Les parties communes sont propres.

Les is the plural form of the in French.

So les parties communes means the common areas or the shared parts.

It is plural because the noun parties is plural: the sentence is talking about more than one area/part.

In this context, les parties communes is a common expression, especially in buildings, apartment blocks, or condominiums. It refers to the shared areas or common parts of a building, such as:

• hallways
• stairwells
• entrances
• shared gardens
• elevators

So this is not about political parties. Here, parties means parts/sections/areas.

The singular noun is une partie (a part, a section, an area). It is a feminine noun.

That gives you:

• singular: la partie
• plural: les parties

Because the noun is feminine plural, any adjective describing it must also be feminine plural.

Commun is the adjective meaning common/shared.

French adjectives usually agree with the noun they describe. Since parties is feminine plural, commun changes to communes:

• masculine singular: commun
• feminine singular: commune
• masculine plural: communs
• feminine plural: communes

So les parties communes is correct because parties is feminine plural.

Sont is the third-person plural form of the verb être (to be).

The subject is les parties communes, which is plural, so French uses sont:

• la partie commune est propre = the common area is clean
• les parties communes sont propres = the common areas are clean

So sont simply means are here.

Because propres is agreeing with les parties communes, which is plural.

The adjective propre can mean clean in this sentence. Its forms are:

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

So the singular and plural are spelled differently only in the plural form, with an added s.

Since the noun phrase is plural, French uses propres.

No, not in this sentence.

Propre can mean different things depending on context:

• clean
• one’s own

Here, because it comes after être and describes the state of the common areas, it means clean.

Examples:

• Ma chambre est propre. = My room is clean.
• Ma propre chambre. = My own room.

So in Les parties communes sont propres, the meaning is definitely clean.

These two adjectives are doing different jobs.

1. communes is directly describing the noun parties inside the noun phrase:

   • les parties communes
   • literally: the common parts/areas

2. propres comes after the verb sont because it is the predicate adjective:

   • sont propres
   • are clean

So the structure is:

• Subject: Les parties communes
• Verb: sont
• Description: propres

This is very normal in French.

Because propres is an adjective linked to the subject by the verb être.

In French, after être, adjectives normally do not take an article:

• La salle est grande.
• Les couloirs sont étroits.
• Les parties communes sont propres.

This works much like English:

• The room is big
• not The room is a big

So propres is just an adjective, not a noun phrase.

Usually, this kind of sentence is understood as a general statement or observation: the common areas are clean.

French simple present (sont) can cover both:

• a general fact
• a current description

So depending on context, it could mean:

• The common areas are clean (right now)
• The common areas are kept clean / are generally clean

The sentence itself does not force one interpretation.

A careful pronunciation is roughly:

lay par-tee ko-myun son pro-pruh

More accurately in IPA:

/le paʁti kɔmyn sɔ̃ pʁɔpʁ/

A few useful notes:

• les sounds like lay
• parties sounds like par-tee
• communes sounds like ko-myun
• sont has a nasal vowel, so the n is not fully pronounced like an English n
• the final s in communes and propres is silent

Yes. The singular version would be:

La partie commune est propre.

That means The common area is clean or The shared part is clean.

Notice how everything changes to singular:

• les → la
• parties → partie
• communes → commune
• sont → est
• propres → propre
