[Korean Grammar] V + (으)세요 vs V + 아/어 보세요

 

V-(으)세요 vs V-아/어 보세요 / “Please do vs Try doing in Korean”

 Both forms are often translated as “please do…” in English, but the feeling and purpose are different.

 

1. V-(으)세요 = Polite request / instruction

1) Meaning

Used to politely tell someone to do something.
It sounds like a request, suggestion, or instruction from the speaker.

👉 Focus = The action itself

2) Feeling

The speaker believes the listener should do the action.

 

Example, 

문을 닫으세요.	Please close the door.
이 약을 드세요.	Please take this medicine.
여기 앉으세요.	Please sit here.
천천히 말씀하세요.	Please speak slowly.

2. V-아/어 보세요 = Suggest trying something

1)  Meaning

Used to suggest trying an action to see what happens or to experience it.

👉 Focus = The experience or result

2) Feeling

The speaker is saying:

Try it and see. You might find it helpful/good

 

It is softer and less commanding than -(으)세요.

 

Example, 

이 음식을 먹어 보세요.	Try this food.
한국 드라마를 봐 보세요.	Try watching a Korean drama.
이 버튼을 눌러 보세요.	Try pressing this button.
다시 생각해 보세요.	Try thinking about it again.

The listener is free to try, not strongly told to do it.

Main Idea	Please do this / 하세요	Try doing this / 해 보세요
Focus	The action	The experience/result
Strength	More direct	Softer, more like advice
Nuance	Instruction / request	Suggestion / experiment
