Let Alone X: -은/는커녕

1. 1The First Clause (X-커녕): This part introduces the higher-level, more difficult, or expected item (X). This is the thing being dismissed as completely out of reach. It's the "let alone X" part of the phrase.

1. 1The Second Clause (Y-도 못...): This part presents the lower-level, more fundamental item (Y) that is also unattainable. This clause almost always contains a negative expression, typically using the particle ~도 (even) to emphasize the point. Common negative predicates include ~도 못하다 (can't even), ~도 없다 (don't even have), or ~도 아니다 (is not even).

• X (Ambitious): 휴가 (vacation). This is the bigger, more desirable period of rest.
• Y (Basic): 주말에 쉬는 것 (resting on the weekend). This is the smaller, more fundamental expectation of rest.
• Logic: Since the basic condition of resting on the weekend (Y) was not met, the more ambitious idea of a vacation (X) is presented as completely impossible. The particle -은/는커녕 is the bridge that links these two ideas into a single, powerful statement of frustration.

• X-은/는커녕 오히려 Y

• 칭찬은커녕 오히려 비난을 받았다. (Let alone praise, I received criticism instead.)

• X-은/는커녕 Y-도 못 [Verb]

• 해외여행은커녕 제주도도 못 가 봤어요. (Let alone a trip abroad, I haven't even been to Jeju Island.)

• X-은/는커녕 Y-도 없다

• 애인은커녕 친구도 없어요. (Let alone a partner, I don't even have friends.)

• X-은/는커녕 Y-만 [Verb/Noun]

• 용돈은커녕 심부름만 실컷 했어요. (Let alone getting an allowance, I only ran a ton of errands.)

• -은/는커녕 vs. -은/는 물론이고: This is the most direct contrast. 커녕 is for negative situations; 물론이고 is its positive counterpart. You cannot swap them.

• -은/는커녕 vs. -(으)ㄹ 뿐만 아니라: 커녕 creates a logical hierarchy of impossibility. -(으)ㄹ 뿐만 아니라 simply lists two related facts without the same sense of frustration or hierarchical contrast. Compare: 잠을 못 잤을 뿐만 아니라 밥도 굶었다 (I not only didn't sleep but also skipped a meal) vs. 잠은커녕 눕지도 못했다 (Let alone sleep, I couldn't even lie down).

• -은/는커녕 vs. -조차: 커녕 requires two elements for comparison (X and Y). -조차 focuses on a single, surprising negative element. It highlights that even the most basic or expected thing failed, often implying a sense of finality or betrayal. You use 커녕 to dismiss a big idea by pointing to a small failure; you use 조차 to emphasize your shock at that small failure itself.

Yes, absolutely. While its tone is strong, it's perfectly appropriate for formal contexts when you need to state a negative reality clearly. For example, in a report: 올해 흑자 달성은커녕 작년보다 손실이 더 커졌습니다. ("Let alone achieving a surplus this year, our losses have grown even larger than last year.") It is direct and leaves no room for misinterpretation.

They are very similar and often interchangeable. 돈은커녕 focuses on the noun 돈 (money), emphasizing the lack of the object itself. 벌기는커녕 focuses on the verb 벌다 (to earn), emphasizing the failure of the action. Choose 돈은커녕 if the existence of money is the main point. Choose 벌기는커녕 if the act of earning is the focus. For example: 돈은커녕 빚만 있다 (Let alone money, I only have debt) vs. 돈을 벌기는커녕 쓰고만 다닌다 (Let alone earning money, I only go around spending it).

No. -은/는커녕 is a connective particle that creates a logical dependency. It requires a second clause to resolve the contrast it sets up. A sentence like 밥은커녕. is incomplete and makes no sense. It's like saying "Let alone food." in English—the listener is left waiting for the rest of the thought.

In very casual, spoken conversation, you might hear it used as a standalone interjection to scornfully dismiss a suggestion. For example, if a friend with no money says, "I'm buying a sports car!" you might just scoff and say, 커녕! It's an abbreviated, highly informal way of saying, "Yeah right, let alone that..." This is very colloquial and should not be used in writing or formal situations.
