Questions & Answers about gichayeogeseo pyoreul sayo.

What does 기차역에서 mean and how is it different from using 기차역에?

기차역에서 breaks down into 기차역 (train station) + 에서, the location marker used for actions. It means “at the train station,” emphasizing that the action (buying) happens there.

• 기차역에 would use 에, which often indicates a destination or static location (“to the train station” or “at the train station” when describing existence). If you said 기차역에 가요 (“I go to the train station”), 에 is correct. But for “buying” at that place, you need 에서.

Why is 표를 marked with 를?

를 is the object particle in Korean, marking 표 (ticket) as the direct object of the verb 사요. The pattern is:
Subject + (Location) + Object를 + Verb.
Here, 표를 사요 literally means “buy a ticket.”

How is the verb 사요 formed from 사다, and what level of politeness does it convey?

• 사다 is the dictionary (infinitive) form meaning “to buy.”
• To make a polite present-tense statement, you replace 다 with 요, giving 사요.
  This is the -요 polite style (also called 반말이 아니라 polite 해요체). It’s suitable for everyday polite conversation with strangers or acquaintances.
