Questions & Answers about sueop dwie keopireul masigo sipeoyo.

What does 뒤에 mean in this sentence?

뒤에 literally means “behind,” but when used after a time noun like 수업 (“class”), it functions as “after”. Here, 수업 뒤에 means “after class.”

Why is the time expression 수업 뒤에 placed at the beginning of the sentence?

Korean typically orders sentences as [time/place]–[object]–[verb]. Placing 수업 뒤에 first emphasizes when the action happens. You could also say 저는 수업 뒤에…, but dropping 저는 (the topic) is common when context is clear.

Why do we say 커피를 마시고 싶어요 instead of just 커피 마시고 싶어요?

The particle 를 marks 커피 as the direct object of the verb 마시다 (“to drink”). Omitting 를 in casual spoken Korean can happen, but in standard sentences you include 를:
• 커피를 마시고 싶어요 – “I want to drink coffee.”

What is the function of -고 싶어요?

The grammar pattern -고 싶다 expresses “to want to [verb].” You attach -고 싶어요 to the verb stem to politely say you want to do something.
For example:
• 마시다 → stem 마시- → 마시고 싶어요 = “I want to drink.”

Why is it 마시고 싶어요 and not 마시고 싶다요 or something else?

You take the verb stem 마시-, add -고 to connect, and then add 싶어요 (the polite present form of 싶다). You never say 싶다요; the correct polite ending is -고 싶어요 for statements.

Could I use 후에 instead of 뒤에 after 수업?

Yes. 수업 후에 also means “after class.”
• 뒤에 is more everyday, implying “after/right behind.”
• 후에 is slightly more formal or written.
Both are common:
• 수업 뒤에 커피를 마시고 싶어요.
• 수업 후에 커피를 마시고 싶어요.

Can I change the formality of the sentence?

Certainly. For casual speech, you can use -고 싶어:
• 수업 뒤에 커피를 마시고 싶어.
More formal:
• 수업 뒤에 커피를 마시고 싶습니다.

Why is there no subject like 저는 in front of the sentence?

Korean often omits the subject when it’s understood from context. Adding 저는 is not wrong:
• 저는 수업 뒤에 커피를 마시고 싶어요.
But if it’s clear you’re talking about yourself, you can skip it for brevity.
