-다가 means while doing something / in the middle of doing something, then something else happened.

So 신문을 읽다가 재미있는 기사를 봤어 means:

• I was reading the newspaper,
• and then, during that, I saw a interesting article.

Using 읽고 would just mean read and then in a more simple sequence:

• 신문을 읽고 재미있는 기사를 봤어 = I read the newspaper and then saw an interesting article.

That sounds a bit odd here, because seeing the article is really part of the reading process. -다가 captures that interruption or discovery much better.

Not exactly.

• 읽다가 = while reading / in the middle of reading, then something happened
• 읽으면서 = while reading, at the same time

In this sentence, 읽다가 is more natural because the speaker is describing a new event that occurred during the action of reading: they came across an interesting article.

Compare:

• 신문을 읽다가 재미있는 기사를 봤어
  = I was reading the newspaper and happened to see an interesting article.

• 신문을 읽으면서 재미있는 기사를 봤어
  = While reading the newspaper, I saw an interesting article.

The second is not impossible, but -다가 gives the stronger sense of something happened in the middle of the first action.

에 marks a time expression in many cases.

So:

• 오늘 아침에 = this morning

In Korean, time words sometimes appear with 에, and sometimes without it. With 오늘, 내일, 어제, Korean often omits 에:

• 오늘 아침 신문을 읽다가...
• 오늘 아침에 신문을 읽다가...

Both are natural. Adding 에 can make the time phrase feel a little more clearly marked, but there is no big meaning difference here.

Yes, this is a very normal Korean expression.

• 신문 = newspaper
• 읽다 = to read

So 신문을 읽다 is exactly the standard way to say read the newspaper.

Korean also uses 보다 with many media-related things, such as:

• 영화를 보다 = watch a movie
• 텔레비전을 보다 = watch TV
• 신문을 보다 can also exist, but it often feels more like look through / check / read depending on context.

In this sentence, 신문을 읽다가 is the clearest and most straightforward choice.

Because each noun is the object of its own verb.

• 신문을 읽다가
  신문 is the object of 읽다

• 재미있는 기사를 봤어
  기사 is the object of 보다

So the sentence contains two actions:

1. reading the newspaper
2. seeing an interesting article

Each action has its own object, so each noun gets an object marker.

재미있는 is the adjective-like form modifying the noun 기사.

Breakdown:

• 재미있다 = to be interesting / fun
• 재미있는 = interesting, fun (when placed before a noun)
• 기사 = article

So:

• 재미있는 기사 = an interesting article

This is how Korean descriptive verbs work before nouns:

• 큰 집 = a big house
• 예쁜 꽃 = a pretty flower
• 재미있는 기사 = an interesting article

봤어 is the contracted spoken form of 보았어.

• 보다 → past stem 보았-
• in normal speech, 보았어 becomes 봤어

This contraction is extremely common and natural.

Similar contractions:

• 가았어 does not happen, but
• 하였다 → 했다
• 되었어 → 됐어
• 주었어 → 줬어

So 봤어 is just the normal conversational form.

The ending 봤어 is in informal casual speech.

This style is used:

• with friends
• with younger people
• with close family
• in casual conversation

The more polite version would be:

• 오늘 아침에 신문을 읽다가 재미있는 기사를 봤어요.

The plain dictionary form would be:

• 오늘 아침에 신문을 읽다가 재미있는 기사를 보았다.
• ...봤다 in a more conversational written style

So the sentence as written sounds friendly and casual.

Because Korean often omits the subject when it is obvious from context.

In English, you usually need I:

• I saw an interesting article this morning...

In Korean, if it is clear the speaker is talking about their own experience, the subject is usually dropped:

• 오늘 아침에 신문을 읽다가 재미있는 기사를 봤어.

A full version would be possible:

• 나는 오늘 아침에 신문을 읽다가 재미있는 기사를 봤어.

But that often sounds unnecessary unless you are emphasizing I.

It can carry a broader meaning than just the literal English verb see.

In this context, 재미있는 기사를 봤어 can mean:

• saw an interesting article
• came across an interesting article
• noticed an interesting article
• found an interesting article while reading

Because the person was already reading the newspaper, 봤어 here naturally suggests encountering the article during that activity, not just visually seeing it for one second.

It is mostly neutral, but -다가 adds a small sense of something happened during another action.

So the feeling is:

• I was reading the newspaper this morning,
• and in the middle of that, I came across an interesting article.

It sounds slightly more vivid than a plain sequence of events. It feels like the speaker is telling you how they discovered the article.

By itself, it most directly means the speaker saw/came across the article.

It does not automatically guarantee that they read the whole article. Korean 보다 here can cover a range from:

• noticing it
• looking at it
• reading it

If you wanted to make it clearer that the person fully read it, you could say something like:

• 재미있는 기사를 읽었어 = I read an interesting article
• 재미있는 기사를 발견했어 = I discovered/found an interesting article

So the original sentence emphasizes the moment of encountering the article while reading the newspaper.

Yes. 기사 is one of those Korean words with multiple meanings depending on context.

Common meanings include:

• news article
• report/article
• driver (for example, a chauffeur or taxi driver in some contexts)
• engineer/technician in certain compounds
• knight in historical/fantasy contexts

But with 신문 right before it, 기사 clearly means article.

So 신문을 읽다가 재미있는 기사를 봤어 can only naturally be understood as I saw an interesting article while reading the newspaper this morning.

Here are some natural variations:

• Polite casual:
  오늘 아침에 신문을 읽다가 재미있는 기사를 봤어요.

• Formal written/plain:
  오늘 아침에 신문을 읽다가 재미있는 기사를 봤다.

• More formal polite:
  오늘 아침에 신문을 읽다가 재미있는 기사를 봤습니다.

The grammar stays the same; only the ending changes.

Yes, but the nuance changes.

• 읽다가 = while reading, in the middle of reading, then I saw...
• 읽었는데 = I read the newspaper, and/when..., with a looser connection

So:

• 신문을 읽다가 재미있는 기사를 봤어
  is tighter and more immediate.

• 신문을 읽었는데 재미있는 기사를 봤어
  is less natural for this exact situation, because seeing the article is really part of reading the newspaper.

If your goal is to express I came across something while reading, -다가 is the best choice.
