How This Grammar Works

This chapter introduces five powerful Korean grammar patterns that will significantly enhance your ability to express uncertainty and ask indirect questions. First up, we have -ㄴ/은/는지 and -는지 (Whether or Not / Indirect Questions: Knowing Who, Where, and If). These versatile endings attach to verbs and adjectives to embed questions within a larger sentence.
Use -는지 for present tense verbs and adjectives ending in a vowel (or -ㄹ), and -은지 for adjectives ending in a consonant, and -ㄴ지 for past tense verbs/adjectives or descriptive verbs. For example, "I wonder if it's open" is 문이 열렸는지 궁금해요 (I'm curious if the door opened). Or,
I know who came
is 누가 왔는지 알아요 (I know who came).
Next, we explore -(으)ㄹ지 (Korean Future Uncertainty: Whether to...), which is perfect for discussing future options or decisions. It attaches to verbs and means
whether to do something
or
if something will happen.
For instance, 내일 갈지 안 갈지 모르겠어요 (I don't know whether I'll go tomorrow or not). This helps express personal indecision.
Then comes -(으)ㄹ지도 모르다 (Expressing Uncertainty: Might or May). This structure is used to express a possibility or a hunch – something might or may happen. It softens statements and indicates a degree of uncertainty.
For example, 비가 올지도 몰라요 (It might rain). It’s excellent for speculating about future events.
Finally, we have -(으)ㄹ까 봐 (Worried That...). This crucial pattern explains an action taken because of a worry or concern. It means
because I was worried that...
or fearing that... For example, 늦을까 봐 택시를 탔어요 (I took a taxi because I was worried I might be late).
Mastering these forms will make your B1 Korean sound incredibly natural and expressive.

Common Mistakes

  1. 1✗ Wrong: 그는 언제 오는지 몰라요. (He doesn't know when he will come.)
✓ Correct: 그는 언제 올지 몰라요. (He doesn't know when he will come.)
*Explanation:* When expressing uncertainty about a *future* action or decision (
whether to do something
), -(으)ㄹ지 is more appropriate than -는지. While -는지 can refer to future in indirect questions, -(으)ㄹ지 specifically emphasizes the future uncertainty or choice.
  1. 1✗ Wrong: 비가 올 것 같아요. (It seems like it will rain.) (When meaning it *might* rain)
✓ Correct: 비가 올지도 몰라요. (It might rain.)
*Explanation:* While -것 같아요 expresses likelihood or appearance, -(으)ㄹ지도 모르다 is specifically for expressing a possibility or a hunch, implying a higher degree of uncertainty or a might/may nuance. -것 같아요 is stronger in its likelihood.
  1. 1✗ Wrong: 늦어서 저는 일찍 갔어요. (I was late, so I went early.)
✓ Correct: 늦을까 봐 일찍 갔어요. (I went early because I was worried I might be late.)
*Explanation:* The wrong sentence implies you were already late, which doesn't make sense with went early. -(으)ㄹ까 봐 correctly expresses the *reason* for an action (going early) as a *precaution against a feared outcome* (being late).

Quick FAQ

Q

How do I use -는지 with adjectives that end in a consonant vs. a vowel?

For adjectives ending in a consonant, use -은지 (e.g., 작다 -> 작은지). For adjectives ending in a vowel or ㄹ, use -ㄴ지 (e.g., 예쁘다 -> 예쁜지, 길다 -> 긴지). For verbs, it's always -는지 regardless of ending.

Q

What's the main difference between -(으)ㄹ지 and -(으)ㄹ지도 모르다?

-(으)ㄹ지 is used when you are unsure about a future action or decision (e.g., "I don't know whether to go

). -(으)ㄹ지도 모르다 expresses a possibility or a hunch (e.g.,
It might rain"). The former is about indecision, the latter about speculation.

Q

Can -(으)ㄹ까 봐 be used for positive worries?

No, -(으)ㄹ까 봐 specifically implies a negative or undesirable outcome that one is trying to avoid or prevent. It expresses a fear or concern.

