तुम क्या सीखोगे

In this chapter, you're about to take a big leap and speak like a true Korean native! You'll move beyond just saying "I'm sure or I think"; you'll learn to precisely and subtly convey your level of certainty and logic in your speech. Imagine your friend hasn't arrived yet, and you see heavy traffic; by learning «-ㄹ/을 법하다,» you can say, "They're likely stuck in traffic." Or, when you're 100% sure something is impossible, with «-ㄹ 리가 없다,» you can decisively say, "There's no way!" In this lesson, you'll learn powerful tools like «-ㄹ/을 게 분명하다» to express yourself without a shred of doubt when you're absolutely certain about something. Wow, how great it is not to worry anymore! You can even use «-았/었을 것이다» to logically deduce about past events you didn't personally witness, like

They must have gone out yesterday.
These structures fit together like a puzzle, allowing you to express anything from a likely guess to absolute certainty in the best possible way. After this chapter, you'll be able to confidently express your opinions with reasoning and certainty in any conversation. You'll even learn how to use «-기는 하다» to concede a point politely before adding a small but and qualifying your statement. Ready for a much deeper and more authentic Korean conversation? Let's get started!

अध्याय गाइड

Overview

Welcome, B2 Korean learners! Are you ready to elevate your Korean grammar to a truly native-like level? This chapter is your gateway to expressing certainty and logic with precision and nuance.
Moving beyond simple I think or "I'm sure," you'll master expressions that allow you to convey exactly how confident you are about a statement, or how logically you've deduced something. This is a crucial step in achieving fluency and engaging in deeper, more authentic conversations.
At the B2 CEFR level, the expectation is to communicate effectively in a wide range of situations, and that includes expressing your thoughts with conviction and sound reasoning. By learning structures like -ㄹ/을 법하다 for likelihood, -ㄹ 리가 없다 for impossibility, -ㄹ/을 게 분명하다 for absolute certainty, and -았/었을 것이다 for logical past deductions, you'll gain the tools to articulate your opinions with confidence. You'll even learn -기는 하다 to gracefully concede a point before introducing a counter-argument.
These advanced Korean grammar patterns will make your speech more sophisticated and natural, helping you sound less like a textbook and more like a native speaker.

How This Grammar Works

Let's dive into the powerful tools for expressing certainty and logic in Korean. First, for expressing that something is logically likely or probable, we use -ㄹ/을 법하다. This structure suggests that based on circumstances, something seems like it could reasonably happen.
For instance, «그는 바빠서 못 올 법해요» (He's busy, so he's likely unable to come). When you're absolutely certain that there's no way something could be true, you'll use -ㄹ 리가 없다. It conveys strong disbelief or a logical impossibility.
For example, «그가 거짓말을 했을 리가 없어요» (There's no way he lied).
To express absolute certainty, when you have no doubt whatsoever, the phrase -ㄹ/을 게 분명하다 is your go-to. It means "it's clear that or it must be. Imagine saying, 내일 비가 올 게 분명해요" (It's definitely going to rain tomorrow). For making a logical past guess, like deducing what must have happened, we use -았/었을 것이다.
This is perfect for speculating about past events you didn't witness but can logically infer. For example, «그는 어제 집에 일찍 갔을 거예요» (He must have gone home early yesterday). Finally, to acknowledge with a 'but', or to concede a point before offering a qualification, we use -기는 하다.
This softens your statement and adds nuance. For instance, «맛있기는 한데, 너무 비싸요» (It is delicious, but it's too expensive). Mastering these B2 Korean grammar structures will significantly enhance your expressive capabilities.

Common Mistakes

  1. 1Wrong: «비 올 것 같아.» (Sounds too casual/simple for strong certainty)
Correct: «비가 올 게 분명해요.» (It's definitely going to rain.)
*Explanation:* While «것 같다» expresses probability, -ㄹ/을 게 분명하다 conveys a much stronger, almost undeniable certainty, which is what the speaker truly intends here.
  1. 1Wrong: «그가 어제 집에 일찍 가야 했어.» (This implies 'had to go,' not 'must have gone' as a deduction)
Correct: «그는 어제 집에 일찍 갔을 거예요.» (He must have gone home early yesterday.)
*Explanation:* -았/었을 것이다 is specifically for logical deduction about past events. «가야 했어» means he *had* to go, indicating obligation, not inference.
  1. 1Wrong: «이 음식은 맛있어. 하지만 비싸.» (A bit blunt, lacks nuance)
Correct: «이 음식은 맛있기는 한데, 너무 비싸요.» (This food is delicious, but it's too expensive.)
*Explanation:* -기는 하다 acknowledges the positive aspect (delicious) first, then gently introduces the negative (expensive), making the statement more polite and nuanced than a direct but.

Quick FAQ

Q

What's the main difference between -ㄹ/을 법하다 and just using 아마 (probably)?

While 아마 expresses general probability, -ㄹ/을 법하다 specifically implies that something is *logically reasonable* or *plausible* given the circumstances, often based on common sense or observable facts. It adds a layer of reasoned deduction.

Q

Can -았/었을 것이다 be used for future deductions?

No, -았/었을 것이다 is exclusively for logical deductions about *past* events. For future deductions, you would typically use -ㄹ/을 것이다 (e.g., «내일 비가 올 것이다» - It will probably rain tomorrow).

Q

Is -ㄹ 리가 없다 considered informal?

