Questions & Answers about jeoneun teukhi jumare doseogwaneseo gongbuhaeyo.

What does the particle 는 in 저는 do? How is that different from 제가?

• 는/은 marks the topic: it sets up “as for me” and can imply mild contrast or a general/habitual statement.
• 가/이 marks the grammatical subject and often highlights or identifies the doer as new/important information.
• In this sentence, 저는 sounds natural because you’re making a general statement about your own routine. 제가 특히 주말에… would sound like you’re answering “Who studies at the library on weekends?” with “I do.”

Why is it 주말에 but 도서관에서? When do I use 에 vs 에서?

• 에 marks time points and static locations: 주말에 (on weekends), 도서관에 있어요 (I’m at the library).
• 에서 marks the location where an action happens: 도서관에서 공부해요 (I study at the library).
• So we use 주말에 (time) and 도서관에서 (place of action).

Can I say 도서관에 공부해요?

No. With action verbs like 공부하다, use the place-of-action marker 에서: 도서관에서 공부해요.
Use 에 with motion or existence: 도서관에 가요 (I go to the library), 도서관에 있어요 (I’m at the library).

What exactly does 특히 modify here, and can I move it?
