Remember back in Stage 4 (bg-17) when you learned -(으)세요? We noticed that while it is often used as a polite request (*“Please sit down”*), it also appears in statements like *“선생님이 가세요”* (*The teacher is going*).
Here is the secret you have been waiting for:
-(으)세요 is actually made of two distinct parts: -(으)시- *(honorific infix honoring the subject)* + -어요 *(conversational polite ending)*!
Whenever the SUBJECT of the sentence (the person performing the action) is someone you honor or respect: - Grandparents, parents, teachers, bosses, older relatives, customers, and guests.
Golden Rule: You NEVER use -(으)시- on yourself! (*“제가 가세요”* ❌)
가다 (to go)No batchim · 가세요 · 가십니다 · 선생님이 학교에 가세요.
오다 (to come)No batchim · 오세요 · 오십니다 · 할머니가 집에 오세요.
