Because 밀다 means to push, and the thing being pushed takes the object marker -을/를.

• 문 손잡이 = door handle
• 문 손잡이를 = the door handle as the object of 밀다

So 문 손잡이를 밀어도 means even if I push the door handle or more naturally even when I pushed the door handle.

문 손잡이 literally means door handle:

• 문 = door
• 손잡이 = handle

Korean often puts nouns together like this, where the first noun describes the second. So 문 손잡이 is not a full possessive phrase like the handle of the door; it is just a natural noun combination meaning door handle.

In this sentence, the speaker is specifically talking about pushing and pulling the handle, not just the door in general.

-아/어도 usually means even if, even though, or although.

So:

• 밀다 = to push
• 밀어도 = even if I push / even though I pushed

In this sentence, it gives the idea:

• Even though I pushed it, it didn’t open...
• or more naturally, I pushed it, but it didn’t open...

So 밀어도 안 열려서 has the feeling of pushing didn’t work.

This is a very common question because Korean distinguishes between:

• 열다 = to open something
• 열리다 = to open / to be opened

With a door, Korean very often says:

• 문이 열리다 = the door opens / the door is opened
• 문이 안 열리다 = the door doesn’t open

So 안 열려서 comes from 안 열리어서, which contracts to 안 열려서.

That means the sentence is not saying I didn’t open it, but rather it wouldn’t open or it didn’t open.

-아서/어서 often connects two actions or situations. It can mean:

• because
• so
• sometimes just a natural sequence of events

Here, 안 열려서 당겨 봤어 means:

• It wouldn’t open, so I tried pulling it
• or Because it didn’t open, I tried pulling it

So -서 links the failed result with the next action.

No. Here 보다 does not mean to see in the usual sense.

When 보다 comes after another verb, -아/어 보다 means to try doing something.

So:

• 당기다 = to pull
• 당겨 보다 = to try pulling
• 당겨 봤어 = I tried pulling it

This is one of the most useful Korean grammar patterns. It shows an attempt or experiment.

So the sentence is not just I pulled it. It is more specifically I tried pulling it.

It could, but Korean very often leaves out words that are already obvious from context.

After 문 손잡이를 밀어도, the listener already knows what is being talked about. So in the next clause, Korean naturally omits the repeated object.

Full version:

• 문 손잡이를 밀어도 안 열려서 문 손잡이를 당겨 봤어

Natural spoken version:

• 문 손잡이를 밀어도 안 열려서 당겨 봤어

The omitted object is understood as the handle or possibly the door, depending on context.

Yes. 봤어 is informal, casual speech.

Here are some levels:

• 당겨 봤어 = casual / plain informal
• 당겨 봤어요 = polite
• 당겨 보았습니다 or 당겨 봤습니다 = formal

So this sentence sounds like something you would say to a friend, family member, or someone you speak casually with.

These are normal conjugated spoken forms.

• 밀다 → 밀어
• 열리다 → 열리어 → 열려
• 당기다 → 당기어 → 당겨

In modern Korean, combinations like -이어, -기어, -리어 often contract in speech and writing:

• 당기어 → 당겨
• 열리어 → 열려

So these are not strange special forms; they are just the standard natural contractions.

The subject is omitted because it is obvious from context. It is something like:

• 문이 = the door
• or more loosely it

So 안 열려서 really means:

• the door didn’t open
• it wouldn’t open

Korean often drops subjects when they are clear, especially in everyday speech.

Yes, exactly. The sentence has a very natural trial-and-error feeling:

1. I pushed the handle
2. It didn’t open
3. So I tried pulling it

That is why -어도, 안 열려서, and -아/어 보다 work so well together here. The sentence sounds like someone checking which way the door opens.
