Learn Hardcore Korean: yeonghwagwaneseo haksaeng harineul badayo. - I get a student discount at the movie theater.

에서 marks the place where an action happens. Since 받다 (to receive) is an action, you use 영화관에서.
에 is for static location or destination. Examples:
- 영화관에 있어요. I’m at the theater. (existence)
- 영화관에 가요. I’m going to the theater. (destination)
Saying 영화관에 학생 할인을 받아요 sounds unnatural. Use 영화관에서 with action verbs.

Why is there an object marker 를 on 할인? Can I omit it?

할인 is the direct object of 받다, so the normal form is 학생 할인을 받아요.
In everyday speech, object markers can be dropped: 학생 할인 받아요 (very common and natural).
Don’t confuse with 은/는: 학생 할인은 받아요 means “As for the student discount, I do get it,” implying contrast.

Should 학생 할인 be written with a space? I often see 학생할인.

Both 학생 할인 and 학생할인 are seen. The spaced form is textbook-safe; the solid compound is common on signs/ads.
With the verb, both 할인을 받다 and the compound 할인받다 are standard. No real meaning difference.
So you might see: 학생 할인을 받아요 / 학생할인을 받아요 / 학생 할인받아요 / 학생할인받아요 (all acceptable).

Is “할인을 받아요” the most natural way to say this? What about 할인돼요 or 할인해 주세요?

할인을 받아요: “I receive a discount” (neutral and very common).
할인돼요: “A discount is applied/available.” Often used to ask: 학생 할인돼요? “Do you offer a student discount?”
할인해 주세요 / 할인 적용해 주세요: Polite request to a clerk: “Please apply the discount.”
Casual bargaining (markets, not movie theaters): 깎아 주세요 “Please give me a price cut.”

What politeness level is 받아요? What are alternatives?

받아요 is the standard polite spoken style (해요체).
More formal: 받습니다.
Casual/informal with friends: 받아 (plain) or 받아? (question).
Very polite request (to someone else): 받으세요—but don’t use honorifics for yourself.

Where is the subject “I”? Do I need to say 저는?

Korean often omits obvious subjects. Here, “I” is understood from context.
You can add a subject for clarity or contrast:
- 저는 영화관에서 학생 할인을 받아요. (As for me, I get a student discount at the theater.)
- 우리는… if you mean “we.”

What does the tense/aspect of 받아요 express? Habitual or right now?

받아요 is non-past and can mean habitual/general present (“I usually get…”) or immediate present depending on context.
To emphasize an ongoing action right now: 받고 있어요.
Past: 받았어요. Future/intention: 받을 거예요. Ability: 받을 수 있어요 (“can get”).

Can I move the words around in this sentence?

Yes, Korean word order is flexible as long as particles are clear. Examples:
- 영화관에서 학생 할인을 받아요. (original)
- 학생 할인을 영화관에서 받아요.
- For contrast: 영화관에서는 학생 할인을 받아요.
Avoid 영화관에 학생 할인을 받아요 (wrong particle for an action).

How do you pronounce the sentence naturally?

Why is there no space between 영화관 and 에서?

Case particles like 에서, 에, 을/를, 은/는, 이/가 attach directly to the preceding noun with no space.
So 영화관에서 is correct; 영화관 에서 is incorrect.

Is 영화관 the same as 극장?

영화관 specifically means “movie theater/cinema.”
극장 can mean “theater” in general (plays, musicals), but in everyday speech it’s also widely used for movie theaters. Both are fine in this sentence.

How can I add details like “with my student ID,” “only at the theater,” or “also”?

Instrument/means: 학생증으로 학생 할인을 받아요. (I get the student discount with my student ID.)
“Only”: 영화관에서만 학생 할인을 받아요.
“Also”:
- Location: 영화관에서도 학생 할인을 받아요. (I also get it at the theater.)
- Object: 학생 할인도 받아요. (I also get a student discount—among other discounts.)

Can I just say 할인을 받아요 without 학생?

Yes. 할인을 받아요 means “I get a discount,” but it doesn’t specify that it’s a student discount.
If the context already established it’s a student discount, omitting 학생 is fine.
