Each の links one noun to another, a bit like of or an apostrophe-s in English.

• スーパーの果物 = the supermarket’s fruit / fruit at the supermarket
• 果物の売り場 = the fruit sales area / the place where fruit is sold

So the whole phrase スーパーの果物の売り場 means the fruit section of the supermarket.

Japanese often chains nouns this way, so multiple の in one phrase is very normal.

売り場 means sales floor, counter, department, or section where something is sold.

In this sentence, 果物の売り場 is the fruit section.

It is made from:

• 売る = to sell
• 場 = place

So literally it is something like the place for selling.

で marks the place where an action happens.

Here, the action is 見つけたら = if/when I find.

So:

• 売り場で見つけたら = if I find them in the fruit section

Compare:

• で = where an action happens
• に = destination, existence, or specific point in time, depending on context

Because finding happens at that location, で is the correct particle.

赤い is an i-adjective, and i-adjectives directly modify nouns.

So:

• 赤いりんご = red apples

This is the normal way to say it in Japanese: adjective first, noun second.

You do not need a word like な here, because 赤い is already an i-adjective.

を marks the direct object of the verb.

In this part:

• 赤いりんごを見つけたら = if/when I find red apples

The thing being found is red apples, so りんご takes を.

見つけたら is the たら conditional form of 見つける.

• dictionary form: 見つける = to find
• past form: 見つけた = found
• conditional: 見つけたら = if/when I find; if/when I found

In this sentence, it means:

• if I find red apples
• or more naturally in context, if I happen to find red apples

The たら form is very common for conditions.

It can feel like either, depending on context.

In this sentence, 見つけたら suggests:

• if I find them if the result is uncertain
• when I find them if the speaker expects it may happen

English often forces you to choose one, but Japanese たら can leave that a little softer or more open.

Japanese is usually a subject-object-verb language, so the main verb often comes at the end of the clause or sentence.

Here the structure is roughly:

• [if I find red apples in the fruit section]
• [for my mother]
• [two]
• [will buy]

So 買います naturally comes at the end.

Both are grammatically correct, but they differ in politeness.

• 買う = plain form
• 買います = polite form

This sentence uses polite style, so 買います matches that.

Also, even though the first verb is 見つけたら, the main verb does not have to be plain just because the conditional is plain-looking. The sentence can still end politely.

When talking about your own mother to someone else, Japanese usually uses 母.

• 母 = my mother / one’s own mother, in a more neutral or humble way
• お母さん = mother, but often used when addressing your mother directly or referring to someone else’s mother more politely

So in this sentence, 母のために is the natural choice for for my mother.

ために means for the sake of, for, or on behalf of.

So:

• 母のために = for my mother

This shows the purpose or beneficiary of the action.

The sentence means the speaker will buy the apples so that the mother can have them, or for her benefit.

Using のために makes the idea of for someone’s benefit very clear.

• 母に買います could sound like I will buy (something) for my mother, but it can also feel incomplete without more context.
• 母のために買います clearly means I will buy them for my mother / for my mother’s sake.

So のために is slightly more explicit and purposeful.

二つ is the native Japanese general counter for two things.

Apples can be counted with:

• 二つ = two items, general and very common
• 二個 = two pieces/items, also possible for apples

In everyday Japanese, 二つ sounds very natural here.

So:

• 二つ買います = I will buy two

Actually, Japanese often does say りんごを二つ買います, and that is also correct.

In this sentence, 赤いりんごを already appeared earlier, so 二つ買います is enough. The object is understood from context.

Japanese often leaves out words that are already clear.

Yes. Japanese counters are fairly flexible.

These are all natural:

• 赤いりんごを二つ買います
• 二つ買います
• 赤いりんご二つを買います (less common in everyday speech, but possible in some contexts)

In your sentence, placing 二つ before 買います sounds very natural.

The subject is omitted, which is extremely common in Japanese.

From the verb ending and context, we understand it as something like:

• I will buy two
• I find red apples

So the full English idea is If I find red apples in the fruit section of the supermarket, I will buy two for my mother, even though Japanese does not say I explicitly.

It is talking about apples in general first, then specifically says two will be bought.

Japanese nouns usually do not show singular vs. plural the way English nouns do.

So:

• りんご can mean apple or apples, depending on context

Because the sentence later says 二つ, we know the speaker means buying two apples.

Yes, depending on the context.

• if I find red apples emphasizes possibility
• when I find red apples sounds more expected or planned

Japanese 見つけたら can cover both ideas, so either translation may work.

The comma separates the conditional clause from the main action.

• 赤いりんごを見つけたら、母のために二つ買います。

This makes the sentence easier to read, just like in English:

• If I find red apples, I’ll buy two for my mother.

Japanese commas are often flexible, but this is a very natural place to put one.

Yes. スーパーで would mean at the supermarket, which is simpler and still correct in many situations.

But スーパーの果物の売り場で is more specific:

• スーパーで = at the supermarket
• スーパーの果物の売り場で = in the fruit section of the supermarket

So the longer version gives more detail about where the apples are being found.

Yes. スーパー is a very common katakana word borrowed from supermarket.

It usually means:

• supermarket
• sometimes just grocery store

Katakana is often used for loanwords like this.
