در اتاق من یک کمد بزرگ هست، اما کشوهای میز خیلی کوچک هستند.

In Persian, place expressions often come early in the sentence, especially when setting the scene.

So:

در اتاق من = in my room

Literally, the structure is:

در = in
اتاق من = my room

Then the sentence continues with what exists there:

یک کمد بزرگ هست = there is a big wardrobe/closet

So the first part is very natural Persian word order:
In my room, there is a big wardrobe...

Persian usually shows possession by putting the possessor after the noun:

اتاق من = my room
literally: room my

In pronunciation, there is an ezafe sound between them:

اتاقِ من
pronounced roughly: otâq-e man

This -e links the noun to what comes after it. In normal writing, it is often not shown, but native speakers still pronounce it.

It can mean both, depending on context.

Here, in یک کمد بزرگ:

یک = a / one
کمد = wardrobe / closet
بزرگ = big

In this sentence, یک works like the English indefinite article a:

a big wardrobe

So یک کمد بزرگ هست means there is a big wardrobe.

In Persian, adjectives usually come after the noun they describe.

So:

کمد بزرگ = big wardrobe
literally: wardrobe big

In speech, there is again an ezafe link:

کمدِ بزرگ
komod-e bozorg

This is a very common Persian pattern:

• خانه بزرگ = big house
• میز کوچک = small table
• کمد بزرگ = big wardrobe

Because the first subject is singular, and the second one is plural.

• یک کمد بزرگ = a big wardrobe → singular
  so: هست = is

• کشوهای میز = the desk’s drawers / the drawers of the desk → plural
  so: هستند = are

So:

• یک کمد بزرگ هست = there is a big wardrobe
• کشوهای میز ... هستند = the drawers of the desk are ...

Both mean is.

• است is more formal/literary
• هست is very common and natural in everyday speech and writing

So:

• کمد بزرگ است
• کمد بزرگ هست

Both are correct, but هست often sounds more conversational.

Similarly, هستند means are.

This is a great example of Persian noun linking.

Start with:

کشو = drawer

Make it plural:

کشوها = drawers

Now link it to another noun with ezafe:

کشوهای میز
pronounced roughly: keshuhâ-ye miz

This means:

the drawers of the desk/table

So the structure is:

کشو + ها + ی + میز

• کشو = drawer
• ها = plural marker
• ی / ezafe = linking sound
• میز = desk / table

A very literal breakdown would be:

drawers-of desk

Persian does not have a word exactly like English the.

Whether something is definite or indefinite is usually understood from context.

So:

• یک کمد = a wardrobe
• کشوهای میز = the desk’s drawers / the drawers of the desk

Even without a word for the, the phrase sounds definite because it refers to a specific object: the drawers belonging to the desk.

خیلی means very.

So:

کوچک = small
خیلی کوچک = very small

In Persian, adverbs like خیلی usually come before the adjective they modify, just like in English:

• خیلی بزرگ = very big
• خیلی خوب = very good
• خیلی کوچک = very small

Yes. اما means but.

It connects two contrasting ideas:

• there is a big wardrobe in my room
• but the desk drawers are very small

So the overall structure is:

..., اما ... = ..., but ...

It is a very common conjunction in Persian.

میز can mean both table and desk.

The exact meaning depends on context.

In this sentence, because it has drawers, English would usually translate it as desk:

کشوهای میز = the desk drawers

But in other contexts, میز could simply mean table.

A natural pronunciation would be roughly:

dar otâq-e man yek komod-e bozorg hast, ammâ keshuhâ-ye miz kheili kuchak hastand

The important linking points are:

• اتاقِ من
• کمدِ بزرگ
• کشوهایِ میز

Those -e sounds are very important in natural Persian pronunciation, even when they are not fully written.

Yes. Persian often allows some flexibility in word order, but this sentence is very natural as written.

For example, the first clause could also be phrased in slightly different ways in speech, but:

در اتاق من یک کمد بزرگ هست

is perfectly normal and clear.

The given version is a good standard pattern to learn:

place + thing + description + is/are

So it is a very useful model sentence for beginners.
