It means on top of the kitchen shelf.

• 주방 = kitchen
• 선반 = shelf
• 위 = top, above, on top
• 에 = location particle, often marking where something is

So 주방 선반 위에 literally means on the top of the kitchen shelf or more naturally on the kitchen shelf.

Here, 에 marks the location where the cups are.

In this sentence, the cups exist on the shelf, so 에 is the natural particle to use.

Compare:

• 선반 위에 컵이 있어요 = There are cups on the shelf.
• 학교에 가요 = I go to school.

So 에 can mark:

• a location of existence
• a destination
• a point in time

In this sentence, it is marking the place where the cups are.

Because 컵 is the thing being described as many, not the thing being directly acted on in that part of the sentence.

• 컵이 많다 = there are many cups / cups are many

The adjective 많다 usually takes the subject marker 이/가, not the object marker 을/를.

So:

• 컵이 많아요 = There are many cups.
• not 컵을 많아요

Later in the sentence, the speaker says 정리했어요 (organized/tidied up), and the object of that verb is omitted because it is obvious: the speaker organized the cups.

너무 means too, too much, or sometimes just very, depending on context.

Here, because the sentence expresses a reason for tidying up, 너무 많아서 most naturally means:

• because there were too many

So:

• 컵이 너무 많아서 = because there were too many cups

In everyday Korean, 너무 is also often used casually to mean really/very:

• 너무 맛있어요 = It’s really delicious.

But in this sentence, too many fits best.

많아서 is the -아서/-어서 connective form of 많다 (to be many / to be a lot).

It connects the first idea to the second and often means:

• because
• so
• and so

So:

• 많다 = to be many
• 많아서 = because there are many / so there are many

In this sentence:

• 컵이 너무 많아서 정리했어요
• Because there were too many cups, I organized them.

This form often gives a reason for the action in the second clause.

Because the speaker is saying they already did the tidying.

• 정리하다 = to organize, put in order, tidy up
• 정리해요 = organize / I organize / I’m organizing
• 정리했어요 = organized / tidied up

So the full sentence describes:

1. there were too many cups on the shelf
2. as a result, the speaker tidied them up

Korean often omits words that are obvious from context.

Even though the sentence does not say 컵을 정리했어요, that is understood naturally. The full meaning is basically:

• 주방 선반 위에 컵이 너무 많아서 (컵을) 정리했어요.

In English, we usually need something like I organized them. In Korean, once the cups have already been mentioned, the object can be left out.

This kind of omission is very common in Korean.

It can mean several related things depending on context:

• organize
• tidy up
• put in order
• sometimes sort out

In this sentence, 정리했어요 probably means something like:

• I tidied them up
• I organized them
• I put them away neatly

It does not necessarily mean deep cleaning like washing or scrubbing. It is more about making things orderly.

The sentence follows a very common Korean pattern:

[place] + [thing] + [description/reason] + [main action]

Breaking it down:

• 주방 선반 위에 = on the kitchen shelf
• 컵이 = cups
• 너무 많아서 = because there were too many
• 정리했어요 = I tidied up / organized them

So the logic is:

On the kitchen shelf, there were too many cups, so I organized them.

Korean often puts the reason first and the main action at the end.

Because Korean often leaves out the subject when it is understood from context.

In English, we normally say:

• I organized them.

In Korean, 정리했어요 does not explicitly say I, but in normal conversation it is often understood that the speaker means I.

So the sentence naturally implies:

• I tidied them up because there were too many cups on the kitchen shelf.

Yes, that is a very natural translation.

Depending on context, possible translations include:

• There were too many cups on the kitchen shelf, so I organized them.
• There were too many cups on the kitchen shelf, so I tidied them up.
• There were too many cups on the kitchen shelf, so I put them away.

The exact English wording depends on what kind of 정리 the speaker means in the situation.

In Korean, 많다 is the normal and natural way to say there are many.

So:

• 컵이 많아요 = There are many cups.

You could sometimes express a similar idea in other ways, but N이 많다 is the standard pattern.

That is why 컵이 너무 많아서 sounds natural and common.

정리했어요 is in the polite informal style, often called the -요 style.

It is polite and very common in everyday conversation.

Compare:

• 정리했어요 = polite
• 정리했어 = casual, used with friends or younger people
• 정리했습니다 = more formal

So this sentence sounds polite and natural for everyday speech.
