На завтрак я люблю мюсли с йогуртом и кусочками кураги.

На завтрак means for breakfast or more literally as breakfast.

Russian often uses на + accusative for meals:

• на завтрак — for breakfast
• на обед — for lunch
• на ужин — for dinner

So На завтрак я люблю... is a very natural way to say For breakfast, I like...

It does not mean movement here, even though на often means onto/to in other contexts.

Because after на in this expression, Russian uses the accusative case.

The base noun is завтрак. For an inanimate masculine noun like this, the accusative singular looks the same as the nominative singular:

• nominative: завтрак
• accusative: завтрак

So:

• на завтрак — for breakfast

If it were a different structure, you might see other cases, but in this fixed everyday expression, на завтрак is the normal form.

Yes, you could.

Russian word order is more flexible than English word order.
These are all possible, with slightly different emphasis:

• На завтрак я люблю мюсли... — emphasizes for breakfast
• Я люблю на завтрак мюсли... — emphasizes I like
• Мюсли с йогуртом... я люблю на завтрак — emphasizes the food itself

The version in your sentence is very natural because it sets the context first: As for breakfast...

Both can be correct, but they are used a bit differently.

• я люблю = I like / I love / I enjoy
• мне нравится = I like in the sense of it pleases me

In this sentence, я люблю sounds very natural for talking about food you like to eat regularly:

• Я люблю мюсли — I like muesli

You could also say:

• Мне нравятся мюсли — I like muesli

But notice the grammar changes with нравиться:

• мне нравится йогурт
• мне нравятся мюсли

So я люблю is simpler and very common here.

Yes, but usually Russian leaves out есть here.

• Я люблю мюсли... already strongly implies I like eating muesli
• Я люблю есть мюсли... is grammatical, but it can sound slightly more explicit than necessary

Russian often omits есть when the meaning is obvious, especially with foods:

• Я люблю кофе — I like coffee
• Я люблю пиццу — I like pizza

So in your sentence, leaving out есть is the most natural choice.

It is in the accusative case, because it is the direct object of люблю.

You like what?

• мюсли

However, мюсли is one of those words that usually does not change its form, so it looks the same here.

You can think of it like this:

• nominative: мюсли
• accusative: мюсли

Also, мюсли is normally treated as an indeclinable noun in modern Russian.

It is usually treated as a plural-type food word, similar in idea to English muesli being a mass noun.

In practice, learners mostly need to know two things:

1. мюсли usually does not change form
2. it often behaves like a plural noun in agreement

For example:

• вкусные мюсли — tasty muesli
• эти мюсли — this/these muesli

That said, usage can vary a little in everyday speech, but for learning purposes, treating мюсли as an indeclinable plural noun is a good approach.

Because с meaning with requires the instrumental case.

So:

• йогурт → с йогуртом
• чай → с чаем
• молоко → с молоком

In your sentence:

• с йогуртом = with yogurt

The ending -ом is the regular instrumental singular ending for many masculine and neuter nouns.

This part has two layers of grammar:

1. Why с кусочками?

Again, с = with, so it takes the instrumental case.

The base word is кусочки = pieces / little pieces.
Instrumental plural:

• кусочки → кусочками

So:

• с кусочками = with pieces

2. Why кураги?

Because курага depends on кусочки.

This is the pattern:

• pieces of what? → of dried apricot

Russian expresses that with the genitive case:

• кусочки кураги — pieces of dried apricot

So the full phrase is:

• с кусочками кураги — with pieces of dried apricot

Курага is dried apricot.

More specifically, it usually refers to dried apricot as a food product, not just any adjective+noun combination like dry apricot.

So:

• кусочки кураги = pieces of dried apricot

It is a common food word in Russian, especially in contexts like breakfast, snacks, baking, or porridge.

Because one preposition can apply to both items in a list.

So:

• с йогуртом и кусочками кураги means
• with yogurt and pieces of dried apricot

Russian could repeat the preposition, but usually does not need to:

• с йогуртом и с кусочками кураги — also possible, but more emphatic or stylistically heavier

The version with one с is the normal, natural one.

It is plural because the speaker means pieces/chunks rather than one piece.

• с кусочками кураги — with pieces of dried apricot
• с кусочком кураги — with a piece of dried apricot

Both are grammatical, but they mean different things.
For breakfast food like muesli, plural кусочками sounds more natural, because there are usually several pieces mixed in.

It can mean both, depending on context.

На завтрак я люблю мюсли с йогуртом и кусочками кураги can mean:

• For breakfast, I like muesli with yogurt and pieces of dried apricot
• in other words, a general preference
• and often also something the speaker commonly eats

Russian люблю often covers both I like and I enjoy having in a general sense. If the speaker wanted to emphasize a repeated habit very strongly, they might use other wording too, but this sentence is perfectly natural as it is.

Usually for breakfast is the best translation here.

• На завтрак я люблю... = For breakfast, I like...

At breakfast in English sounds more like the time or situation of being at the breakfast table, while the Russian phrase here is about what someone has as breakfast.

So although meanings can overlap, for breakfast is the most accurate and natural match.
