[Learn Korean I11] -(으)ㄹ지, -는데요, -는걸요

안녕하세요. 토미입니다.

Let’s have fun learning Korean!

Today’s grammar is

-(으)ㄹ지 “if, whether,” 
② -는데요
it is ~, isn’t it?
③ -는걸요
because.” 

After you learn today’s grammar, when you are a big fan of a celebrity, and he talks to you, 왜 그렇게 저를 좋아하세요? “Why do you like me so much?” then you can tell him something like 

오빠가 너무 좋은걸요! 

“Because I love Oppa so much!”

Wow! If you reach this level, the celebrity Oppa you love will be surprised at your advanced Korean!

Let’s surprise those native speakers with advanced expressions, pass TOPIK II, and be the super master of Korean!

I’m sure you can do it!

그럼 시작할게요! 

 – (으)ㄹ지

Verbs • Adjectives(without a final consonant) + ㄹ지
Verbs • Adjectives(with a final consonant) + 을지

Nouns + 알지

In the first grammar, you use -(으)ㄹ지 (if, whether) with verbs or adjectives. You use it when you assume something uncertain.

In most cases, Korean people use this grammar as -(으)ㄹ지 모르다 “to be uncertain if.” -(으)ㄹ지 걱정이다 “to be worried if” and -(으)ㄹ지 정하다 “to decide if.”

So, please put the whole phrase in your mind. In addition, Korean people pronounce 지 in -(으)ㄹ지 in a tense sound as 찌, so please pay attention to that as well.

Then, let’s look at its conjugation to verbs, adjectives, and nouns.

Verbs • Adjectives:  First, conjugations are the same for verbs and adjectives, so we are mainly looking at verbs for now.

If a verb stem has no final consonant, add -ㄹ지. For example, 가다 “to go” does not have a final consonant, so you add -ㄹ지 to make 갈지 “If I go.”

If a verb stem has a final consonant, you add -을지.

For example, 먹다 “to eat” has a final consonant, so you add -을지 to make 먹을지 “if I eat.”

Nouns: You use -일지 regardless of a final consonant for nouns.

Therefore, 무료 becomes 무료일지 “if it’s free,” and 학생 becomes 학생일지 “if he/she is a student.” 

Then, let’s look at some examples.

Verbs: Example 1
오빠가 약속 시간에 도착할지 걱정이에요.
I am worried that Oppa will arrive at the appointed time.

Here, 도착하다 “to arrive” is a verb without a final consonant, so you add -ㄹ지 to make 도착할지 “If he comes.”

In addition, it is used with 걱정이에요, so the whole phrase becomes 도착할지 걱정이에요 “I am worried if (he) arrives.”. 

Let’s move on to the following example.

Adjectives: Example 2
여름에 여행을 가려고 하는데 어디가 좋을지 어떻게 정하지?.
I am considering going on a trip in the summer, but how should I decide which place is good to go to?

Here, 좋다 “to be good” is an adjective with a final consonant, so you add -을지 to make 좋을지 “If it’s good.”

In addition, after this grammar, 정하지? “decide” follows to make a phrase like 어디가 좋을지 어떻게 정하지 “how should I decide which place is good.”

Let’s see the last example. 

Nouns: Example 3
어느 게 더 좋은 방법일지 저는 잘 모르겠어요.
I don’t know which one is the best way.

Here, 방법 a “way(means)” is a noun, so you add -일지 to make 방법일지 “if it is a (better) way.”

In addition, 모르겠어요 “I don’t know” follows this grammar to make 방법일지 모르겠어요 “(I) don’t know which one is a better way.”.  

Quiz

Then, let’s deepen our understanding with some quizzes. Which one is the correct answer? 

1. 친구한테 선물하려고 샀는데 (                ) 모르겠어.

“I bought it to give to my friend, but I don’t know if he would like it.”

 (1)마음에 들지 (2)기에 들어갈지 

The correct answer is number one.

마음에 들다 is “to like.” 들다 has a final consonant of ㄹ, so you directly add 지 모르겠어 to make 마음에 들지 모르겠어 “I don’t know if (he) would like it.”

Number two is the wrong answer because 기에 들어갈지 itself is a bad expression. 

Then, let’s read it together, shrugging shoulders.

친구한테 선물하려고 샀는데 (마음에 들지) 모르겠어.

Please read it at least three times. Then, let’s move on to the following quiz.

 

2. 열심히 공부했는데 시험에 (                ) 걱정되네요.

I studied hard, but I am worried about whether I will pass the exam. 

(1) 합격할지 (2) 잘 될지  

The correct answer is number one.

합격하다 is “to pass (an exam).” You add -ㄹ지 걱정되네요 to make 합격할지 걱정되네요 “I am worried whether I will pass.”.

