Ce que tu vas apprendre

Ready to take your Korean conversations to the next level? In this chapter, we're diving deep into expressions that will make you sound incredibly natural and confident, moving beyond basic statements to truly express nuances about abilities and actions. First up, you'll master how to use '-(으)ㄹ 줄 알다/모르다' to express 'knowing how to do something' – it's more than just being physically able; it's about skill and know-how. Then, we'll explore the flip sides of difficulty: with '-기 쉽다', you'll effortlessly say something is 'easy to do', and its counterpart, '-기가 어렵다', will equip you to describe tasks that are 'difficult or tricky'. These two are essential for giving your opinions on various activities. Ever found yourself in a situation where something is absolutely impossible? You'll learn '-(으)ㄹ 수가 없다' to convey total impossibility due to circumstances, giving your Korean a powerful punch. Finally, to add precision and emphasis, we'll tackle '-기만 하다', allowing you to highlight when someone is 'doing nothing but' a specific action, showing intense focus. Imagine telling a Korean friend, 'I know how to cook Korean food!' or 'It's impossible to find good coffee here after midnight.' Or perhaps you want to describe how 'studying grammar is easy' or 'writing essays is difficult.' You'll even be able to say, 'He just keeps watching Netflix!' By the end of this chapter, you won't just communicate actions; you'll express capabilities, assess task difficulty, state impossibilities, and emphasize single-minded focus with ease. Your Korean will become richer, more expressive, and you'll feel much more comfortable in intermediate conversations. Let's get started!

Guide du chapitre

Overview

Welcome to a pivotal chapter in your Korean grammar journey! As you progress to B1 Korean, you're ready to add depth and nuance to your conversations. This chapter is designed to help you express not just what you do, but *how* you do it, *how easy or difficult* it is, and even when something is utterly impossible.
Mastering these expressions will make your Korean sound incredibly natural and confident, allowing you to move beyond basic statements and truly articulate your thoughts with precision.
We'll dive into five essential grammar patterns. First, you'll learn -(으)ㄹ 줄 알다/모르다 to confidently state whether you
know how to do something
– highlighting skill and know-how. Next, we'll equip you with -기 쉽다 and -기가 어렵다 to effortlessly describe tasks as easy to do or difficult to do, perfect for sharing your opinions.
For those moments when an action is completely out of reach, -(으)ㄹ 수가 없다 will empower you to convey total impossibility due to circumstances. Finally, to add emphasis and focus, we'll explore -기만 하다, allowing you to highlight when someone is doing nothing but a specific action. By the end, you'll be expressing capabilities, assessing difficulty, stating impossibilities, and emphasizing actions with ease, making your B1 Korean richer and more expressive.
Let's unlock these powerful tools!

How This Grammar Works

Let's break down each of these crucial Korean grammar patterns to understand how they function and how you can use them in your daily conversations.
1. Knowing How to Do Something (-(으)ㄹ 줄 알다/모르다)
This pattern is used to express whether you
know how to do
a specific skill or task. It refers to learned ability or know-how, not just physical capability.
* Conjugation:
* If the verb stem ends in a consonant: verb stem + -을 줄 알다/모르다
* If the verb stem ends in a vowel or ㄹ: verb stem + -ㄹ 줄 알다/모르다
* Example: 저는 한국어를 할 줄 알아요. (I know how to speak Korean.)
* Example: 김치찌개를 만들 줄 몰라요. (I don't know how to make kimchi stew.)
2. Easy to do (-기 쉽다)
Use this pattern to describe an action as easy to do or prone to happen.
* Conjugation: verb stem + -기 쉽다
* Example: 이 책은 읽기 쉬워요. (This book is easy to read.)
* Example: 요즘은 감기에 걸리기 쉬운 날씨예요. (Lately, it's weather where you easily catch a cold.)
3. It is difficult to... (-기가 어렵다)
This is the opposite of -기 쉽다, used to express that an action is difficult to do or hard to achieve.
* Conjugation: verb stem + -기가 어렵다 (The particle 가 can sometimes be omitted in casual speech but adds clarity.)
* Example: 한국어 발음은 하기가 어려워요. (Korean pronunciation is difficult to do.)
* Example: 그 문제를 풀기 어렵다. (That problem is difficult to solve.)
4. Cannot possibly: Total impossibility (-(으)ㄹ 수가 없다)
This pattern conveys a strong sense of impossibility due to external circumstances or conditions, not just a lack of ability. It's stronger than simply using 못 or -지 못하다.
* Conjugation:
* If the verb stem ends in a consonant: verb stem + -을 수가 없다
* If the verb stem ends in a vowel or ㄹ: verb stem + -ㄹ 수가 없다
* Example: 너무 바빠서 만날 수가 없어요. (I'm too busy to possibly meet you.)
* Example: 이 시간에는 택시를 잡을 수가 없어요. (At this hour, it's impossible to catch a taxi.)
5. Doing Nothing But... (-기만 하다)
This pattern emphasizes that someone is doing nothing but a specific action, often highlighting single-minded focus or, at times, a slightly negative connotation if other actions are expected.
* Conjugation: verb stem + -기만 하다
* Example: 그는 하루 종일 게임만 하기만 해요. (He just plays games all day long.)
* Example: 비가 오기만 해서 나갈 수 없었어요. (It just kept raining, so I couldn't go out.)

