를 is the object marker. It marks 딸기 as the thing being acted on.

In this sentence, the strawberries are:

• washed
• then placed into a bowl

So 딸기를 means the strawberries as the direct object.

Also, Korean nouns often do not have to show singular/plural clearly. So 딸기 can mean:

• a strawberry
• strawberries

Context tells you which one is meant. In a sentence like this, strawberries is the natural interpretation.

Here, 에 marks the destination or place something goes into.

With 담다 (to put in / place into / contain), Korean often uses this pattern:

• thing + 을/를
• container/place + 에
• 담다

So:

• 딸기를 = the strawberries
• 그릇에 = into the bowl

That is why 그릇에 담다 means to put something into a bowl/container.

If you used 그릇을, it would sound like the bowl itself is the object being acted on, which is not what this sentence means.

씻어서 comes from 씻다 (to wash) plus -어서, a connective ending.

In this sentence, -어서 links the two actions:

• wash the strawberries
• put them in a bowl

So 씻어서 means something like:

• after washing
• having washed
• wash and then

Here it mainly shows that the first action happens before the second one.

Both can connect actions, so both 씻어서 and 씻고 may be possible in similar contexts.

The difference is nuance:

• -고 is a more neutral and then
• -아서/어서 often feels more closely connected, as if the first action leads into or prepares for the second

So 씻어서 그릇에 담아 두었어요 feels like:

• the strawberries were washed,
• and as part of that preparation, they were put into the bowl.

It sounds very natural because washing is a step that sets up the next action.

This is one of the most important parts of the sentence.

담아 두었어요 = 담다 + 아/어 두다 + past polite ending

아/어 두다

This grammar means:

• do something
• and leave it that way
• often for later use, convenience, or preparation

So 담아 두었어요 is not just put it in a bowl. It suggests:

• it was placed in the bowl
• and left there ready/prepared

That gives the sentence a nuance like:

• I washed the strawberries and put them in a bowl ready to use
• ...and left them there

Good question. The difference is nuance.

담았어요

Simply means:

• put it in
• placed it in a bowl

담아 두었어요

Means:

• put it in and left it that way
• put it in beforehand / in preparation
• set it aside ready for later

So 아/어 두다 adds the idea of a resulting state that continues, or a preparatory action.

In Korean, when verbs are connected, the final verb usually carries the tense and politeness for the whole sentence.

So in:

• 씻어서
• 담아 두었어요

the final verb 두었어요 shows:

• past tense
• polite style

The earlier connected verb 씻어서 does not need its own past tense marking.

This is very normal in Korean.

They are:

• 씻다 = to wash
• 담다 = to put in, place into, contain
• 두다 = to put, leave; in 아/어 두다, it helps express do something and leave it that way

So the sentence is built from:

• 씻다 → 씻어서
• 담다
  • 두다 → 담아 두었어요

Because 담아 두다 is usually written as a main verb plus the auxiliary verb 두다.

So it is commonly spaced like this:

• 담아 두었어요

In everyday writing, especially casual writing, you may also see the contracted form:

• 담아뒀어요

Both represent the same basic meaning. The spaced form is clearer for learners and is very standard.

The subject is omitted, which is very common in Korean.

Depending on context, it could mean:

• I washed them
• we washed them
• she/he washed them

Korean often leaves out subjects when they are already understood from the situation.

So the sentence focuses more on the action and result than on explicitly naming the doer.

Not necessarily.

The past tense tells you that the action of washing and placing them in the bowl was completed in the past. But because this uses 아/어 두다, it often implies that the result of that action still matters now.

So the feeling is often:

• the strawberries were washed and placed in the bowl earlier,
• and they are likely still there, ready.

In other words, the past tense refers to when the preparation happened, not necessarily to whether the result has disappeared.

Grammatically, 딸기 by itself does not have to show plural.

Korean often leaves number unmarked unless it is important. So 딸기 can refer to:

• one strawberry
• strawberries in general
• several strawberries

In this sentence, the natural meaning is strawberries, even without a plural marker.

If someone really wanted to emphasize plurality, they might say 딸기들, but that is usually unnecessary here.