Q

Is -는지 only for indirect questions?

While often used for indirect questions, -는지 can also express whether or not in a broader sense, indicating uncertainty about a fact or state, not necessarily a direct question being asked.

Cultural Context

These patterns are incredibly common in everyday Korean conversations, reflecting a cultural tendency towards indirectness and politeness. Instead of blunt statements, Koreans often use structures like -(으)ㄹ지도 모르다 to soften suggestions or express possibilities, avoiding definitive pronouncements that might seem too strong. -(으)ㄹ까 봐 is particularly useful for explaining actions driven by consideration for others or cautious planning, showcasing thoughtfulness.
Mastering these expressions will not only make your B1 Korean sound more natural but also help you navigate social interactions with greater cultural sensitivity. They allow for nuanced communication, which is highly valued in Korean society.

Conseils et astuces (4)

💡

L'astuce du 'ou pas'

Pour sonner plus naturel, combine l'affirmation et la négation, comme «좋은지 안 좋은지» (si c'est bien ou pas). «좋은지 안 좋은지 모르겠어요.»
frontend.learn_grammar.from_rule: Si oui ou non (-ㄴ/은/는지)
⚠️

Ne confonds pas avec la cause

Fais attention à ne pas confondre avec -(으)니까 qui exprime la raison. «비싼지» veut dire « si c'est cher », pas « parce que c'est cher ».
frontend.learn_grammar.from_rule: Questions indirectes : Savoir qui, où et si (-는지)
💡

Le raccourci 'Si oui ou non'

Pour dire 'si oui ou non', utilise la structure '-ㄹ지 말지'. C'est super naturel pour dire par exemple : «갈지 말지».
frontend.learn_grammar.from_rule: Incertitude future : Si... (-(으)ㄹ지)
💡

Le combo 'Au cas où'

Pour sonner super naturel, ajoute 혹시 (par hasard) au début de ta phrase. «혹시 모르니까 우산을 가져가요.»
frontend.learn_grammar.from_rule: Exprimer l'incertitude : Pourrait ou Peut-être (-(으)ㄹ지도 모르다)

Vocabulaire clé (5)

궁금하다 (gunggeumhada) to be curious 확실하다 (hwaksilhada) to be certain 결정하다 (gyeoljeonghada) to decide 비가 오다 (biga oda) to rain 늦다 (neutda) to be late

Erreurs courantes

When expressing uncertainty about a fact, use the polite form 모르겠어요 instead of the plain dictionary form.

Wrong: 그가 올지 모르다.
Correct: 그가 올지 모르겠어요.

-(으)ㄹ까 봐 is a clause. It needs an auxiliary verb like 걱정돼요 (I'm worried) or 서둘렀어요 (I hurried) to complete the thought.

Wrong: 비가 올까 봐요.
Correct: 비가 올까 봐 걱정돼요.

Maintain consistent politeness levels within your sentences.

Wrong: 누가 오는지 알아?
Correct: 누가 오는지 알아요?

Questions fréquentes (6)

Oui, il transforme une question en un bloc qui s'intègre dans une autre phrase. On l'utilise souvent avec 'savoir' ou 'demander'. «누구인지 알아요?»
-는지 est pour tous les verbes au présent (ex: «먹는지»). -은지 est pour les adjectifs avec consonne finale (ex: «좋은지»).
Absolument ! La politesse dépend du verbe final, pas de la particule -는지. Par exemple : «어디 가는지 아십니까?» (Savez-vous où il va ?).
À l'oral, tu peux finir par «...는지» pour laisser planer un doute, comme si tu te parlais à toi-même : «이거 맛있는지...» (Je me demande si c'est bon...).
Ça signifie 'si' ou 'si oui ou non' pour une action future ou incertaine. Ça connecte un doute à un verbe comme «모르다».
Oui ! Pour une condition (si il pleut, je reste), on utilise -(으)면. Ici, c'est pour un doute : «비가 올지 모르겠어요».
