В корзине для белья лежит капсула для стирки.

Because after в meaning in, Russian usually uses the prepositional case to show location.

• корзина = basket
• в корзине = in the basket

So:

• nominative: корзина
• prepositional: в корзине

This is one of the most common patterns in Russian:

• в доме = in the house
• в комнате = in the room
• в корзине = in the basket

If the phrase meant motion into the basket, Russian would usually use the accusative instead:

• в корзину = into the basket

Russian often prefers a position verb like лежать (to lie), стоять (to stand), or висеть (to hang) instead of a plain there is structure.

So лежит literally means is lying or lies.

• В корзине лежит капсула = A pod is lying in the basket / There is a pod in the basket.

This sounds natural in Russian because the object is understood as being in a horizontal or resting position.

Using есть here would usually sound unnatural. Russian does not use есть the same way English uses there is in ordinary location statements.

Because the subject is капсула, which is singular.

• капсула = capsule / pod
• лежит = lies / is lying (singular)
• лежат = lie / are lying (plural)

Compare:

• В корзине лежит капсула. = There is one pod in the basket.
• В корзине лежат капсулы. = There are pods in the basket.

The verb agrees with the grammatical subject in number.

Because для requires the genitive case.

• для = for
• бельё = laundry / linen
• genitive of бельё = белья

So:

• корзина для белья = basket for laundry / laundry basket

This is a very common pattern:

• чашка для чая = cup for tea
• щётка для обуви = brush for shoes
• машина для стирки = machine for washing

In this sentence, корзина для белья is a fixed noun phrase meaning laundry basket.

Because after для, Russian uses a noun, not an infinitive verb.

• стирать = to wash
• стирка = washing, laundry, wash cycle
• genitive after для: стирки

So:

• капсула для стирки = capsule/pod for washing

English often says for washing with an -ing form, but Russian usually uses a noun here:

• для работы = for work
• для отдыха = for rest
• для стирки = for washing / for laundry

So для стирки is the natural Russian way to say this.

It means a laundry capsule/pod, like a detergent pod used in a washing machine.

Word by word:

• капсула = capsule, pod
• для стирки = for washing / for laundry

So the whole phrase is a normal descriptive noun phrase: a washing capsule, more naturally in English a laundry pod or detergent pod depending on context.

Russian word order is flexible, and the beginning of the sentence often gives the setting or location first.

So:

• В корзине для белья лежит капсула для стирки.
  = In the laundry basket, there is a laundry pod.

This sounds natural because it introduces the place first and then tells you what is there.

You could also say:

• Капсула для стирки лежит в корзине для белья.

That also means the same thing, but it gives slightly more focus to the pod rather than the location.

In many cases, Russian places old/background information first and newer/more important information later.

No—Russian has no articles.

So Russian does not directly mark the difference between:

• a capsule
• the capsule

The exact meaning depends on context, word order, and the situation.

In this sentence, English could translate it as either:

• There is a laundry pod in the laundry basket
• The laundry pod is in the laundry basket

But because the sentence starts with the location and introduces капсула afterward, it often feels more like a pod is being introduced.

Капсула is in the nominative case, because it is the subject of the sentence.

Even though it comes after the location phrase, it is still the thing that лежит.

So the structure is:

• В корзине для белья = location phrase
• лежит = verb
• капсула для стирки = subject

This is a good reminder that in Russian, the subject does not always come first.

Literally, бельё can mean linen, underwear, or laundry depending on context. But in корзина для белья, the natural meaning is laundry.

So:

• корзина для белья = laundry basket

A very literal translation like basket for linen is possible from the dictionary meaning, but it would not be the best everyday English translation here.

The main stresses are:

• в корзИне
• для бельЯ
• лежИт
• капсУла
• для стИрки

Stress is important in Russian because it is not always predictable. For example:

• бельё has stress on the final -ё
• белья keeps the stress near the end: бельЯ

If you are learning pronunciation, it is worth memorizing words together with stress from the beginning.

Yes. Лежать is very commonly used for objects that are simply resting somewhere, especially if they are not upright.

Russian often chooses among these verbs:

• лежать = lie, be lying
• стоять = stand, be standing
• висеть = hang, be hanging

A detergent pod in a basket would naturally лежать.

For example:

• На столе лежит книга. = A book is lying on the table.
• На полке стоит бутылка. = A bottle is standing on the shelf.
• На стене висит картина. = A picture is hanging on the wall.

So this is not strange at all—it is standard Russian usage.