Common Mistakes

  1. 1✗ Wrong: «저는 수영할 수 알아요.» (I can swim know.)
✓ Correct:
저는 수영할 줄 알아요.
(I know how to swim.)
*Explanation:* -(으)ㄹ 수 있다 means can (possibility/ability), while -(으)ㄹ 줄 알다 specifically means know how to (a learned skill). Don't mix them up!
  1. 1✗ Wrong: «이 음식은 만들기가 쉬워요.» (This food is easy to make.)
✓ Correct:
이 음식은 만들기 쉬워요.
(This food is easy to make.)
*Explanation:* While -기가 어렵다 often uses the particle 가 for clarity, -기 쉽다 typically attaches directly to the verb stem without 가.
  1. 1✗ Wrong: «배고파서 먹을 수 없어요.» (I'm hungry, so I can't eat.)
✓ Correct:
배고파서 먹을 수가 없어요.
(I'm so hungry that I can't possibly eat.) (Or «배고파서 못 먹어요» for simple inability)
*Explanation:* -(으)ㄹ 수가 없다 implies a strong, often external, impossibility. If you simply mean "I can't" due to lack of ability or simple refusal, 못 or -지 못하다 are usually sufficient and more natural. Use -(으)ㄹ 수가 없다 when the circumstances truly make it impossible.

Quick FAQ

Q

What's the difference between -(으)ㄹ 수 있다 and -(으)ㄹ 줄 알다 in Korean grammar?

-(으)ㄹ 수 있다 expresses general ability or possibility (can do), while -(으)ㄹ 줄 알다 specifically means

to know how to do
a learned skill or method.

Q

Can -기 쉽다 and -기가 어렵다 be used with adjectives?

No, these patterns attach only to verb stems to describe the ease or difficulty of performing an *action*.

Q

When should I use -(으)ㄹ 수가 없다 instead of just 못 or -지 못하다?

Use -(으)ㄹ 수가 없다 when emphasizing that an action is *impossible due to external circumstances* or a strong reason, not just a simple inability. It conveys a stronger sense of impossibility.

Cultural Context

These Korean grammar patterns are incredibly common in daily conversations, reflecting how Koreans often discuss skills, challenges, and limitations. -(으)ㄹ 줄 알다/모르다 is frequently used when asking about or offering help with practical skills like cooking, driving, or using technology. -기 쉽다 and -기가 어렵다 are perfect for sharing opinions on tasks, food, or learning experiences, often softening direct statements.
-(으)ㄹ 수가 없다 is a polite but firm way to state an impossibility, often used to decline requests or explain unavoidable situations. Finally, -기만 하다 can be used humorously or to subtly express frustration about someone's single-minded focus. Mastering these patterns will make your Korean sound much more authentic and relatable.

Conseils et astuces (4)

💡

La règle de la modestie

Si on te demande si tu parles coréen, répondre «할 줄 알아요» sonne plus modeste et naturel que «할 수 있어요».
frontend.learn_grammar.from_rule: Savoir comment faire quelque chose (-(으)ㄹ 줄 알다/모르다)
💡

L'opposé direct

Pour dire que c'est 'difficile à faire', remplace juste 쉽다 par 어렵다 : «배우기 어렵다».
frontend.learn_grammar.from_rule: Facile à faire (-기 쉽다)
💡

Zappe la particule

À l'oral, on laisse souvent tomber le «가». C'est beaucoup plus naturel de dire : «찾기 어려워요.»
frontend.learn_grammar.from_rule: Il est difficile de... (-기가 어렵다)
🎯

La pause dramatique

Pour avoir l'air d'un vrai local quand tu es frustré, insiste sur le '수가' et fais une mini pause après : «진짜... 할 수가 없네!»
frontend.learn_grammar.from_rule: Impossibilité totale : Ne pas pouvoir du tout (-ㄹ/을 수가 없다)

Review Summary

  • Verb Stem + -(으)ㄹ 줄 알다/모르다
  • Verb Stem + -기 쉽다
  • Verb Stem + -기가 어렵다
  • Verb Stem + -(으)ㄹ 수가 없다
  • Verb Stem + -기만 하다

Erreurs courantes

Learners often confuse '수 있다' (can) with '줄 알다' (know how to). Use '줄' when referring to a learned skill.

Wrong: 수영할 수 알아요.
Correct: 수영할 줄 알아요.

While '배우기 어렵다' is sometimes heard, the grammatically standard form for B1 level includes the subject particle '-가' after the nominalized verb.

Wrong: 한국어가 배우기 어려워요.
Correct: 한국어는 배우기가 어려워요.

To express total impossibility or to emphasize 'there is no way I can go,' adding '-가' to '수' is much more natural and emphatic.

Wrong: 바빠서 갈 수 없어요.
Correct: 바빠서 갈 수가 없어요.

Questions fréquentes (6)

-(으)ㄹ 줄 알다 se concentre sur la méthode apprise. -(으)ㄹ 수 있다 concerne la possibilité physique. Exemple : «수영할 줄 알아요» (Je sais nager).
En général, non. C'est pour des actions qui demandent un apprentissage. On ne peut pas
savoir comment être beau
grammaticalement. «예쁠 줄 알다» n'est pas utilisé ainsi.
Oui, c'est très courant pour les risques. Par exemple : «오해하기 쉬워요» (c'est facile de mal comprendre).
Enlève juste le «-다» et ajoute «-기 쉽다». Ça marche pour tous les verbes : «먹기 쉽다».
Non, cette structure ne marche qu'avec les verbes d'action. Tu ne peux pas dire 'C'est difficile d'être grand' avec ça.
C'est la nuance clé ! 어렵다 c'est pour la complexité ou le manque de probabilité. 힘들다 c'est pour l'effort physique ou l'épuisement émotionnel. Par exemple : «운동하기가 힘들어요» (C'est épuisant de faire du sport).
