안녕하세요 여러분! This lesson will cover 2 low-Intermediate level grammar patterns. One is used to say that you "are not allowed to do" something and the other is used to say "It's okay if you do" something. Using this grammar we can also make a double negative. Let's get into the lesson!
V+(으)면 안 되다 = not allowed to, shouldn't, can't
Usage: This grammar is used to say that a certain action should not be done or is not allowed/prohibited. You’ll see it translated as: Shouldn’t, May not, To not be allowed.
How To Conjugate :
> Verb stem ends with a vowel or ㄹ:
보다 - - 보 + 면 안 되다
> Verb stem ends with a consonant:
먹다 - - 먹 + 으면 안 되다
> V-하다 → V-하면 안 되다:
청소하다 -- 청소하면 안 되다
