산 is the noun-modifying form of 사다, which means to buy.

So:

• 사다 = to buy
• 산 컴퓨터 = the computer (someone) bought

In English, we often use a relative clause like the computer that I bought, but in Korean that idea comes before the noun:

• 새로 산 컴퓨터 = the newly bought computer / the computer I bought recently

So 산 does not mean mountain here. It is the verb 사다 turned into a form that describes 컴퓨터.

새 and 새로 are related, but they are used differently.

• 새 = new (describes a noun directly)
  • 새 컴퓨터 = a new computer
• 새로 = newly / freshly / recently (an adverb, so it modifies a verb)
  • 새로 산 컴퓨터 = a computer that was newly/recently bought

So in this sentence:

• 새 컴퓨터 설명서 would suggest the manual for a new computer
• 새로 산 컴퓨터 설명서 emphasizes the computer was recently bought

That is a slightly different nuance.

A natural breakdown is:

• 새로 산 = newly bought / recently bought
• 컴퓨터 설명서 = computer manual
• 를 = object marker
• 읽어 봤어요 = tried reading / read through

So the structure is:

[새로 산 컴퓨터] 설명서를 읽어 봤어요.

That means:

• 새로 산 컴퓨터 = the computer I recently bought
• 설명서 = manual
• together: the manual for the computer I recently bought

Korean often places modifying information before the noun, and it also commonly stacks nouns together, so 컴퓨터 설명서 literally looks like computer manual, meaning manual for the computer.

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

So this sentence could mean:

• I tried reading the manual...
• We tried reading the manual...
• even He/She tried reading the manual...

depending on the situation.

In real Korean conversation, pronouns like I and you are omitted much more often than in English. If the speaker is talking about their own recently bought computer, listeners will naturally understand that.

설명서 means manual, instructions, or instruction booklet.

The -를 is the object marker. It shows that 설명서 is the thing being read.

So:

• 설명서 = manual
• 설명서를 = the manual (as the object of the verb)

You use 를 because 설명서 ends in a vowel sound. If a noun ended in a consonant, you would normally use 을 instead.

This is a very common learner question.

• 읽었어요 = read
• 읽어 봤어요 = tried reading / read it to see / had a look through it

The grammar -아/어 보다 adds the idea of trying something or doing it for experience.

So:

• 설명서를 읽었어요 = I read the manual.
• 설명서를 읽어 봤어요 = I tried reading the manual. / I took a look through the manual.

In many contexts, 읽어 봤어요 sounds a little softer and more exploratory, like the speaker checked it out to see what it said.

Not always in a strict, literal sense.

Depending on context, -아/어 보다 can mean:

1. to try doing something
2. to do something and see
3. to have the experience of doing something

So here, 읽어 봤어요 could be understood as:

• I tried reading the manual
• I looked through the manual
• I read the manual to see what it said

It often has a nuance of giving it a try rather than simply stating the bare fact that the reading happened.

봤어요 is the contracted, natural spoken form of 보았어요.

For the grammar -아/어 보다:

• 읽어 보았어요 is grammatically correct
• 읽어 봤어요 is the normal shortened form in everyday speech

This kind of contraction is very common in Korean:

• 보았어요 → 봤어요
• 가았어요 does not happen like this, but many common verb combinations contract in natural speech

So 읽어 봤어요 is just the usual conversational form.

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

That means it is polite and very common in everyday conversation.

Compare:

• 읽어 봤어요 = polite everyday speech
• 읽어 봤어 = casual speech
• 읽어 보았습니다 or 읽어 봤습니다 = more formal speech

So this sentence sounds natural in normal polite conversation.

The sentence does not explicitly say.

In Korean, when a verb modifies a noun like this, the subject inside that phrase is often omitted if it is understood from context.

So 새로 산 컴퓨터 literally means:

• the computer that [someone] recently bought

Usually, in context, listeners assume it means something like:

• the computer I recently bought

But it could also mean:

• the computer you recently bought
• the computer he/she recently bought

if the conversation makes that clear.

Because Korean regularly uses noun-modifying clauses before the noun they describe.

In English, we usually say:

• the computer that I bought recently

In Korean, that becomes:

• 새로 산 컴퓨터
• literally: recently bought computer

This is completely normal Korean structure. The descriptive part comes first, and the main noun comes last.

That is why the sentence may feel backward to an English speaker at first, but it is one of the most important patterns in Korean grammar.
