La carrosserie est propre.

In French, you usually use an article with singular countable nouns. So la carrosserie means the bodywork.

French uses articles more often than English does. Where English might say Bodywork is clean, French normally says La carrosserie est propre.

Because carrosserie is a feminine noun in French. Noun gender is a grammatical feature, and it does not always match biological sex or anything logical in English.

You can tell it is feminine here because it takes the article la:

• la carrosserie

Many nouns ending in -erie are feminine, so that pattern can help.

Carrosserie usually refers to the bodywork or outer body of a vehicle. It is not the whole car in general, but specifically the body/shell/exterior structure.

So this sentence is talking about the condition of the vehicle’s bodywork.

Est is the third-person singular form of the verb être, which means to be.

So:

• je suis = I am
• tu es = you are
• il / elle / on est = he / she / one is

Since la carrosserie is singular, French uses est:

• La carrosserie est propre = The bodywork is clean

Because in this sentence, propre is not directly attached to the noun inside a noun phrase. It comes after the verb est and works as an adjective describing the subject.

Structure:

• La carrosserie = subject
• est = is
• propre = clean

This is the same basic pattern as in English:

• The bodywork is clean

So propre is after the verb, not just after the noun.

It actually already matches the feminine singular noun, but propre is one of those adjectives whose masculine singular and feminine singular forms look the same in spelling.

Compare:

• masculine singular: propre
• feminine singular: propre
• masculine plural: propres
• feminine plural: propres

So with la carrosserie (feminine singular), propre is correct, even though it looks unchanged.

Yes. Both the article and the verb would change, and the adjective would usually add -s in writing.

For example:

• Les carrosseries sont propres. = The bodyworks / body panels are clean.

Changes:

• la → les
• est → sont
• propre → propres

A careful pronunciation would be approximately:

la ka-ro-suh-REE eh PROPR

A more natural French pronunciation is smoother, with the sounds flowing together. A rough IPA version is:

/la ka.ʁɔs.ʁi ɛ pʁɔpʁ/

A few points:

• r is the French r, not the English one.
• The final e in propre is not pronounced.
• est here is pronounced like eh.

No, normally there is no liaison here.

You would say:

• est propre = eh propr

Not:

• eh-t propr

That is because liaison after est before a consonant like p does not happen here.

Yes. Propre can have several meanings depending on context.

Most commonly, it means:

• clean

But it can also mean:

• one’s own in expressions like ma propre voiture = my own car

In La carrosserie est propre, the meaning is clearly clean.

Yes. That means something like The bodywork is nice and clean or really clean.

Adding bien can make the description sound a bit stronger or more natural in conversation:

• La carrosserie est propre. = The bodywork is clean.
• La carrosserie est bien propre. = The bodywork is very/quite clean.

Yes, especially if you are specifically talking about the vehicle’s exterior bodywork. It sounds natural in contexts like car sales, repairs, inspections, or describing condition.

Depending on context, French speakers might also say things like:

• La voiture est propre. = The car is clean.
• La carrosserie est en bon état. = The bodywork is in good condition.

So your sentence is correct and natural when the bodywork itself is the focus.
