    Is there no difference between should, must and have in korean?

  • The Deadly Bean

    isn’t it “공부해여야 되요” ? As the 하다 verb stem is followed with -여 야 돼요? Not trying to sound like a know it all but i just wanted to make sure.

    Hello I only found a couple mistakes.
    내일 학교는 시작한을 거예요.그래서 오늘 저는 잘쉬야 돼요 –> 내일 학교는 시작할 거예요.그래서 오늘 저는 잘 쉬어야 돼요

    Remember the rule for future tense is verb stems ending in a vowel are followed by ㄹ 거예요 so 시작하다 –> 시작할 거예요.
    Also it should be 쉬어야 돼요 since the rule is verb stems not ending in vowels ㅏ or ㅗ you add 어야 되다/하다

    To say “I want to go to Korea, but I have to save money first” would be 저는 한국에 가고 싶어요. 그렇지만 먼저 돈 절약해야 돼요

    Also, 먹었었어요 —> 먹었어요
    I’m also learning myself so I could be wrong.

    How do you say “it’s okay to speak Korean?” For example, if the person tries to speak English and the English speaker says “it’s okay you can speak Korean”

    Sorry if you said this, I didn’t quite get it. What is the difference of when you use 야 뒤다 and 야 하다? Like, when would you use 야 뒤다 or 야 하다? Thanks!!

    If “되다” will be turn into “돼요” (되 + 어요) for the present tense, then wouldn’t the past tense be “됐어요” and “됄 가예요” would be the future tense?

  • Amal

  • María Paz

    I’m checking the book and this PDF but both of them only refer to verb stems ENDING in a vowel, how about verb stems ending with a consonant? Like 팔, 살 or 그림?? Is it 팔아야 하다? 팔어야 하다???

    • 우유

      example number 3 uses the verb 있다, which has a verb stem that ends in a consonant 🙂 it became 있어야 돼요. verb stems with the final vowel 아 would use ~아야 돼요, e.g. 살다 has a final vowel of 아, so it would become 살아야 돼요. verb stems with 어 as the final vowel would use ~어야 돼요, e.g. 먹다 > 먹어야 돼요. there aren’t a few rules you’re yet to learn at this stage so even if i explained them for you, you would likely find conjugating difficult. e.g. 돕다 would become 도와야 돼요. at this point in time, it’s easier to stick with what ttmik and I explained 🙂 i hope it helped a little. let me know if you have questions

    • 우유

      there are* a few rules

      lolol whoops sorry

  • Yash Gupta

    2) 저는 지금 일해야 돼요. 그런데 저는 한국어를 공부고 싶어요.
    I have to work now. But I want to study Korean.

    3) 저는 공부해야 돼요. 그런데 저는 기억하는 것을 못 하다.
    I have to study, but I’m not good at remembering.

    I’m pretty sure the sentence no. 3 is wrong, but that’s how it came out of my mind ;(
