La penderie est assez grande pour mes manteaux, et il reste encore deux cintres libres.

Because penderie is a feminine singular noun, and the adjective must agree with it.

• la penderie = feminine singular
• grand = masculine singular
• grande = feminine singular

So:

• La penderie est assez grande = The wardrobe/closet is big enough

This is standard adjective agreement in French.

Penderie usually refers to a place for hanging clothes, such as:

• a wardrobe
• a hanging closet
• the hanging section of a closet

It is related to the verb pendre / suspendre in the sense of hanging. In this sentence, it suggests a storage space where coats can be hung on hangers.

It is a bit more specific than a general armoire, because penderie emphasizes clothes hanging space.

Assez ... pour ... means enough ... for ... or sufficiently ... for ....

So:

• assez grande = big enough
• pour mes manteaux = for my coats

Together:

• assez grande pour mes manteaux = big enough for my coats

This is a very common pattern in French:

• assez grand pour moi = tall/big enough for me
• assez riche pour voyager = rich enough to travel
• assez chaud pour sortir = warm enough to go out

French often expresses this idea more directly with pour.

• pour mes manteaux literally means for my coats
• In natural English, we often say big enough for my coats or big enough to hold my coats

French does not always need an extra verb like hold or fit if the meaning is already clear from context.

If you wanted to be more explicit in French, you could say something like:

• assez grande pour contenir mes manteaux
• assez grande pour y mettre mes manteaux

But the original sentence is completely natural and idiomatic.

Because the speaker is talking about their own coats, not coats in general.

• mes manteaux = my coats
• des manteaux = some coats / coats

So:

• pour mes manteaux = for my coats

French uses possessive adjectives very regularly where English does too:

• mon livre = my book
• tes chaussures = your shoes
• nos valises = our suitcases

Here, il is an impersonal subject. It does not refer to a specific masculine noun like manteau or cintre.

Il reste ... is a common French structure meaning:

• there remains ...
• there is/are ... left

So:

• il reste encore deux cintres libres = there are still two free hangers left

This is similar to other impersonal French expressions:

• il y a = there is / there are
• il faut = it is necessary / one must
• il semble = it seems

So do not try to translate il here as he or it referring to something specific.

It comes from the verb rester, which often means:

• to remain
• to stay
• to be left

In this sentence, it means to be left / to remain available:

• il reste deux cintres = two hangers remain / there are two hangers left

Other examples:

• Il reste du pain. = There is some bread left.
• Il reste trois minutes. = Three minutes remain.
• Je reste à la maison. = I am staying at home.

So rester can mean either stay or remain, depending on context.

Here, encore means still.

So:

• il reste encore deux cintres libres = there are still two free hangers left

It adds the idea that, even after putting things away, two hangers remain available.

Encore can have several meanings depending on context:

• still → Il travaille encore. = He is still working.
• again → Dis-le encore. = Say it again.
• another / more → J’en veux encore. = I want more.

In this sentence, still is the right idea.

Because in French, most adjectives come after the noun.

• deux cintres libres = two free hangers

This is the normal adjective position for many descriptive adjectives, especially ones like:

• grand
• petit
• libre
• intéressant
• utile

So:

• un cintre libre = a free hanger
• deux cintres libres = two free hangers

French adjective placement is not always the same as English, but here the noun-first order is normal.

Because libres agrees with cintres, which is masculine plural.

• un cintre libre = one free hanger
• deux cintres libres = two free hangers

Agreement here is:

• masculine singular: libre
• feminine singular: libre
• masculine plural: libres
• feminine plural: libres

So the only visible change is the plural s.

Yes, and that is a very useful comparison.

• Il y a encore deux cintres libres = There are still two free hangers.
• Il reste encore deux cintres libres = There are still two free hangers left.

Both are natural, but il reste emphasizes what remains after considering the available space or what has already been used.

So in this sentence, il reste is slightly more precise because the speaker is talking about leftover capacity in the wardrobe.

No. They are quite different.

• très grande = very big
• assez grande = fairly big / big enough, depending on context

In this sentence, assez grande pour mes manteaux clearly means big enough for my coats, not just quite big.

So assez often means:

• quite/fairly, or
• enough

The meaning depends on the structure. With pour here, the enough meaning is very clear.

Because assez is directly modifying the adjective grande.

• assez grande = big enough / quite big

You use de after assez when it is followed by a noun:

• assez de place = enough space
• assez de cintres = enough hangers

But before an adjective, there is no de:

• assez grand
• assez grande
• assez libre

So:

• La penderie est assez grande = correct
• La penderie est assez de grande = incorrect
