Questions & Answers about bameneun keopireul masiji malgo mureul masyeoyo.

Why is it 밤에는 instead of just 밤에?

밤에 means at night.
Adding 는 makes it 밤에는, which adds contrast or topic emphasis.

So 밤에는 can feel like:

• as for at night
• at night, though
• when it comes to nighttime

In this sentence, it suggests a contrast such as:

• At night, don’t drink coffee; drink water.
• (Maybe in the daytime it is different, but) at night, drink water instead.

So 에는 here is 에 + 는.

What exactly does 는 do in 밤에는?

The 는 is the topic/contrast marker.

It often does one of these jobs:

• marks the topic of the sentence
• adds a contrastive feeling
• highlights a specific situation

Here it strongly sounds contrastive. The speaker is not just saying something happens at night; they are saying when it is night, this is what you should do.

Compare:

• 밤에 커피를 마시지 말고 물을 마셔요. = At night, don’t drink coffee; drink water.
• 밤에는 커피를 마시지 말고 물을 마셔요. = At night, specifically, don’t drink coffee; drink water.

The second one feels more like a rule or recommendation for that time.

Why are both 커피를 and 물을 marked with 를?