Number two is the wrong answer because there is no expression like 시험에 잘 되다, so please be careful.

If you chose this one, maybe you were confused with 시험을 잘 보다, which is “to turn out well on an exam.” 

Then. Let’s read it with a touch of anxiety!

열심히 공부했는데 시험에 (합격할지) 걱정되네요.

Please read it at least three times. OK? 

 -는데(요) 

Verbs + 는데(요)

Adjectives(without a final consonant) + ㄴ데(요)
Adjectives(with a final consonant) + 은데(요)

Nouns + 인데(요)

Next, let’s look at the second grammar.

As I told you in the beginner class, -는데 is a conjunctive form that connects sentences and means “even though / though.”

Hmm, then why are we learning about it again?

Yeah, I hear you. 

I will tell you this time that the ending expression is mainly used in 

conversation. After you master it, you will sound much more like a native Korean.

Today, we are learning two meanings of -는데(요).

First, express your surprise at something unexpected by saying, “Wow! I am surprised by that/ it is something, isn’t it? ”

The second one is to ask a question for some explanation, like “What is the reason?” or “Why are you asking?”

In this case, Korean people often use interrogative words such as 무엇 (what), 누구 (who), 언제 (when), and 어디 (where).

About the conjugation, for verbs, you use -는데(요); for adjectives, you use -(으)ㄴ데(요); and for nouns, you use -인데(요).

However, since this grammar is colloquial, Korean people often omit 이 from -인데요 to make 최곤데요 “Wow! It’s the best,” 언젠데요 “Wow! When is it?”

 

Then, let’s look at 는데 in pattern two, asking questions.

Verbs: Example 1
가 : 난 내일 아침에 빨리 나가야 돼서 먼저 잘게.
I must go out early tomorrow morning and go to bed first.

나: 어, 몇 시에 나가는데?
Oh, what time are you going out?

In this sentence, you use this grammar to ask for an explanation about “what time are you going out?” Right?

Here, 나가다 “to go out” is a verb, so you add -는데 to make 나가는데 “go out?”

Then, let’s look at some examples from pattern one, such as when you get surprised at something unexpected.

Adjectives: Example 2
와, 오늘 날씨가 굉장히 더운데.
Wow, today the weather is hot, isn’t it?

Here, you can express your feelings about the unexpected hot weather by using -(으)ㄴ데(요). 

In this sentence, 덥다 “to be hot” is an adjective with ㅂ final consonant, so you add -은데.

However, for 덥다, you have to apply ㅂ irregular, don’t you?

So you will change this to 우 to make 더운데 “Wow, it’s hot, isn’t it?”

The following example is also in pattern two, asking questions.

Nouns: Example 3
가: 이거 좀 봐 봐.
Take a look at this.

나: 아니, 이게 뭔데요?
Um, what is this?

In this sentence, the speaker 나 is trying to ask for an explanation like “What is it?”

You treat 뭐 “뭐” as a noun, so you add -인데, but 이 is omitted, and it becomes 뭔데요 “what is it?”

This is a very colloquial expression. 

Quiz

Okay. Then, let’s deepen our understanding with some quizzes.

Which one is the correct answer? 

 1. 이 영화 정말 (                   )!
This movie is entertaining, isn’t it?

 (1)재미있는데요 (2)대박난데요 

The correct answer is number one.

You want to say that the movie was unexpectedly entertaining, so it’s pattern one.

재미있다 is “to be entertaining,” and it is an adjective.

However, the ending of the word is -있다, so you conjugate it as a verb -는데(요).

Here, you have to speak politely, so you add 요 as well to make 재미있는데요 “(this movie) is entertaining, isn’t it?”

The number two is wrong because 대박나다 means “to be a big hit.”

But Korean people love this word, so please memorize it, too!

Then, let’s read it like you are telling your friend how entertaining the movie was!

이 영화 정말 (재미있는데요)!

 

Please read it at least three times. Then, let’s move on to the following quiz!

2. 왜 아무도 없을까? 정말 (                  ).
“Why is there nobody? It is quite strange, isn’t it?”

 (1)이상하는데 (2)이상한데 

The correct answer is number two.

It sounds like he is talking to himself, right?

Here, 이상하다 is “to be strange,” and it is an adjective without a final consonant.

So, you use -ㄴ데(요).

Here, you want to say it casually with 반말, so you make the phrase 이상한데.

Number one is wrong because there is no such expression as 이상하는데, so please be careful. 

Then, let’s read it, imagining you are a police officer who went to a crime scene.

왜 아무도 없을까? 정말 (이상한데).

Please read it at least three times.

-는걸(요)

Verbs + 는걸(요)

Adjectives(without a final consonant) + ㄴ걸(요)
Adjectives(with a final consonant) + 은걸요

Nouns + 인걸(요)

Let’s look at the last grammar! -는걸(요) has two different meanings.

