주말에는 is 주말에 + 는.

• 주말에 means on the weekend / at the weekend
• adding 는 makes it a topic and often adds a slight sense of contrast

So 주말에는 책을 많이 읽어요 can feel like:

• As for weekends, I read a lot of books
• On weekends, I read a lot

It may suggest something like on weekends (as opposed to weekdays), I read a lot, even if that contrast is only implied.

In this sentence, 는 is the topic particle.

It tells the listener what time frame the speaker is talking about: when it comes to weekends.

Because it comes after 에, the full form is 에는. This is very common in Korean:

• 학교에 → 학교에는
• 집에 → 집에는
• 주말에 → 주말에는

It does not change the basic meaning of 에; it adds a topic/contrast nuance.

책을 uses the object particle 을/를.

That particle marks what is being read.

• 책 = book / books
• 책을 읽어요 = read a book / read books

Since 책 ends in a consonant, it takes 을 rather than 를.

• consonant ending → 을
• vowel ending → 를

For example:

• 책을
• 영화를

It can mean either book or books, depending on context.

Korean often does not mark singular vs. plural as clearly as English does. In this sentence, because of 많이 and the overall meaning, English will often translate it naturally as books:

• I read a lot of books on weekends

But grammatically, Korean does not need a separate plural marker here.

많이 is an adverb, and in Korean adverbs usually come before the verb they modify.

So:

• 많이 읽어요 = read a lot

This is normal Korean word order. Korean is generally Subject/Topic - Object - Verb, and adverbs usually appear before the verb as well.

It mainly means a lot.

So 책을 많이 읽어요 most naturally means:

• I read a lot
• I read a lot of books

Depending on context, English might sometimes express this with often read, but 많이 is about quantity/degree, not frequency by itself.

If you wanted to emphasize often, Korean would more naturally use something like 자주.

• 책을 많이 읽어요 = I read a lot
• 책을 자주 읽어요 = I read often

Korean very often omits the subject when it is clear from context.

So this sentence does not explicitly say I, but in many situations it naturally means:

• I read a lot of books on weekends

Depending on context, it could also mean:

• we read a lot of books on weekends
• they read a lot of books on weekends

Korean leaves out subjects much more freely than English does.

The dictionary form is 읽다, which means to read.

The sentence uses 읽어요, which is the polite present tense form.

So:

• 읽다 = to read
• 읽어요 = read / am reading / do read

In Korean, the present tense can cover several English present meanings depending on context.

It is commonly pronounced close to 일거요.

This happens because Korean pronunciation changes can make the written form and spoken form look different.

Very roughly:

• 읽어요 → 일거요

You still write it as 읽어요, but when listening, it may sound much closer to 일거요 than what an English speaker might expect from the spelling.

Yes. That is a very natural interpretation.

This sentence usually describes a habit or usual pattern, not just one specific weekend.

So it often means:

• On weekends, I read a lot
• I read a lot on weekends

If you wanted to talk about this weekend specifically, you would usually need different wording and more context.

Yes. In casual speech and writing, 에는 is often contracted to 엔.

So:

• 주말에는 책을 많이 읽어요
• 주말엔 책을 많이 읽어요

These mean the same thing. The shorter version is very common in conversation.

Because Korean usually puts the verb at the end.

A helpful way to look at this sentence is:

• 주말에는 = on weekends / as for weekends
• 책을 = books
• 많이 = a lot
• 읽어요 = read

So the structure is roughly:

• Time/topic + object + adverb + verb

This is one of the biggest word-order differences between Korean and English.
