В спальне висят белые жалюзи.

Because after в when it means in a place, Russian normally uses the prepositional case.

• спальня = bedroom
• в спальне = in the bedroom

So спальня changes to спальне because the sentence is talking about location, not motion.

Compare:

• в спальне = in the bedroom
• в спальню = into the bedroom

Russian uses different cases to show the difference:

• в + prepositional = location: in
• в + accusative = motion toward/into

Here we have спальне, which is prepositional, so it means the blinds are already located there.

• В спальне висят жалюзи. = The blinds are in the bedroom / hanging in the bedroom.
• Я иду в спальню. = I am going into the bedroom.

Висят is the 3rd person plural present form of висеть, which means to hang.

Russian often uses a specific verb for the way something is positioned:

• стоять = to stand
• лежать = to lie
• висеть = to hang

Since blinds hang, висеть is the natural verb.

So:

• жалюзи висят = the blinds are hanging

This is more natural in Russian than using a general verb like to be.

Because the subject, жалюзи, is treated as plural.

So the agreement is:

• жалюзи → plural noun
• висят → plural verb
• белые → plural adjective

Even though жалюзи does not change its form, it still behaves grammatically as plural.

Because adjectives in Russian must agree with the noun in number, case, and sometimes gender.

Here жалюзи is plural, so the adjective must also be plural:

• белые = white, plural
• жалюзи = blinds, plural

So белые жалюзи means white blinds.

It is in the nominative plural, because it is the subject of the sentence.

The structure is:

• В спальне = location phrase
• висят = verb
• белые жалюзи = subject

Even though жалюзи itself does not change form, the adjective белые and the plural verb висят show that this noun phrase is functioning as a plural subject.

Because жалюзи is an indeclinable noun. That means its form stays the same instead of changing for case.

It is also normally used only in the plural.

So you can see the grammar from the words around it:

• белые shows plural agreement
• висят shows plural agreement

The noun itself stays жалюзи.

In standard Russian, жалюзи is generally treated as a plural-only noun.

That means Russian speakers usually think of it like blinds in English rather than a blind.

So you get plural agreement:

• эти жалюзи
• белые жалюзи
• жалюзи висят

Because Russian has no articles like a/an/the.

So в спальне висят белые жалюзи can mean things like:

• White blinds are hanging in the bedroom
• The white blinds are hanging in the bedroom
• There are white blinds in the bedroom

Which one sounds best depends on context.

Yes. Russian word order is fairly flexible.

This sentence starts with В спальне to set the scene first:

• В спальне висят белые жалюзи.

Other possible orders include:

• Белые жалюзи висят в спальне.
• В спальне белые жалюзи висят.

The basic meaning stays similar, but the focus can shift a little. Starting with В спальне feels natural if you are talking about what is in that room.

Not exactly. Russian often does not use a separate word for there is/there are in sentences like this.

Instead, it simply says something like:

• In the bedroom hang white blinds.

Natural English adds there are or rearranges the sentence, but Russian often just uses the location plus the verb plus the thing being described.

So В спальне висят белые жалюзи is a normal Russian way to express the idea.

Yes, you could, but it is a little different in feel.

• В спальне есть белые жалюзи. = There are white blinds in the bedroom.
• В спальне висят белые жалюзи. = White blinds are hanging in the bedroom.

Есть focuses more on existence: they are there. Висят gives a more concrete picture: they are hanging.

For blinds, висят is very natural because that is how blinds are positioned.

The main stresses are:

• в спальне → спАльне
• висят → висЯт
• белые → бЕлые
• жалюзи → жалюзИ

The last word is especially worth remembering because the stress is on the final syllable: жалюзИ.

It could, if you wanted a more specific location.

• В спальне висят белые жалюзи. = White blinds are hanging in the bedroom.
• На окне висят белые жалюзи. = White blinds are hanging on the window.

The original sentence gives the broader location: the bedroom. Another sentence could specify exactly where in the room they are.
