suupaa de kyabetu to kyuuri wo katte, sarada wo tukurimasita.

で marks the place where an action happens.

So in スーパーで, it means at the supermarket or in the supermarket as the location of the buying action.

A useful comparison:

• で = where an action takes place
• に = where something exists, goes, or ends up

Here, since the speaker is buying something at the supermarket, で is the natural particle.

Because there are two different verbs, and each verb has its own direct object.

• キャベツときゅうりを買って
  = bought cabbage and cucumbers
• サラダを作りました
  = made salad

So:

• を marks what was bought
• another を marks what was made

This is completely normal in Japanese when multiple actions are connected in one sentence.

Here, と means and.

So:

• キャベツときゅうり = cabbage and cucumbers

This と is used to list nouns in a fairly complete, straightforward way.

It suggests a clear list of the items involved. In this sentence, the speaker bought both cabbage and cucumbers.

買って is the て-form of 買う.

The て-form has many uses, and one very common use is to connect actions. In this sentence, it links:

• bought cabbage and cucumbers
• made salad

So the structure is basically:

• Xを買って、Yを作りました
• bought X, and made Y

You can think of 買って here as meaning something like:

• bought ... and then
• having bought ...

It connects the first action to the second.

Usually, yes. In this sentence, the natural interpretation is:

1. bought cabbage and cucumbers
2. made salad

When the て-form connects actions like this, it often suggests sequence, especially when that order makes sense logically.

So this sentence is understood as I bought cabbage and cucumbers at the supermarket, then made a salad.

The final verb in a sentence usually carries the tense and politeness for the whole sentence.

Here:

• 買って connects the first action
• 作りました finishes the sentence in polite past form

So the sentence ends with the fully conjugated verb:

• 作りました = made

This is a very common pattern:

• Verb-て、Verbました
• do A, then did B

作りました is the polite past form of 作る (to make).

Breakdown:

• dictionary form: 作る
• polite non-past: 作ります
• polite past: 作りました

So it means made in a polite style.

Because the last verb is in the past, the sentence as a whole is understood as talking about past actions.

Yes, the subject is omitted.

Japanese often leaves out subjects when they are understood from context. So even though English needs I, Japanese does not have to say it.

This sentence could naturally mean:

• I bought cabbage and cucumbers at the supermarket and made a salad
• or, depending on context, we bought ... and made ...

If the speaker wanted to be explicit, they could say 私は, but in everyday Japanese that is often unnecessary.

Japanese uses multiple writing systems together.

In this sentence:

• スーパー = katakana
• キャベツ = katakana
• サラダ = katakana
• きゅうり = hiragana
• 買って、作りました = kanji + hiragana
• particles like で、と、を = hiragana

Why?

• Katakana is often used for loanwords and many food names
• Hiragana is used for grammar and some native words
• Kanji is used for many verb stems and content words

A few notes:

• スーパー is from supermarket
• サラダ is from salad
• キャベツ is also a loanword
• きゅうり is often written in hiragana, though kanji exists

The comma shows a pause and helps separate the two actions.

• 買って、サラダを作りました。

It is not always strictly required, but it is very common in writing because it makes the sentence easier to read.

It works a bit like a natural pause in speech:

• bought cabbage and cucumbers at the supermarket, and made salad

No, not here.

In this sentence, と is clearly the noun-listing and:

• キャベツときゅうり = cabbage and cucumbers

Japanese と can sometimes mean with, but that usually depends on context and sentence structure. Here, since it is placed between two nouns that are both the object of 買う, the meaning is simply and.

Yes, it literally means made salad or made a salad.

Japanese does not have articles like a, an, or the, so the language often leaves that kind of detail unstated.

Depending on context, サラダを作りました could be understood as:

• made a salad
• made the salad
• made salad

In English, made a salad is usually the most natural translation here.

It is in polite Japanese.

The clue is the ending:

• 作りました

The -ました ending is polite.

If it were casual, it would be:

• スーパーでキャベツときゅうりを買って、サラダを作った。

So this sentence is appropriate for normal polite conversation, writing, or textbook style.

Yes, that is the natural implication, even though Japanese does not explicitly say using them.

The sentence says:

• bought cabbage and cucumbers
• made salad

Because those actions are connected, listeners naturally understand that the bought ingredients were used to make the salad.

If someone wanted to be more explicit, they could say something like キャベツときゅうりでサラダを作りました for made a salad with cabbage and cucumbers, but the original sentence already strongly suggests that connection.
