Questions & Answers about doseogwaneseo chaegeul gollayo.

What does 도서관에서 mean?

도서관 means “library,” and 에서 is the location particle that marks where an action happens. So 도서관에서 translates as “at the library.”

Why do we use 에서 instead of 에 here?

Both 에 and 에서 can refer to a place, but:

• 에 marks a static location or destination (“I am at the library,” 도서관에 있어요; “I go to the library,” 도서관에 가요).
• 에서 marks where an action takes place (“I choose a book at the library,” 도서관에서 책을 골라요).

What role does 책을 play in the sentence?

책 means “book.” The particle 을 marks 책 as the direct object of the verb 골라요. Together 책을 골라요 means “(I) choose a book.”

Why is the verb 고르다 conjugated to 골라요?

고르다 is a 르-irregular verb. In the present polite form:

1. Remove 르 from 고르.
2. Add ㄹ to the verb stem, making 골르 → 골르
   • ㄹ = 골ㄹ.
3. Attach -아요 (because the last vowel in the new stem, ㅏ, pairs with -아요). Result: 골라요.
