ani, jeoneun dachiji anhasseoyo.

아니 here means No or Well, no. It is often used to reject, correct, or soften a previous statement or assumption.

In conversation, it can sound like:

• No, ...
• Actually, no, ...
• Well, no, ...

It is slightly less formal than 아니요, which is the more standard polite form for no by itself.

저 means I in a polite/humble way.
The particle 는 makes it the topic of the sentence.

So:

• 저 = I
• 저는 = as for me / I

In this sentence, 저는 helps emphasize that the speaker is talking about their own situation: As for me, I wasn’t hurt.

In everyday Korean, speakers often include 저는 when contrasting themselves with something else or when clearly setting the topic.

Both mean I with a topic particle, but the pronoun changes the politeness level:

• 저는 = polite/humble I
• 나는 = plain/casual I

So:

• 저는 다치지 않았어요 is polite.
• 나는 다치지 않았어 is casual.

If you are speaking politely, 저는 is the natural choice.

It is made from the verb 다치다, which means to get hurt / to be injured.

Breakdown:

• 다치다 = to get hurt
• 다치지 않다 = to not get hurt
• 다치지 않았어요 = did not get hurt

More specifically:

• -지 않다 is a standard negation pattern meaning not do
• 않았어요 is the polite past form of 않다

So the structure is:

다치-지 않-았-어요
verb stem + negation + past tense + polite ending

Korean often uses the past tense here because it is talking about the event of getting hurt.

So 다치지 않았어요 literally means:

• I did not get hurt
• I wasn’t injured

This focuses on whether an injury happened.

In English, depending on context, you might translate it as:

• I wasn’t hurt
• I didn’t get hurt
• sometimes even I’m not hurt

But the Korean grammar is past because it refers to the result of a past event or incident.

Yes. 안 다쳤어요 is very common and means the same thing.

Compare:

• 다치지 않았어요 = did not get hurt
• 안 다쳤어요 = didn’t get hurt

Both are natural.
The 안 form is shorter and often more conversational.

A learner should know both:

• 안 + verb = common short negation
• -지 않다 = standard negation pattern, sometimes a bit more formal or neutral

다치다 usually means to get hurt, to be injured, or to suffer an injury.

This is important because English hurt can be transitive or intransitive:

• I hurt him = I caused pain
• I got hurt = I was injured

Korean 다치다 matches the second idea:

• I got hurt
• I was injured

If you want to say that someone caused pain to someone else, Korean usually uses a different structure, not 다치다 in the same way as English hurt.

They are related, but not exactly the same in tone.

• 아니요 = polite No
• 아니 = less formal, often used before continuing a sentence

In this sentence, 아니, 저는 다치지 않았어요 sounds natural in speech, like:

• No, I wasn’t hurt.
• Actually, no, I wasn’t hurt.

If you wanted a slightly more formally polite version, you could say:

• 아니요, 저는 다치지 않았어요.

Yes. You can say:

• 아니, 다치지 않았어요.

Korean often drops subjects and topics when they are obvious from context.

Adding 저는 makes it clearer or more contrastive:

• As for me, I wasn’t hurt.

Without 저는, the sentence is still natural if everyone already knows who is being talked about.

는 marks the topic and often adds a slight sense of contrast.

So 저는 다치지 않았어요 can feel like:

• I, at least, wasn’t hurt
• As for me, I wasn’t hurt

This does not always need to be translated directly, but it can matter in conversation. For example, it may suggest:

• maybe someone else was hurt
• maybe the speaker is correcting a misunderstanding
• maybe the speaker is shifting the topic to themselves

That is one reason 저는 fits well after 아니.

Here are common style levels:

More formal

• 아니요, 저는 다치지 않았습니다.

Polite everyday

• 아니, 저는 다치지 않았어요.
• 아니요, 저는 다치지 않았어요.

Casual

• 아니, 나는 다치지 않았어.
• 아니, 나 안 다쳤어.

The original sentence is polite everyday Korean.

Although it is written 않았어요, it is pronounced more like 아나써요 in normal speech.

So:

• 다치지 않았어요 sounds roughly like 다치지 아나써요

This happens because the consonants in 않 change in pronunciation when followed by a vowel.

Learners often find the spelling harder than the actual spoken form. It is good to recognize both:

• written: 않았어요
• spoken: closer to 아나써요
