Из абрикосов мама сварила компот, а часть фруктов положила в морозилку.

Из usually means from, out of, made from and it requires the genitive case.

So:

• абрикосы = apricots
• из абрикосов = from apricots / out of apricots

In this sentence, Из абрикосов мама сварила компот means that the compote was made from apricots.

By contrast, с абрикосами usually means with apricots, not made from apricots. That would express accompaniment or inclusion, not the source material in the same way.

Because the preposition из requires the genitive case, and the base noun is plural:

• nominative singular: абрикос
• nominative plural: абрикосы
• genitive plural: абрикосов

So из абрикосов is the normal form after из.

Russian word order is much more flexible than English word order. The sentence could also be arranged differently, for example:

• Мама сварила компот из абрикосов.

That is probably the most neutral order in many contexts.

Starting with Из абрикосов puts emphasis on the ingredient or source: As for the apricots, mom made compote from them...

So the chosen word order helps guide the listener’s attention. It is not grammatically strange; it is a matter of focus and style.

The verb сварить literally means to boil / to cook by boiling, and in this context it means to make by boiling, so сварила компот means made/cooked compote.

Compote is a drink prepared by boiling fruit in water, so сварить is the natural verb here.

This verb is also perfective, which means the action is seen as completed: she made it, the result exists.

Its imperfective partner is варить:

• мама варила компот = mom was making / used to make compote
• мама сварила компот = mom made compote, finished it

Because the subject is мама, which is grammatically feminine.

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

• masculine: сварил
• feminine: сварила
• neuter: сварило
• plural: сварили

So:

• мама сварила
• мама положила

Even though мама refers to a person, grammatically it behaves as a feminine noun, so the verbs take feminine past forms.

Here компот is the direct object of сварила.

The noun компот is masculine and inanimate. For masculine inanimate nouns, the accusative singular is the same as the nominative singular:

• nominative: компот
• accusative: компот

So even though it is functioning as the object, its form does not change.

After words that mean part, amount, quantity, group, Russian often uses the genitive for the thing being measured or divided.

So:

• часть = part
• часть фруктов = part of the fruit / some of the fruit

This is similar to:

• стакан воды = a glass of water
• много людей = many people
• кусок хлеба = a piece of bread

So фруктов is genitive plural because it depends on часть.

Russian often avoids repetition when the meaning is already clear.

Since the first half already mentions абрикосы, the phrase часть фруктов is understood as part of that fruit, meaning the apricots already mentioned.

Using фруктов sounds natural and slightly more general. It is similar to English saying:

• Mom made compote from the apricots, and put some of the fruit in the freezer.

You could also say часть абрикосов, but часть фруктов is perfectly natural here.

The object is expressed by часть фруктов, which comes before the verb:

• а часть фруктов положила в морозилку

Literally: and [she] put part of the fruit into the freezer

Russian often omits a repeated subject when it is obvious, but here the object is not omitted; it is simply placed before the verb.

The subject мама is understood from the first clause, so Russian does not need to repeat it.

Because this sentence describes motion into the freezer, not location inside it.

With в, Russian uses:

• accusative for direction/motion: into
• prepositional for location: in

So:

• положила в морозилку = put into the freezer
• лежит в морозилке = is in the freezer

Here the action is movement from outside to inside, so морозилку is accusative.

А can sometimes be translated as and, but it often has a slight sense of contrast, switch of focus, or meanwhile.

Here it links two related actions:

• she made compote from the apricots,
• and she put some of the fruit in the freezer.

So а is not a strong contrast like but, but it does set up a second, distinct action. In English, depending on context, you might translate it as:

• and
• while
• whereas
• and as for the rest...

It gives the sentence a natural narrative flow.

Yes, absolutely. That version is also correct.

Both versions are grammatical:

• Из абрикосов мама сварила компот...
• Мама сварила из абрикосов компот...

The difference is mainly in emphasis:

• Из абрикосов... highlights the ingredient first.
• Мама сварила... is more neutral and straightforward.

Russian word order often reflects what the speaker wants to emphasize, not just strict grammatical structure.

Russian has no articles, so nouns appear without words like a, an, or the.

So компот can mean:

• compote
• a compote
• the compote

The exact interpretation depends on context.

In this sentence, English would usually say compote without an article if speaking generally about the dish/drink, or some compote depending on context. Russian simply leaves that distinction to the situation and word order rather than using articles.
