Because the two particles are doing different jobs:

• 에 marks a time expression: at/on the weekend
• 는 adds a topic or contrast feeling: as for weekends / on weekends, at least

So 주말에는 feels like:

• on weekends
• as for the weekend
• when it comes to weekends

This is very common in Korean. A time noun can take 에, and then 는 can be added on top of it for emphasis, contrast, or topic marking.

Compare:

• 주말에 = on the weekend
• 주말에는 = on weekends / as for weekends

The second one often sounds a little more like the speaker is talking about a routine or contrasting weekends with other times.

Usually it means on weekends in general or on the weekends as a habit.

So this sentence most naturally suggests a repeated action:

• On weekends, I eat dinner at my parents’ place.

If you specifically wanted to say this weekend, you would normally say:

• 이번 주말에는 = this weekend

Without 이번, the sentence usually sounds habitual or general.

부모님 is the respectful, natural way to say parents in everyday Korean.

• 부모 = parents, but more formal/dictionary-like
• 부모님 = parents, with the honorific 님

Since people usually speak respectfully about their own parents or someone else’s parents, 부모님 is much more common in normal conversation.

So in this sentence, 부모님 sounds polite and natural.

댁 is an honorific word for home/house.

• 집 = house/home
• 댁 = home/house, but respectful

So 부모님 댁 means my parents’ home in a respectful way.

Because the sentence already uses 부모님, using 댁 matches that respectful tone very well.

You could say 부모님 집에서, and people would understand it, but 부모님 댁에서 sounds more polite and natural when referring to your parents’ home.

에서 marks the place where an action happens.

In this sentence, the action is 먹어요 (eat), and that action happens at the parents’ home, so Korean uses 에서:

• 부모님 댁에서 = at my parents’ home

This is different from 에, which is often used for:

• destination
• existence
• location in a more static sense

A useful shortcut:

• 에서 = where an action happens
• 에 = to / at / in, depending on the context, but often not for active action locations

Because eating is an action, 에서 is the correct particle here.

Because 저녁 is the direct object of 먹어요.

• 저녁 = dinner/evening meal
• 을 = object marker
• 저녁을 먹어요 = eat dinner

In Korean, the thing being eaten takes the object particle:

• 밥을 먹어요 = eat a meal / eat rice
• 점심을 먹어요 = eat lunch
• 저녁을 먹어요 = eat dinner

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

In Korean, the present tense often covers habitual actions too, just like English can.

So 먹어요 can mean:

• eat
• am eating in some contexts
• eat regularly / usually eat

In this sentence, because of 주말에는, the meaning is naturally understood as a habitual action:

• On weekends, I eat dinner at my parents’ place.

So even though the form is present tense, the meaning is habitual present, not necessarily something happening right now.

The subject is omitted, which is extremely common in Korean.

The sentence does not explicitly say I, but in many contexts Korean leaves the subject out when it is already understood.

So depending on context, this could mean:

• I eat dinner at my parents’ place on weekends
• We eat dinner at my parents’ place on weekends

However, if this is a standalone example in a textbook, it is most naturally understood as I.

Korean often relies on context instead of stating pronouns every time.

The sentence follows the normal Korean pattern of putting the verb at the end.

Breakdown:

• 주말에는 = on weekends
• 부모님 댁에서 = at my parents’ home
• 저녁을 = dinner
• 먹어요 = eat

So the order is basically:

• time + place + object + verb

That is very common in Korean. The most important thing to remember is that the verb usually comes last.

Yes. 주말에는 is very often shortened to 주말엔 in speech and informal writing.

So these are equivalent:

• 주말에는 부모님 댁에서 저녁을 먹어요.
• 주말엔 부모님 댁에서 저녁을 먹어요.

The shorter form is very common and natural. The full form may feel a bit clearer for learners, but both are correct.

Not in this sentence.

Because the verb is 먹어요, and eating is an action that happens at a location, Korean uses 에서.

• 부모님 댁에서 저녁을 먹어요 = correct

If you said 부모님 댁에, it would sound incomplete or wrong with 먹어요.

You would use 에 with verbs like:

• 가요 = go
• 와요 = come
• 있어요 = exist / be

For example:

• 부모님 댁에 가요 = I go to my parents’ home
• 부모님 댁에 있어요 = I am at my parents’ home

But:

• 부모님 댁에서 먹어요 = I eat at my parents’ home

Yes, it is polite.

There are two main signs of politeness here:

• 부모님 and 댁 are respectful words
• 먹어요 is in the standard polite -어요 style

So the whole sentence sounds natural and polite for everyday conversation.

A more casual version might be:

• 주말엔 부모님 집에서 저녁 먹어.

A more formal version could be made too, but the original sentence is already very appropriate for normal polite speech.