One is to tell your surprise or admiration about something you get to know.

The other one is to tell your opinion lightly, saying “it is because ~” or to argue against someone’s opinion lightly.

This “lightly” is the important point here.

For verbs, you use -는걸(요); for adjectives, you use -(으)ㄴ걸(요); and, for nouns, you use -인걸(요).

Besides, when you speak politely with the honorific ending 요, the pronunciation constantly changes to [걸료], never being pronounced [거료]. 

Then, let’s look at the example of the first meaning: to tell your surprise or admiration for something you get to know.

Verbs: Example 1
날씨가 점점 추워지는걸.
The weather is getting colder and colder.

Here, you want to express your surprise at something new: the weather getting colder.

In this sentence, 추워지다 “to get cold” is a verb, so you add -는걸 to make 추워지는걸 “it is getting colder.” The following sentence exemplifies the second meaning: lightly telling your opinion to the other person.

Then, please look at this.

Adjectives: Example 2
가: 혼자 다 할 수 있겠어요?
Can you do all of it alone?

나: 괜찮아요. 이 정도는 아무렇지도 않은걸요.
It’s okay. This amount of things is not a big deal.

Here, the speaker is lightly telling his/her opinion, saying, “It’s not a big deal.”

아무렇지도 않다 “to be not a big deal” is an adjective with a final consonant, so you add -은걸요 to make 아무렇지도 않은걸요 “It’s not a big deal.”

 And 아무렇지도 않다 is a valuable expression meaning “not a big deal,” so please keep it in mind.

The following sentence also tells an opinion lightly. Let’s look at it together. 

Nouns: Example 3
가: 도와줘서 정말 고마워요.
Thank you so much for helping me out.

나: 아니에요. 당연히 해야 할 일인걸요.
No worries. It is, of course, what I should do.

Here, it is used to give an opinion on what the other speaker said, saying, “It’s what I should do.”

In this sentence, 일 “thing” is a noun, so you add -인걸요 to make 일인걸요 “It is a thing that I should do,” which means “It is what I should do.”

Quiz

Then, let’s deepen our understanding with some quizzes.

Which one is the correct answer? 

1. 물이 꽤 (                  ).
The water is quite cold.

(1)차가운걸 (2)차가운껄

The correct answer is number one.

차갑다 is “to be cold.” 차갑다 is an adjective with a final consonant, so you use -ㄴ걸. Also, 차갑다 is a ㅂ irregular word.

So, you make 차가운걸. OK? 

Number two is wrong because 차가운껄 does not even exist, so please be careful.

Then, let’s imagine you are surprised at the cold water when you go into a pool and read the sentence together.

물이 꽤 (차가운걸).

Please read it at least three times.

Let’s move on to the following quiz, which is a dialogue.

2. 가: 배고프지? 뭘 만들어 줄까?
You must be hungry. Do you want me to cook something for you?

나: 괜찮아요. 냉장고 안에 먹을 게 얼마든지 (                    ).
I’m okay. Because there is plenty of food in the fridge.

(1)있는걸요 (2)있는걸료

The correct answer is number one.

있다 is “there is,” which has a final consonant.

As I said before, you modify 있다 as a verb.

Therefore, you attach -는걸요 to the stem to make 있는걸요 “there is something.”

The second answer is correct regarding its pronunciation, but we never write it this way.

So please keep that in mind.

Then, let’s read it together like you say, “You don’t have to worry about me.”

냉장고 안에 먹을 게 얼마든지 (있는걸요).

Please read it at least three times. OK? 

 Homework

Yes! It’s about time to give you homework that you guys love!

나는요, 학생이 좋은걸!! 어떡해〜!

Because I love these students! Come on, homework!

There are two kinds of homework. First, please write three sentences using the grammar we learned today in the comment section.

For the first sentence, please use -(으)ㄹ지 “if, whether” and write a sentence you would use when you don’t feel confident, like “I don’t know if it’s correct.” For example,

  • 태어나서 처음으로 빵을 구워 봤는데 이게 맛있게 잘 될지 잘 모르겠네요.
    I baked bread for the first time, but I’m unsure if this will come out tasty.

For the second sentence, please use -는데(요) “it is ~, isn’t it?” to make a sentence to tell surprise or admiration at something unexpected.

For example,

  • 중급 공부 생각보다 쉬운데?
    Studying in the intermediate class is more straightforward than expected, isn’t it?

I made this sentence hoping you guys are thinking the same way.

For the third sentence, please use -는걸요 (because) and lightly tell someone your opinion or surprise about some fact.

For example, 

  • 학생들한테 한국어를 가르치는 일이 너무 보람찬 일인걸요!
    Because teaching Korean to students is fulfilling.

OK? 

And thank you, guys, for always submitting homework in the comment section.
