Questions & Answers about gageeseo sae oseul saseo doneul da sseo beoryeosseoyo.

Why is 가게에서 using 에서 and not 에?

에서 marks the place where an action happens (a “location of activity”). Here, the action 사다 (to buy) happens at the store, so 가게에서 = at the store (where you did the buying).
에 is more for destination/existence/time (e.g., 가게에 가요 = go to the store, 가게에 있어요 = be at the store).

What does 새 mean here, and is it the same as 새로운?

새 means new and is an attributive (adnominal) form commonly used before nouns: 새 옷 = new clothes.
새로운 also means new, but it’s a descriptive verb (새롭다) in its modifier form: 새로운 옷. Both are correct; 새 옷 is shorter and very common.

Why is it 새 옷을 with 을?

을/를 marks the direct object of the verb. The thing being bought is 새 옷, so it takes 을 (because 옷 ends in a consonant).
If the noun ended in a vowel, you’d use 를 (e.g., 바지를).
