Мама долго утешала дочку после неудачного выступления.

Because дочку is the accusative singular form, and it is the direct object of утешала.

• кто? что? → дочка = nominative
• кого? что? → дочку = accusative

The verb утешать takes a direct object: утешать кого? = to comfort whom?

So:

• Мама = subject
• утешала = verb
• дочку = object

Дочка is a very common everyday word for daughter. It often sounds warmer, more personal, or more family-oriented than дочь.

• дочь = more neutral, sometimes more formal or bookish
• дочка = natural in ordinary speech, often affectionate

So Мама долго утешала дочку... sounds very natural in a family context.

In the past tense, Russian verbs agree with the subject in gender and number.

The subject here is мама, which is feminine, so the verb must also be feminine:

• masculine: утешал
• feminine: утешала
• neuter: утешало
• plural: утешали

So Мама утешала = Mother was comforting / comforted.

This is a question of aspect.

• утешала = imperfective
• утешила = perfective

Here, утешала is used because the sentence focuses on the process and duration of comforting, especially with долго = for a long time.

So:

• Мама долго утешала дочку = The mother comforted her daughter for a long time / was comforting her for a long time
• Мама утешила дочку = The mother managed to comfort her daughter, with more focus on the result

Because долго highlights duration, the imperfective утешала fits very naturally.

Долго means for a long time, for quite a while, or a long time.

It describes the duration of the action:

• утешала = was comforting / comforted
• долго утешала = comforted for a long time

It often goes well with imperfective verbs because they describe ongoing or repeated action.

Because the preposition после always requires the genitive case.

So:

• выступление → выступления
• неудачное → неудачного

The adjective must agree with the noun in case, gender, and number.

Breakdown:

• после
  • genitive
• неудачного = genitive singular of неудачный
• выступления = genitive singular of выступление

So the whole phrase means after an unsuccessful performance/speech/presentation.

Выступление is a broad word. Depending on context, it can mean:

• performance
• speech
• presentation
• public appearance

So in this sentence, it could refer to a child performing on stage, giving a speech, taking part in a recital, and so on.

The exact English translation depends on the situation, but the Russian word itself is quite flexible.

Неудачный means something like:

• unsuccessful
• that went badly
• unfortunate
• disappointing

It does not necessarily mean the performance was terrible in every possible way. It often suggests that it did not go as hoped.

So после неудачного выступления sounds like after a performance that did not go well.

No. Russian word order is relatively flexible because case endings show grammatical roles.

The neutral order here is:

• Мама — subject
• долго утешала — verb phrase
• дочку — object
• после неудачного выступления — time/context phrase

But other orders are also possible, with different emphasis:

• После неудачного выступления мама долго утешала дочку.
  Emphasizes the situation first.
• Дочку мама долго утешала после неудачного выступления.
  Emphasizes the daughter.
• Мама дочку долго утешала...
  Slightly stronger focus on дочку.

The original version is natural and neutral.

Russian often leaves out possessive words when the relationship is obvious from context.

Here, мама and дочка naturally suggest a family relationship, so Russian does not need to say her daughter explicitly.

If you wanted to make it explicit, Russian would usually prefer:

• Мама долго утешала свою дочку... = Mother comforted her own daughter...

Using её дочку would usually mean someone else’s daughter, not the subject’s own daughter.

So the version without a possessive is very natural.

Russian has no articles.

So a noun like мама, дочка, or выступление can mean:

• a mother / the mother
• a daughter / the daughter
• a performance / the performance

Context tells you which meaning is intended.

In this sentence, English normally uses the mother, her daughter, and the/an unsuccessful performance, but Russian does not mark that grammatically.

A natural stress pattern is:

Ма́ма до́лго утеша́ла до́чку по́сле неуда́чного выступле́ния.

A few useful stress points:

• Ма́ма
• до́лго
• утеша́ла
• до́чку
• по́сле
• неуда́чного
• выступле́ния

Stress is important in Russian because it is not always predictable, so it is worth learning words together with their stress.

Yes, indirectly.

Literally, после неудачного выступления means after the unsuccessful performance, so it is a time phrase. But in context, it also strongly suggests why the mother was comforting her daughter.

So the phrase gives both:

• when it happened
• and, by implication, what caused the distress

Russian often does this without needing a separate word like because of.
