После работы моя сестра распускает волосы и надевает тёплый халат.

Because после requires the genitive case.

• работа = nominative singular
• работы = genitive singular

So:

• после работы = after work

This is a very common pattern in Russian:

• после урока = after the lesson
• после обеда = after lunch
• после фильма = after the film

So the learner should remember: после + genitive.

Because моя сестра is the subject of the sentence, so it is in the nominative case.

• моя сестра = my sister (subject form)
• мою сестру = my sister (object form)

Here, the sister is the person doing the actions:

• she lets her hair down
• she puts on a warm robe

So nominative is required:

• моя сестра распускает...
• моя сестра надевает...

If she were the object, then you would use мою сестру.

In Russian, the present tense is often used to describe habitual, regular, or typical actions.

So this sentence does not have to mean only right now. It can also mean:

• After work, my sister lets her hair down and puts on a warm robe.
• In other words: this is what she usually does.

This is very natural in Russian. English often does something similar with the simple present for routines:

• She comes home, makes tea, and reads.

So распускает and надевает are present-tense forms used for a repeated action.

Here распускать волосы means to let one’s hair down or to loosen/unbind the hair.

It is used when someone had their hair tied up, braided, pinned, etc., and then releases it.

Important point: распускать has different meanings in other contexts, but with волосы it specifically means something like:

• to let the hair down
• to undo the hair

So in this sentence, it is not about spreading or dissolving in some abstract sense; it is the normal expression for hair.

Russian commonly uses волосы in the plural when talking about the hair on someone’s head.

So:

• волосы = hair
• literally, it is grammatically plural

This is just a normal difference between Russian and English.

Examples:

• длинные волосы = long hair
• мыть волосы = to wash one’s hair
• распустить волосы = to let one’s hair down

The singular волос usually means a single hair.

It is in the accusative plural, because it is the direct object of распускает.

However, for inanimate plural nouns, the accusative often looks exactly like the nominative.

So here:

• nominative plural: волосы
• accusative plural: волосы

That is why the form does not visibly change.

This is a very common question.

In standard Russian:

• надевать / надеть = to put on something
• одевать / одеть = to dress someone

So:

• она надевает халат = she puts on a robe
• она одевает ребёнка = she dresses the child

A useful shortcut:

• надеть что? = put on what?
• одеть кого? = dress whom?

Since халат is the item being put on, надевает is the correct verb.

It is in the accusative singular, because it is the direct object of надевает.

But халат is:

• masculine
• inanimate

For many masculine inanimate nouns, the accusative singular looks the same as the nominative singular.

So:

• nominative: халат
• accusative: халат

That is why there is no visible change.

Because the adjective must agree with the noun in:

• gender
• number
• case

Here халат is:

• masculine
• singular
• accusative (same form as nominative because it is inanimate)

So the adjective must match that pattern:

• тёплый халат

Compare:

• тёплая кофта = a warm sweater/jacket
• тёплое пальто = a warm coat
• тёплые носки = warm socks

Тёплый is pronounced with ё: roughly TYOP-lyy.

In many Russian texts, ё is often written as е, so you may also see:

• теплый халат

But the pronunciation and the standard dictionary form are still тёплый.

This happens with many words in Russian. Learners should be aware that:

• ё may be omitted in writing
• but it still matters for pronunciation and sometimes for understanding

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

So Russian simply says:

• сестра
• волосы
• халат

Context tells you whether English should use:

• a
• the
• or no article

For example, тёплый халат could be translated as:

• a warm robe
• the warm robe

depending on context. In this sentence, English naturally uses a warm robe.

Yes. Russian word order is relatively flexible, because the cases already show the grammatical roles.

The neutral order here is:

• После работы моя сестра распускает волосы и надевает тёплый халат.

But other orders are possible, for example:

• Моя сестра после работы распускает волосы и надевает тёплый халат.

The meaning stays basically the same, but the emphasis can shift slightly.

The original version is very natural because После работы sets the scene first: After work...

Usually после работы means after work in a general everyday sense, often close to after coming home from work or when work is finished.

Because Russian has no articles, it does not explicitly say the work or work in general. Context decides it.

In this kind of sentence, the natural understanding is the routine meaning:

• after she finishes work
• after she gets home from work

So it works very much like English after work.

The verbs распускает and надевает are imperfective because the sentence describes a habitual routine, not one single completed event.

In Russian:

• imperfective is often used for repeated, usual, or ongoing actions
• perfective is often used for a one-time completed action

Here the idea is:

• after work, she typically does these things

So imperfective is the natural choice.

If you were describing one completed occasion, Russian might use perfective forms in a different structure, for example in the past tense.
