Дочка попросила манго и киви к завтраку.

Both mean daughter, but дочка is the more affectionate, everyday form.

• дочь is the basic, more neutral word.
• дочка often sounds warmer, more family-like, and more natural in casual speech.

So this sentence has a slightly homier, more conversational tone because of дочка.

Попросила is the past tense of попросить, which means to ask for or to request.

It is feminine singular because the subject, дочка, is feminine.

Compare:

• дочка попросила = the daughter asked
• сын попросил = the son asked
• дети попросили = the children asked

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

• masculine: попросил
• feminine: попросила
• neuter: попросило
• plural: попросили

This is an aspect question.

• просить = imperfective
• попросить = perfective

Here, попросила shows a completed action: she asked once, and that act is viewed as a whole.

So:

• дочка просила can suggest she was asking, used to ask, or was in the process of asking
• дочка попросила means she made the request

In this sentence, the perfective verb fits naturally because it refers to one completed request.

Because манго and киви are normally indeclinable nouns in Russian. That means they usually keep the same form in different cases.

So even though they are the objects of the verb, they stay:

• манго
• киви

You do not normally change them the way you would change words like:

• яблоко → яблоко / яблока
• банан → банан / банана

With манго and киви, the form usually remains unchanged.

They are functioning as direct objects after попросила, so logically they are in the accusative case.

However, because манго and киви are indeclinable, their accusative form looks exactly like their dictionary form.

So grammatically:

• they are accusative objects
• but visually they do not change

That is why they look the same as nominative.

К завтраку means something like:

• for breakfast
• for the breakfast meal
• literally, toward breakfast or by breakfast time, depending on context

In this sentence, it means the daughter asked for mango and kiwi to have at breakfast.

This is a natural Russian way to express food intended for a meal.

Because the preposition к requires the dative case.

The noun is:

• dictionary form: завтрак
• dative singular: завтраку

So:

• к завтраку = for breakfast / by breakfast time

This is a common pattern:

• к обеду = for lunch / by lunchtime
• к ужину = for dinner / by dinnertime

Yes, but the nuance is a little different.

• на завтрак often means for breakfast in the sense of as the meal itself or to eat for breakfast
• к завтраку often means for breakfast / to go with breakfast / by breakfast time

In many everyday contexts, both can sound natural. But к завтраку can feel slightly more like for the breakfast table or to have with breakfast, while на завтрак more directly points to as breakfast food.

So Дочка попросила манго и киви к завтраку sounds very natural.

Russian usually does not use articles like a, an, or the, and it also often leaves words like some unstated when the meaning is clear from context.

So манго и киви can mean:

• mango and kiwi
• some mango and kiwi
• a mango and a kiwi
• mangoes and kiwis

The exact interpretation depends on context.

Russian is often less explicit than English about quantity unless quantity really matters.

It can be somewhat ambiguous without context.

Depending on the situation, it could mean:

• one mango and one kiwi fruit
• some mango and kiwi
• mango and kiwi as kinds of fruit

Because Russian often leaves number and article-like distinctions unspoken, you rely on context.

If a speaker wanted to be more specific, they could say:

• одно манго и один киви = one mango and one kiwi
• манго и киви = more general or context-dependent

Russian word order is more flexible than English word order.

The sentence:

• Дочка попросила манго и киви к завтраку

is the neutral, natural order:

1. subject
2. verb
3. requested items
4. time/meal phrase

You could rearrange parts of it for emphasis, for example:

• К завтраку дочка попросила манго и киви.
• Манго и киви дочка попросила к завтраку.

These alternatives are grammatical, but they shift emphasis. The original version sounds like the most straightforward way to say it.

A rough pronunciation guide:

Дочка попросила манго и киви к завтраку
DOCH-ka pa-pra-SEE-la MAN-ga ee KEE-vee k zaF-tra-koo

A few notes:

• дочка: stress on the first syllable — ДО-чка
• попросила: stress on -си- — попроСИла
• манго: stress on the first syllable — МАНго
• киви: stress on the first syllable — КИви
• завтраку: stress on the first syllable — ЗАвтраку

Also, in connected speech, unstressed о often sounds more like a.

Yes, if the subject is clear from context.

Russian often drops pronouns, and sometimes even a noun subject can be omitted if everyone already knows who is being talked about.

For example:

• Попросила манго и киви к завтраку.
  = She asked for mango and kiwi for breakfast.

But with дочка included, the sentence is clearer and more self-contained.