No, -ㄹ 리가 없다 is a versatile expression usable in both formal and informal contexts. Its formality depends more on the politeness level of the ending (e.g., -ㄹ 리가 없어요 vs. -ㄹ 리가 없어).

Q

When is -기는 하다 more appropriate than a simple yes, but...?

-기는 하다 is perfect when you want to acknowledge a point or agree with something, but immediately want to add a caveat, a criticism, or a different perspective. It softens the but and shows you've considered the other side.

Cultural Context

These expressions of certainty and logic are deeply embedded in how native Korean speakers communicate, reflecting a culture that values thoughtful consideration and polite nuance. Using structures like -ㄹ/을 법하다 allows for logical reasoning without sounding overly assertive, while -기는 하다 enables polite disagreement or qualification, crucial in a high-context society. You'll hear these B2 Korean grammar patterns frequently in everyday conversations, news analysis, and even debates, as they allow speakers to express strong opinions with appropriate levels of confidence and deference.
Mastering them will not only improve your grammar but also your cultural understanding.

टिप्स और ट्रिक्स (4)

💡

The 'Duh' Factor

इसे तब इस्तेमाल करो जब नतीजा सबको साफ़ दिख रहा हो। जैसे 'उसने रात भर पढ़ाई की है, तो पास होना तो बनता है': «시험에 합격할 법해요.»
frontend.learn_grammar.from_rule: तार्किक अनुमान: -ㄹ/을 법하다
💬

ड्रामा क्वीन मोड

यह फ्रेज़ K-dramas में बहुत पॉपुलर है। जब कोई बड़ा ट्विस्ट आता है, तो अक्सर लोग चिल्लाकर कहते हैं: «말도 안 돼! 그럴 리가 없어!» (बकवास! ऐसा हो ही नहीं सकता!)
frontend.learn_grammar.from_rule: ऐसा हो ही नहीं सकता... (-ㄹ 리가 없다)
🎯

'게' का जादू

याद रखो, '게' असल में '것이' का छोटा रूप है। बातचीत में '게' का इस्तेमाल तुम्हें ज़्यादा स्वाभाविक और धाराप्रवाह बनाता है। «이건 진짜일 게 분명해.»
frontend.learn_grammar.from_rule: पूर्ण निश्चितता व्यक्त करना (-ㄹ/을 게 분명하다)
🎯

सबूत का नियम

इस ग्रामर का इस्तेमाल तब करो जब तुम्हारे पास कोई 'सुराग' हो। अगर ज़मीन गीली है, तो बोलो «비가 왔을 거예요»। अगर बिना किसी वजह के बस तुक्का मार रहे हो, तो «-았/었을지도 몰라요» ज़्यादा सही रहेगा।
frontend.learn_grammar.from_rule: तार्किक भूतकाल अनुमान: 'किया होगा' (-았/었을 것이다)

The Late Friend

Review Summary

  • V/A + -ㄹ/을 법하다
  • V/A + -ㄹ/을 리가 없다
  • V/A + -았/었을 것이다

सामान्य गलतियाँ

The pattern is almost exclusively used with '없다' to show impossibility. Using '있다' makes it a rhetorical question which is much rarer.

Wrong: 그가 올 리가 있어요? (Is there a way he's coming?)
सही: 그가 올 리가 없어요. (There's no way he's coming.)

In spoken Korean, -ㄹ 것이에요 is almost always contracted to -ㄹ 거예요. Using the uncontracted form sounds overly stiff.

Wrong: 어제 갔을 것이에요.
सही: 어제 갔을 거예요.

-기는 하다 feels incomplete without a contrasting clause (하지만/한데). It is used to concede a point before adding a 'but'.

Wrong: 그는 똑똑하기는 해요. (He is smart.)
सही: 그는 똑똑하기는 하지만 공부는 안 해요. (He is smart, but he doesn't study.)

सामान्य प्रश्न (6)

हाँ, इसके लिए -었/았을 법하다 का इस्तेमाल करो। इसका मतलब है 'लॉजिक के हिसाब से ऐसा हुआ होगा'। जैसे: «그가 벌써 갔을 법해요.»
그럴 법하다 लॉजिक पर आधारित है, जबकि 그럴 듯하다 का मतलब है कि कोई बात सुनने में सही लग रही है, चाहे वो सच हो या न हो। जैसे: «그럴 듯한 핑계네요.»
'리' शब्द Hanja 理 (तर्क/लॉजिक) से आया है। तुम इसे '이해' (समझना) जैसे शब्दों में भी देखोगे। तो असल में तुम कह रहे हो कि 'कोई लॉजिक ही नहीं है' जैसे: «그럴 리가 없어»।
बिल्कुल! अगर कोई तुम पर ऐसा इल्ज़ाम लगाए जो तुमने किया ही नहीं, तो कहो: «내가 그럴 리가 없어» (हो ही नहीं सकता कि मैंने ऐसा किया हो)।
-ㄹ 것이다 एक सामान्य भविष्य या एक सरल अनुमान है। -ㄹ 게 분명하다 साक्ष्य के आधार पर 'निश्चितता' की एक भारी परत जोड़ता है। यह 'मैं जाऊँगा' और 'मुझे यकीन है कि मैं जाऊँगा' (एक पर्यवेक्षक के दृष्टिकोण से) के बीच का अंतर है।
हाँ! -았/었을 게 분명하다 का प्रयोग करें। उदाहरण: '그는 이미 밥을 먹었을 게 분명해요' (मुझे यकीन है कि उसने पहले ही खा लिया है)।
