daikon wo tiisaku kitte kara, suupu ni iremasu.

を marks the direct object — the thing being acted on.

Here, 大根を means the daikon is what you cut, and it is also what you later put into the soup.

So in this sentence:

• 大根を切って = cut the daikon
• 大根をスープに入れます = put the daikon into the soup

Japanese often states the object once and then continues with more than one action involving it.

小さい is an い-adjective, meaning small.

When an い-adjective modifies a verb, it changes to the -く form:

• 小さい = small
• 小さく = in a small way / small

So:

• 小さく切る = cut into small pieces

This is similar to how English sometimes uses an adverb, though the match is not perfect. A natural English translation is cut it small or cut it into small pieces.

Because the sentence is connecting actions.

In Japanese, when one action happens before another, the earlier verb is often put into the て-form:

• 切る → 切って

So:

• 切ってから = after cutting

Only the last main verb in the sentence usually carries the full tense/politeness marking, which is why the sentence ends with 入れます.

〜てから means after doing....

So:

• 切ってから = after cutting

The pattern is:

• Verb in て-form + から

It shows that one action happens first, and the next action happens after that.

Here the order is:

1. cut the daikon small
2. put it into the soup

It emphasizes sequence very clearly.

This is a very important difference.

• 切ってから = after cutting
• 切ったから = because I cut / since I cut

So:

• 大根を小さく切ってから、スープに入れます。
  = After cutting the daikon into small pieces, I put it in the soup.

But:

• 大根を小さく切ったから、スープに入れます。
  sounds like Because I cut the daikon small, I’ll put it in the soup, which is a different meaning.

So てから is about time/order, while たから is usually about reason.

With 入れる, に often marks the place or target that something goes into.

So:

• スープに入れます = put it into the soup

Here:

• 大根 = the thing being put in
• スープに = the destination/container

Compare:

• 大根をスープに入れます = put the daikon into the soup
• スープを入れます = put in / pour the soup

So に helps show that the soup is the place something enters, not the thing being acted on directly.

These are a transitive/intransitive pair:

• 入れます = put something in
• 入ります = go in / enter

In this sentence, someone is actively putting the daikon into the soup, so 入れます is used.

Compare:

• 大根をスープに入れます。
  = I put the daikon into the soup.

• 大根がスープに入ります。
  = The daikon goes into the soup.

The second version focuses more on the daikon entering, not on who puts it there.

In Japanese, when verbs are linked together, the earlier verb usually appears in a connecting form, and the final verb shows the sentence’s tense and politeness.

So:

• 切って is the connecting form
• 入れます is the final polite verb

This is very normal Japanese structure.

You could think of it like:

• Cut it small, and then put it in the soup

The sentence’s main ending is carried by 入れます.

Yes, the subject is omitted.

Japanese often leaves out the subject when it is obvious from context. In a cooking instruction like this, the implied subject could be:

• you
• I
• we
• the cook
• or just a general instruction, like in a recipe

So the sentence does not need to say あなたは or 私は.

This is extremely common in Japanese.

Yes, more or less.

Literally, 小さく切る is something like cut small. In natural English, that usually becomes:

• cut into small pieces
• cut finely
• cut it small

Japanese often expresses the result of the action this way:

• 細かく切る = cut finely
• 薄く切る = cut thin
• 短く切る = cut short

So 小さく describes the state the daikon should have after cutting.

Normally, Japanese is written without spaces.

So the standard written sentence would be:

大根を小さく切ってから、スープに入れます。

The spaces are usually added in beginner materials to make the sentence easier to read and to show word boundaries.

The comma 、 is normal Japanese punctuation, but the spaces are mainly a learning aid.
