Commanding-Allowing – Korean Aspects #4

In this episode, we'll learn how to command or allow other people to do something like "It's okay to do this", "You must not do that", etc.

-아/어도 좋다

It means "it's okay to do something".

지금 가 봐도 좋아.
It's okay to go there now.

틀려도 좋으니까 마음대로 해.
Do whatever you want. It doesn't matter if you do something wrong.

-는 게 좋겠다/낫겠다.

It added "-겠" between 좋다. And the meaning has been changed to "you had better do something" or "how about doing something?", "it will be better for you to do something."

빨리 먹는 것이 좋겠다.
It will be better for you to eat quickly.

다 그만 두고 쉬는 편이 낫겠다.
It should be better for you to quit everything and take some rest.

-(으)렴

It is used when older people ordering something to younger people.

얼른 마시렴.
Drink it quickly.

그만 자고 일어나렴.
Stop sleeping and wake up.

-(으)면 안 되다

It is used when some action is against the rule.

지금 들어가시면 안 됩니다.
You should not enter here now. (It implies that you can enter later.)

다시는 늦으면 안 돼.
Never be late again.

-(으)ㄹ 수 있다/없다

As we learned in our first episode of aspects, -(으)ㄹ 수 있다/없다 are used for abilities. However, our abilities are sometimes restricted by the rules. That's why you can use -(으)ㄹ 수 있다/없다 for rules.

아직은 드실 수 없어요. 조금만 기다려 주세요.
You cannot eat it now. Please wait a bit.

앞으로 3분 동안만 구매하실 수 있습니다. 빨리 오세요.
You can buy it for only 3 minutes from now on. Come here. Quick!

-아/어야 하다/되다

This expression is used for some deadline or rule.

12시 전에는 집에 들어가 봐야 해요.
I should get back home before 12.

오후 3시까지 이 일을 끝내야 된다.
We should finish the work before 3 p.m.
