My Korean Grammar & Usage Note #8: -아/어도 되다 It is alright to…

01 Form

We use -아/어도 되다 to give or to ask for permission to do something.
First, change the verb into the present -아/어요 pattern and replace 요 with 도 되다.

02 Negative Form

We use -(으)면 안 되다 to refuse to give permission or to express prohibition of an action.
If the verb stem ends with a vowel (no batchim), -면 안 되다 is added.

받침 (batchim) is the consonant which added below a normal syllable.
