il a froid = he is cold

So in your sentence, the idea is:

• I cover the baby with a blanket because the weather/temperature is cold not
• because he is cold

Because couverture is feminine, so the definite article must be la, not le.

• la couverture = the blanket
• une couverture = a blanket

Use:

• le for masculine singular nouns
• la for feminine singular nouns

So:

• le bébé
• la couverture

Yes. You could say:

• Je le couvre avec une couverture parce qu’il fait froid.

Here, le means him/it and replaces le bébé.

But be careful: if you then say parce qu’il fait froid, the il still means it, not the baby.

So the sentence would still mean:

• I cover him with a blanket because it is cold.

This is a good example of how French pronouns can look ambiguous at first, even when the meaning is clear from the expression.
