A natural breakdown is:

• 친구가 = friend + subject marker
• 추천한 = recommended / that recommended in a noun-modifying form
• 만화를 = comic + object marker
• 읽어 봤어요 = tried reading / have read

So the structure is basically:

[friend-subject] [recommended-comic-object] [tried reading]

More naturally in English order: I tried reading the comic that my friend recommended.

가 is the subject marker. It marks 친구 as the one doing the recommending.

So in this sentence:

• 친구가 추천한 만화 = the comic that my friend recommended

Here, 친구 is the subject of 추천한, not of 읽어 봤어요.

If you used 친구는 instead, the sentence would sound more like you were making friend the topic, possibly with a contrastive nuance.

In Korean, verbs can directly modify nouns by using a noun-modifying form.

So:

• 추천하다 = to recommend
• 추천한 = recommended / that someone recommended

That means:

• 추천한 만화 = the comic that was recommended / the comic someone recommended

And with 친구가 added:

• 친구가 추천한 만화 = the comic that my friend recommended

This is how Korean makes relative clauses, where English would usually use that, which, or who.

Because 추천한 is modifying a noun, while 추천했어요 is a complete sentence ending.

Compare:

• 친구가 추천했어요. = My friend recommended it.
• 친구가 추천한 만화 = the comic that my friend recommended

When a verb comes before a noun and describes it, Korean uses a noun-modifying form, not a normal sentence-final form.

For a completed action modifying a noun, Korean often uses -ㄴ/은:

• 하다 → 한
• so 추천하다 → 추천한

를 is the object marker. It marks 만화 as the thing being read.

So:

• 만화를 읽어 봤어요 = tried reading the comic

The comic is the direct object of 읽어 보다.

Here, 보다 is not the main verb to see in a literal sense. It is being used as an auxiliary verb in the pattern -아/어 보다, which means:

• to try doing something
• sometimes to do something and see what it’s like
• sometimes to have the experience of doing something

So:

• 읽어 보다 = to try reading
• 읽어 봤어요 = tried reading / have read it

Depending on context, this can sound like:

• I tried reading the comic my friend recommended.
• I’ve read the comic my friend recommended.

The nuance of trying/experiencing is often present.

Because the action happened before the time of speaking.

In Korean, the past tense often covers both:

• a simple past idea: I tried reading it
• a present perfect idea: I’ve tried reading it

So 읽어 봤어요 does not always have to be translated with a simple past in English. The exact English tense depends on context.

Yes, both forms are commonly seen.

Here 보다 is functioning as an auxiliary after 읽어. With auxiliary verbs in Korean, spacing can be flexible in actual usage:

• 읽어 봤어요
• 읽어봤어요

Both mean the same thing here.

Learners will often see the spaced form in explanations because it makes the grammar easier to notice: 읽어 + 보다.

Yes. The subject I is omitted because Korean often leaves out subjects when they are obvious from context.

So the full idea is something like:

• (제가 / 나는) 친구가 추천한 만화를 읽어 봤어요.

But in natural Korean, saying I is often unnecessary.

So the sentence usually implies:

• I tried reading the comic my friend recommended.

It is in the polite informal style, often called 해요체.

That makes it appropriate for many everyday situations.

Related forms:

• 읽어 봤어 = casual, used with close friends
• 읽어 봤어요 = polite everyday style
• 읽어 봤습니다 / 읽어 보았습니다 = more formal

So this sentence sounds polite and natural for normal conversation.

A common pronunciation is roughly:

• 읽어 → 일거
• 봤어요 → 봐써요

So the whole phrase sounds close to:

• 일거 봐써요

This happens because Korean pronunciation often changes when final consonants meet the next sound. So the written form and spoken form are not always identical.
