Korean very often omits subjects when they are clear from context, so in natural conversation this sentence could easily appear without 그녀는.

Here, 그녀는 is used to make the subject explicit:

• 그녀 = she
• 는 = topic marker

So 그녀는 means as for her / she.

A learner should also know that 그녀 is less common in everyday spoken Korean than she is in English. In real conversation, Koreans often:

• omit the pronoun entirely, or
• use the person’s name, title, or kinship term instead.

So this sentence is grammatically fine, but a more natural spoken version in context might simply begin with 뛰어가다가...

뛰어가다가 can be broken down like this:

• 뛰다 = to run / jump
• 가다 = to go
• -아/어 가다 = to go on while doing something, or to move away doing that action
• -다가 = while doing, and then...

So 뛰어가다가 means something like:

• while running along
• while running somewhere
• while running and then...

It gives the sense that she was in the middle of running toward or away somewhere when the next event happened.

-다가 and -고 are different.

• -고 simply links actions: did A and did B
• -다가 means while doing A, then B happened, often with an interruption or change

So:

• 뛰어가고 넘어졌어 = She ran and fell.
• 뛰어가다가 넘어졌어 = She was running, and then she fell.

In this sentence, -다가 is a better fit because falling happened during the running, not just after it as a separate event.

Good question. Both involve running, but they are not exactly the same.

• 뛰다 = to run / jump
• 뛰어가다 = to run somewhere, to go by running

The 가다 adds a direction or movement-away sense. It suggests the person is not just running in general, but running along to somewhere.

So:

• 그녀는 뛰다가... = She was running...
• 그녀는 뛰어가다가... = She was running along / running off / running to somewhere...

In many contexts, both could work, but 뛰어가다 feels more vivid and directional.

Here 에서 marks the place where the event happened.

• 계단 = stairs / staircase
• 에서 = at, in, on, from the place where an action occurs

So 계단에서 넘어졌어 means:

• fell on the stairs
• fell at the staircase

A useful way to think about it:

• 에 is often used for destination, existence, or resulting location
• 에서 is often used for the location where an action happens

Since 넘어지다 is an event happening at that place, 계단에서 is natural.

Breakdown:

• 넘어지다 = to fall
• 넘어졌- = fell
• -지만 = but / although

So 넘어졌지만 means:

• she fell, but...
• although she fell...

-지만 connects two clauses that contrast with each other. In this sentence:

• falling down sounds serious,
• but the next part says she was not badly hurt.

That contrast is exactly what -지만 is used for.

Not literally. 크게 comes from 크다 (to be big), but as an adverb it often means:

• greatly
• seriously
• badly
• to a large extent

So 크게 아프다 means:

• to be hurt badly
• to be seriously injured
• to hurt a lot

In English we do not usually say bigly hurt, but Korean often uses size words metaphorically this way.

So 크게 아프지는 않았어 means she wasn’t badly hurt or wasn’t seriously injured.

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

Breakdown:

• 아프다 = to hurt / to be painful / to be injured
• 아프지는 않다 = to not be hurt, with contrast or emphasis
• 않았어 = was not (past, casual)

The key is -지는 않다.

This pattern often adds a nuance like:

• not exactly...
• not really...
• not, at least
• not in that respect

So 크게 아프지는 않았어 does not just mean a plain wasn’t hurt badly. It often carries a slight contrastive feeling:

• she did fall,
• maybe it hurt somewhat,
• but she wasn’t badly hurt

That 는 adds subtle emphasis or contrast. Compare:

• 크게 아프지 않았어 = she wasn’t badly hurt
• 크게 아프지는 않았어 = she wasn’t badly hurt, at least / not seriously, anyway

Not necessarily.

It usually means she was not hurt badly or not seriously hurt. It leaves open the possibility that:

• she felt some pain,
• she got a little hurt,
• or it was not as bad as expected.

Because of 크게 and the contrastive -지는, the sentence suggests:

• she fell,
• but the result was not severe.

So the meaning is closer to:

• She wasn’t badly hurt than
• She wasn’t hurt at all

않았어 is a casual, informal ending.

Breakdown:

• 않았다 = did not / was not (plain past)
• 않았어 = casual spoken form

This style is used:

• with friends,
• with younger people,
• in casual narration,
• in diary-like or conversational contexts

More polite versions would be:

• 그녀는 뛰어가다가 계단에서 넘어졌지만 크게 아프지는 않았어요.
• 그녀는 뛰어가다가 계단에서 넘어졌지만 크게 아프지는 않았습니다.

So the original sentence is in informal casual speech.

Yes. The sentence is built to tell a small story very naturally:

1. 뛰어가다가 — she was in the middle of running
2. 계단에서 넘어졌지만 — she fell on the stairs, but...
3. 크게 아프지는 않았어 — the result was not serious

So the sentence has a very typical Korean narrative structure:

• background action
• main event
• contrastive result

This makes it sound smooth and natural, especially for describing accidents or unexpected events.
