국자 means ladle.

The -를 is the object particle. It marks 국자 as the thing being washed.

• 국자 = ladle
• 국자를 = the ladle (as the object of the verb)

So in this sentence, 국자를 씻어서 means washed the ladle and...

씻어서 comes from the verb 씻다 meaning to wash.

The ending -어서 connects this verb to the next action. In this sentence, it means something like:

• after washing
• wash and then
• sometimes simply and

So 국자를 씻어서 냄비 옆에 두었어요 means I washed the ladle and then put it next to the pot.

Here, -어서 is mainly showing that the first action happens before the second.

Both -아서/어서 and -고 can connect actions, and in many situations both are possible.

• 씻고 냄비 옆에 두었어요
• 씻어서 냄비 옆에 두었어요

Both can mean washed it and put it next to the pot.

A useful beginner-level distinction is:

• -고 = simple listing or sequencing: and
• -아서/어서 = often feels a little more connected, like after doing X or so

In this sentence, 씻어서 sounds natural because washing the ladle is closely connected to putting it down.

• 냄비 = pot
• 옆 = side
• 옆에 = at the side of / next to

So 냄비 옆에 means next to the pot or beside the pot.

The 에 here marks the location where the ladle was placed.

에 is commonly used for a location or destination, especially with verbs of placement or existence.

In this sentence, the ladle is being placed somewhere:

• 냄비 옆에 두었어요 = (I) put it next to the pot

So 에 marks the place where the ladle ended up.

두었어요 comes from 두다, which often means:

• to put
• to place
• to leave

So 냄비 옆에 두었어요 means put it next to the pot or left it next to the pot.

In context, left it next to the pot can sound very natural in English.

두었어요 is:

• past tense
• polite speech

So it means put / placed / left in a polite, conversational style.

The ending -어요 is a standard polite ending.
The -었- shows past tense.

So:

• 두다 = to put
• 두었어요 = put / placed / left

In Korean, when two verbs are linked in one sentence, the tense is often shown only on the final verb.

So:

• 씻어서 ... 두었어요

already tells you the whole sequence is in the past.

You do not normally need to say something like 씻었어서 here. That would sound unnatural for this sentence.

This is very common in Korean: earlier linked verbs often appear in a neutral connective form, and the final verb carries the tense.

The subject is omitted because Korean often leaves out information that is clear from context.

So 국자를 씻어서 냄비 옆에 두었어요 could mean:

• I washed the ladle and put it next to the pot
• He/She washed the ladle and put it next to the pot
• They washed the ladle and put it next to the pot

In many real conversations, the listener already knows who is being talked about, so Korean does not need to state the subject.

Yes, in a sentence like this, the normal interpretation is that the same subject did both actions.

So the natural reading is:

• Someone washed the ladle
• that same person put it next to the pot

That is one reason this sentence feels very smooth and natural.

Yes. Depending on context, 두다 can be translated as:

• put
• place
• leave

So this sentence could be understood as:

• I washed the ladle and put it next to the pot.
• I washed the ladle and left it next to the pot.

Both are reasonable.

Yes, but they are often similar in everyday use.

• 두다 often has a broad sense of putting or leaving something somewhere.
• 놓다 often emphasizes the act of setting something down or placing it.

In many situations, both can work:

• 냄비 옆에 두었어요
• 냄비 옆에 놓았어요

The sentence with 두었어요 can feel a little like put it there and left it there.

A few pronunciation changes happen:

• 국자를 is often pronounced close to 국짜를
• 씻어서 is often pronounced close to 씨서서
• 옆에 is pronounced close to 여페
• 두었어요 is often pronounced close to 두어써요

So the whole sentence sounds roughly like:

국짜를 씨서서 냄비 여페 두어써요

That is a rough pronunciation guide, not a perfect romanization.

Not really in a strong purpose sense. Here, -어서 most naturally shows sequence or close connection:

• washed it, then put it next to the pot

It is not mainly expressing intention or purpose.
If you wanted to emphasize purpose, Korean would usually use a different structure.

The sentence breaks down like this:

• 국자를 = the ladle (object)
• 씻어서 = washing it / after washing it
• 냄비 옆에 = next to the pot
• 두었어요 = put / left

So the structure is:

object + first action + location + final action

Very literally, it is something like:

(I) washed the ladle and put it next to the pot.
