    Hi, first of all, I would like to thank you for providing us with such great lessons. It really helps a lot in understanding the language.

    I do have a question regarding this lesson, and I hope you can get back to me as soon as possible. In this lesson you talk about the usage of ~면 안 되다 which I luckily understand, but then I came across the usage of ~면 되다 and I was wondering how I should translate that. It doesn’t seem to be the exact opposite since you talked about that in lesson 4.8.

    Another question I have is about the material discussed in lesson 4.11, in whoch 아무+나=아무나 which means anybody, etc. Well again I came across other words which I do not know how to translate, like 너무+나=너무나 or 언제+나=언제나. I really hope you can help me with this.

    With kind regards,

    • Greg

      Actually they are the opposite. What was in 4.8? 해도 되다? The difference is small, but one maybe more common in certain situation, It’s like literally: “it’s okay if I do like this” (이러면 되다) and “it’s okay even if I do like this” (이래도 되다), like there’s might be other way… slight nuance difference. 이러면 = 이렇게 하면, 이래도 = 이렇게 해도

      너무나 is same as 너무, that’s all I know :D
      언제나 is always/ever, also 누구나 anyone, and 얼마나 well you know (a bit unrelated).

  • Sara


    Thank you Greg for your very quick reply. Just to make sure that I understand it now. One of the examples in this lesson was:

    1. 열다 [yeol-da] = to open
    열면 안 돼요. [yeol-myeon an dwae-yo.] = You shouldn’t open it. You are not supposed to open it.
    (Opposite: 열어도 돼요. [yeo-reo-do dwae-yo.] = It’s okay to open it. You can go ahead and open it.)

    Does this mean that I if I say 열면 돼요. = It’s okay to open it. You can go ahead and open it.

    If so, does that mean that ~도 되다 and ~면 되다 are interchangable?

    So 앉아도 돼요 = 앉으면 돼요 = It’s okay to sit down.

    I hope it’s not too much trouble to reply again.

    With kind regards,

    • Derick

      I think if you say 열면 돼요 it kinda means ” If you open it, its ok. Just my thoughts, dont take my word for it (:

  • Wawa Tonahun

    Very thank to you dear teachers
    Wanna you be happy always for your well done to us
    But I have a little question …*
    You said the structure is: Verb stem + -(으)면 안 되다
    But in all examples you shown to us doesn’t have Verb stem + -(으)
    Can you show me its usage with -(으) Please
    Thank you ^_^

    • Daniel

      In case the verb stem ends in a consonant other than ㄹ, you add 으 before 면 for the ease of pronunciation.

      먹다 – to eat

      이것 먹으면 안 돼요. – You shouldn’t eat this.

    when I saw this lesson I get confused about when I should use 으면 or 면 is it still about the final letter of the verb stems concenent I use 으면 and vowel I use 면 and that means that 열면 is an exception here or there is another rule I don’t know ……

    • Seokjin Jin

      Basically, this pattern also follow the conjugation rule like we used to make the verb to present tense. It is good to make some example sentences through comment. I will try to correct it. :)
