На кровати лежит чистое покрывало.

Because на here means on, and with location it normally takes the prepositional case.

• dictionary form: кровать = bed
• after на for location: на кровати = on the bed

So:

• на кровати = on the bed
• not на кровать, because that would suggest motion onto the bed in a different pattern

This is a very common contrast in Russian:

• на кровати = on the bed (location)
• на кровать = onto the bed (direction, motion)

Лежит comes from лежать, which means to lie or to be lying.

Russian often prefers more specific position verbs where English just uses is:

• лежать = to lie
• стоять = to stand
• сидеть = to sit

So instead of simply saying The blanket is on the bed, Russian says something closer to:

• On the bed lies a clean blanket

For an object like a blanket or bedspread, лежит is natural because it is resting flat on a surface.

In the present tense, Russian usually leaves out to be.

So English:

• The blanket is clean
• The blanket is on the bed

often becomes Russian without a present-tense is.

But in this sentence, you do have a verb: лежит. That verb already expresses the main idea: is lying / lies.

So the sentence is not missing anything. It is a complete sentence.

Both are possible.

Russian word order is more flexible than English. The version you have:

• На кровати лежит чистое покрывало

puts the location first. This can sound natural when introducing the scene or drawing attention to where something is.

Another normal version is:

• Чистое покрывало лежит на кровати

That puts more focus on the blanket/bedspread itself.

Very roughly:

• На кровати лежит чистое покрывало = On the bed there is / lies a clean bedspread
• Чистое покрывало лежит на кровати = The clean bedspread is lying on the bed

The basic meaning stays the same, but the emphasis shifts.

Because adjectives in Russian must agree with the noun they describe in:

• gender
• number
• case

The noun покрывало is:

• neuter
• singular
• nominative here

So the adjective must also be:

• neuter singular nominative → чистое

Compare:

• чистый стол = clean table (masculine)
• чистая комната = clean room (feminine)
• чистое покрывало = clean bedspread/blanket (neuter)

We know it from both meaning and grammar.

In this sentence:

• покрывало is in the nominative case
• the verb лежит is singular and matches it
• на кровати is a prepositional phrase telling us the location

So the structure is:

• На кровати = on the bed
• лежит = lies / is lying
• чистое покрывало = a clean bedspread

Even though the subject comes later in the sentence, it is still the subject.

Покрывало usually means bedspread, coverlet, or sometimes a cover/covering depending on context.

In this sentence, because it is on the bed, the most natural meaning is bedspread.

A learner might first think it means blanket, but Russian has other words too, for example:

• одеяло = blanket
• покрывало = bedspread/coverlet

So if the translation given to you says blanket, that may be acceptable in simple learning material, but bedspread is often more precise.

Because the subject покрывало is singular.

• покрывало = one bedspread
• therefore лежит = singular form

If the subject were plural, the verb would change:

• На кровати лежат чистые покрывала.
• There are clean bedspreads lying on the bed.

So:

• лежит = singular
• лежат = plural

Yes, but it would sound different.

• На кровати лежит чистое покрывало. = natural, everyday, visual
• На кровати находится чистое покрывало. = more formal, dry, or bookish

Лежит is better because it describes the object’s physical position.
Находится just means is located and is less vivid.

In ordinary speech, Russian usually prefers лежит here.

Russian has no articles, so the sentence itself does not directly mark the vs a.

Depending on context, чистое покрывало could mean:

• a clean bedspread
• the clean bedspread

In this word order, with the location first, it often feels a bit like introducing something:

• On the bed lies a clean bedspread

But context decides the exact interpretation.

A helpful stress pattern is:

• На крова́ти лежи́т чи́стое покрыва́ло.

Main stresses:

• крова́ти
• лежи́т
• чи́стое
• покрыва́ло

A rough pronunciation guide:

• na kra-VA-ti li-ZHEET CHEES-ta-ye pa-kri-VA-la

A couple of notes:

• г is not in this sentence, so no special issue there
• unstressed о is reduced in pronunciation, so покрывало does not sound like every o is fully pronounced as o
• чистое in careful speech is three syllables: чи-сто-е, though in faster speech it may sound more compressed

Yes. That is a very close literal translation.

A more natural English translation might be:

• There is a clean bedspread on the bed.
• A clean bedspread is lying on the bed.
• A clean bedspread lies on the bed.

All of these match the Russian well. The best English version depends on how natural or literal you want to be.
