Will it be sunny tomorrow?
Did I answer the question correctly?

When people start worrying about something, they cannot concentrate on anything else.

In this article, let’s try to express that concern in Korean.

Express what you are concerned about.

Speak out your doubts and questions.

-ㄹ까 is used when you want to put into words what you are wondering or wondering about.

Speak up about your concerns and questions?

이러면 양이 부족할 거예요.
I don’t think this is enough quantity.


이러면 양이 부족할까요?
Would this be insufficient?

Speak as a question.

The key is to express your doubts and concerns, not to talk about what you think or guess.

How to use “-ㄹ까”.

-ㄹ까 is used with verbs or adjectives.

Vst + -(으)ㄹ까

오다 + -ㄹ까 = 올까
이다 + -ㄹ까 = 일까
내리다 + -ㄹ까 = 내릴까
운동하다 + -ㄹ까 = 운동할까

좋다 + -ㄹ까 = 좋을까
있다 + -ㄹ까 = 있을까
없다 + -ㄹ까 = 없을까

듣다 + -ㄹ까 = 들까
놀다 + -ㄹ까 = 놀까
덥다 + -ㄹ까 = 더울까

※Vst = stem of verbs or adjectives.

Add -ㄹ까 to the stem of a word without a patchum and -을까 to a word with a patchum.

No patchum in the stem

그는 약속 시간에 올까요?
Will he come at the appointed time?
내일은 비가 내릴까요?
Will it rain tomorrow?
민경씨는 내일 잘 일어날까?
I wonder if Mr. Mingyong will wake up properly tomorrow?

If -요 is added to the end of a sentence, it is polite, if not it is an inquiry to someone close to you or to yourself.

Have a patchum in the stem

주말의 강원도는 날씨가 좋을까요?
Is the weather good in Gangwon-do for the weekend?
이 시간에 집에 있을까?
Will he be home at this time?
정말 맛이 없을까?
Are they really not tasty?

You can raise the issue with someone else, or you can talk to yourself.

Cases of irregular changes.


이 문제는 어떻게 풀까요?
How do I solve this problem?

Since there is already a ㄹ-pachym in the stem, only -까 is added.

Part of ㄷpatchum

거기까지 얼마나 걸을까요?
How long will we walk there?

For words where the ㄷ patchm changes to ㄹ, add -을까 after the change.

Part of ㅂpatchum

올 여름이 작년보다 더울까?
Will this summer be hotter than last year?

The vocabulary where the ㅂ patchum changes to 우 is added -ㄹ까 at the point of change.

Let’s try a little application of “-ㄹ까”.

You are willing to talk about your past.

Sometimes what you are concerned about is “in the past”.

서류가 무사히 접수됐을까요?
Would the documents have been accepted successfully?
이번 학기 논문심사에 합격했을까?
Would I have passed my thesis review this semester?
2차대전 때 사람들이 얼마나 고생했을까요?
How hard were people working during WWII?

If you are going to use it with the past tense, add it to -았/었/였.

You can ask for their opinion.

-ㄹ까 can also be used to ask for the other person’s opinion or thoughts.

그 식당이 사람이 많을까요?
Is that restaurant full of people?
오늘은 많지 않을 거예요.
I don’t think there will be many people there today.

It is a good idea to practice answering a question asked with -ㄹ까 with -ㄹ 거예요.

There is also a way to combine them with interrogative word.

You can also add -ㄹ까 to question words such as 무엇.

대체 여기가 어디일까요?
Where in the world am I?
과연 이유가 뭘까요?
What is the reason?
지금은 후쿠오카의 날씨가 어떨까요?
How is the weather in Fukuoka now?

뭐 and 어떻다 are often used with -ㄹ까, so it is good to learn it as one of the patterns.

Once you have learned the basic sentence patterns, let’s actively incorporate them into your conversations with your friends.
