La copropriété est grande.

Because copropriété is a feminine singular noun in French, so it takes the feminine singular definite article la.

A good habit in French is to learn nouns together with their article:

• la copropriété
• not just copropriété

That helps you remember the noun’s gender.

Copropriété is a noun used for a property that is jointly owned, and in everyday French it often refers to a condominium building/system of shared ownership, or sometimes the group/legal structure of co-owners.

So depending on context, it can refer to:

• the shared-ownership property itself
• the condo building
• the condominium arrangement
• the co-ownership association

Even if the English meaning has already been given, learners often notice that this word can be a bit broader than a single simple English word.

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

The subject is la copropriété, which is singular, so French uses:

• la copropriété est = the condominium/shared property is

This is the same pattern as:

• La maison est grande.
• La ville est belle.

Because French adjectives usually agree in gender and number with the noun they describe.

Here:

• copropriété is feminine singular
• so grand becomes grande

Basic pattern:

• masculine singular: grand
• feminine singular: grande
• masculine plural: grands
• feminine plural: grandes

So:

• Le bâtiment est grand.
• La copropriété est grande.

Because this sentence uses être + adjective.

In French, just like in English, when an adjective comes after to be, it describes the subject:

• La copropriété est grande.
• The condominium/shared property is large.

So grande is not directly placed after the noun here; it comes after the verb because it is a predicate adjective.

That is a great question. In French, some adjectives can come before the noun when they directly modify it:

• une grande maison

But in your sentence, the structure is different:

• La copropriété est grande

Here, grande is not sitting next to the noun as part of the noun phrase. It is linked to the subject by est. So it must come after the verb.

Compare:

• une grande copropriété = a large condominium/shared property
• La copropriété est grande = The condominium/shared property is large

A simple approximate pronunciation is:

la ko-pro-pri-é-tay ay grahnd

A bit more carefully:

• la = la
• copropriété = ko-pro-pri-é-té
• est = usually pronounced like é in connected speech
• grande = grahnd

A few pronunciation notes:

• The é sound in copropriété is a clear ay sound.
• The final -e in grande is usually silent.
• In normal speech, est is often smoothly connected to the next word.

Usually, yes. In grande, the final -d is pronounced.

So:

• grand often sounds like grahn
• grande sounds like grahnd

That is one audible difference between the masculine and feminine forms of this adjective.

No, not in a normal sentence like this.

In French, nouns used as the subject of a sentence usually need an article or some other determiner:

• La copropriété est grande.
• not Copropriété est grande.

French uses articles more often than English does, so this is something English speakers often have to get used to.

Yes, depending on context, many speakers do use copropriété in a practical, everyday way to refer to the building or the condo property as a whole.

But context matters, because copropriété can also emphasize the shared-ownership arrangement rather than just the physical building.

So in real life, the sentence could mean something like:

• the condo building is large
• the shared property is large
• the condominium complex is large

The plural would be:

Les copropriétés sont grandes.

Here is what changes:

• la → les
• copropriété → copropriétés
• est → sont
• grande → grandes

That is because both the noun and adjective become plural, and the verb must also match the plural subject.
