Allowed to - 해도 된다

Allowed to - 해도 된다 

Informal Form

Informal
are allowed to
were allowed to
Written
해도 된다
해도 됐었다
Spoken
해도 돼
해도 됐었어

Informal
aren't allowed to
weren't allowed to
Written

하면 안됐었다
Spoken

하면 안됐었어


Note:

해도 돼 means "allowed to do" and 안해도 돼 means "don't have to do," NOT "not allowed to do." This needs some explanations.

First of all, 돼 means "ok or allowed." 해도 돼 literally means "doing is ok." 안해도 literally means "not doing" therefore 안해도 돼 literally means "not doing is ok" which means "don't have to do."

하면 안돼 means "not allowed to do." 하면 literally means "if I do" and 안돼 means "not ok" therefore 하면 안돼 literally means "if I do it, it's not ok" which can be expressed as "not allowed to do"

Compare this with Have to - 해야 한다

However, you don't have to know these explanations to use them. Actually, I've never thought about why these mean what they mean until today. The best way to learn them is to use them frequently until they become memorised.

  1. I really appreciate this guide. It's great to have all these basic Korean grammar rules laid out in one place like this. 고마워요~ (:

    One question though. Isn't 되다 conjugated as "됐어" in past tense? You have it as "됐어".
