있어서 is 있다 + -어서.

Here, -아서/어서 connects two clauses and often gives a reason or background. So 물이 있어서 means something like:

• because there was water
• since there was water
• there being water

In this sentence, it explains why the speaker touched the faucet.

에 marks a location when something exists or is located somewhere.

So:

• 세면대 = sink / washbasin
• 아래 = below / under
• 세면대 아래에 = under the sink

Because the sentence says water was there, 에 is the natural particle:

• 세면대 아래에 물이 있어 = There is water under the sink.

Because 물 is the thing that exists, so it takes the subject marker 이/가, not the object marker 을/를.

With 있다, the thing that exists is usually marked with 이/가:

• 물이 있다 = water exists / there is water
• 책이 있다 = there is a book

Using 물을 있다 would be incorrect here.

수도꼭지 means faucet or tap.

So:

• 수도 relates to running water / water supply
• 꼭지 can mean a nozzle, spout, or knob-like end

As a whole, 수도꼭지 is the faucet/tap attached to a sink.

Because it is the direct object of 만지다 (to touch).

• 수도꼭지를 만졌어 = I touched the faucet.

The object marker 을/를 shows what was touched.

잠깐 means for a moment, briefly, or for a second.

It modifies the verb 만졌는데, so:

• 수도꼭지를 잠깐 만졌는데 = I touched the faucet briefly / for a moment

In Korean, adverbs like 잠깐 often come right before the verb they modify.

-는데 can do several things, and here it mainly gives background and leads into what happened next.

So 만졌는데 can be understood like:

• I touched it, and...
• when I touched it,...
• I touched it, but...

In this sentence, it introduces the result or reaction: after touching the faucet, the speaker found it very cold.

So the feeling is not strong contradiction, but more of a natural lead-in to the next clause.

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

From context, the faucet is what was very cold. So the full idea is:

• 수도꼭지가 너무 차가웠어 = The faucet was very cold.

Korean often leaves out subjects when they are obvious from context.

차가웠어 is the past form of 차갑다 (to be cold).

It is in the past because the speaker is describing what they felt at that moment in the story:

• there was water
• they touched the faucet
• it was very cold

So 차가웠어 means was cold, not is cold.

차가웠어 is in the casual, informal speech style.

The dictionary form is 차갑다. Depending on politeness level, it could become:

• 차가웠어 = casual
• 차가웠어요 = polite
• 차가웠습니다 = formal

So this sentence sounds like everyday spoken Korean between friends, in narration, or in a relaxed context.

Korean often puts background information first and the main result later.

This sentence is organized like this:

1. 세면대 아래에 물이 있어서
   background / reason
2. 수도꼭지를 잠깐 만졌는데
   action
3. 너무 차가웠어
   result / reaction

English might prefer something like I briefly touched the faucet because there was water under the sink, and it was very cold, but Korean naturally builds up to the main point at the end.

Yes. A common alternative is 세면대 밑.

• 아래 = below / lower part
• 밑 = under / underneath

In many everyday contexts, both work similarly:

• 세면대 아래에 물이 있어
• 세면대 밑에 물이 있어

Both can mean There is water under the sink.
아래 can sound a little more neutral or spatial, while 밑 often feels very natural in everyday speech too.

Because Korean often omits pronouns when the meaning is clear.

In English, you usually need it:

• It was very cold.

In Korean, if everyone already knows what is being talked about, you can simply say:

• 너무 차가웠어 = was very cold / it was very cold

The listener understands from context that the faucet was cold. This kind of omission is extremely common in Korean.
