What You'll Learn

Hey friend! Ready to level up your Korean in a serious way? This chapter is super exciting because it teaches you how to elegantly and formally explain the reasons behind actions and connect them to their results. I know, you might be thinking, 'Wow, that sounds advanced!' but don't worry, it's not difficult at all. Together, we'll learn how to use phrases like '-로 인하여' or '-로 말미암아' to say 'due to X, Y happened,' especially when the event is significant and serious. For instance, if you want to say, 'Due to the heavy rain, our trip was cancelled,' you won't just use a simple phrase anymore! Next, you'll discover how to state a consequence once something has been established. With '-는 이상,' you can say, 'Now that we've decided, we must do it.' Imagine how useful these will be when you want to understand why something happened in Korean news or when you need to give a firm, official explanation yourself. You'll even learn how to explain something based on a law or an official document, using '-에 의거하여.' By the end of this chapter, you'll be able to explain the reasons and logic behind events like a professional Korean speaker, make strong conclusions, and express your thoughts with great confidence and authority. Let's make your Korean amazing!

How This Grammar Works

This chapter introduces several powerful Korean grammar patterns that enable you to express causation, logical conclusions, and formal justifications. Let's break them down:
-로 인하여 (Formal Causation: Due to) and -로 말미암아 (The Formal Cause: Due to) are used to express the cause or reason for a significant or serious event, often with a somewhat negative or impactful consequence. They are highly formal and frequently appear in written reports, news, or formal speeches.
* 폭설로 인하여 비행기 운항이 전면 취소되었다. (Due to heavy snowfall, all flights were cancelled.)
* 부주의로 말미암아 큰 사고가 발생했습니다. (Due to carelessness, a major accident occurred.)
-는 바람에 (Academic Causation: Due To) indicates a cause that led to an unexpected or often negative outcome. While sometimes used in everyday speech, it carries a sense of consequence, making it suitable for explaining unfortunate events.
* 갑자기 비가 오는 바람에 소풍이 취소되었어요. (Due to the sudden rain, the picnic was cancelled.)
-ㄴ/은/는 이상 (Since / Now That) is used to state that once a certain condition or situation is established, a specific action or consequence logically follows. It implies a firm resolve or an unavoidable conclusion.
* 시작한 이상, 끝까지 해야 합니다. (Now that we've started, we must finish it.)
-ㄴ/은/는 즉 (Formal 'Namely' Logic) indicates a logical conclusion or consequence based on a preceding statement or condition. It can mean "if... then..." or "as soon as..." in a formal context, establishing a direct logical link.
* 규정을 위반한 즉, 벌금을 내야 합니다. (If you violate the regulations, you must pay a fine.)
-에 의거하여 (Formal Basis: Based On, In Accordance With) is used to state that an action or decision is based on a specific law, rule, document, or established fact. It adds an official and authoritative tone.
* 관련 법규에 의거하여 처벌이 결정될 것입니다. (Punishment will be determined in accordance with relevant laws.)

Common Mistakes

  1. 1✗ Wrong: 심심하는 바람에 영화를 봤어요.
✓ Correct: 심심해서 영화를 봤어요. (I watched a movie because I was bored.)
*Explanation:* -는 바람에 typically implies an unexpected or often negative outcome, not a simple, positive, or neutral reason like being bored. For everyday reasons, simpler structures like -아/어서 are more appropriate.
  1. 1✗ Wrong: 그의 실수로 말미암아 프로젝트가 성공했다.
✓ Correct: 그의 실수로 인하여 프로젝트에 차질이 생겼다. (Due to his mistake, the project encountered a setback.)
*Explanation:* Both -로 인하여 and -로 말미암아 are used for significant causes, often leading to serious or negative consequences. Using them for a positive outcome like project success is unnatural. They convey a sense of gravity, which usually aligns with negative impacts.
  1. 1✗ Wrong: 약속했는 이상, 변경할 수 없다.
✓ Correct: 약속한 이상, 변경할 수 없다. (Now that I've promised, I cannot change it.)
*Explanation:* For verbs, -는 이상 is attached to the verb stem as -는 이상 (present tense) or -ㄴ/은 이상 (past tense). For adjectives, it's -ㄴ/은 이상. In this case, "약속하다" is a verb, so "약속한 이상" (past tense) or "약속하는 이상" (present tense) is correct.

Quick FAQ

Q

When should I use -로 인하여 vs. -아/어서 for causation in Korean?

-로 인하여 is much more formal and used for significant, often serious, causes with impactful consequences, typically in written or official contexts. -아/어서 is a general, everyday causal connector suitable for all situations, formal or informal.

Q

Is -는 바람에 always negative in its implication?

While -는 바람에 most frequently implies an unexpected or negative outcome, it can occasionally be used for neutral or even slightly positive, unexpected results, but the emphasis is always on the 'unexpected' aspect leading to a consequence. It is not generally used for planned or desired outcomes.

Q

Can -ㄴ/은/는 이상 be used in casual speech?

While it's more common in formal or semi-formal settings, -ㄴ/은/는 이상 can be used in casual speech among close friends to express a firm resolution or logical consequence, but it still maintains a slightly more serious tone than simpler expressions.

Q

What's the main difference between -로 인하여 and -로 말미암아?

Both are very similar and often interchangeable in meaning and formality, indicating a cause for a significant event. Some linguists suggest -로 말미암아 might imply a slightly more direct or ultimate cause, while -로 인하여 can refer to a more immediate or contributing factor, but this distinction is subtle and not always strictly observed.

Cultural Context

These formal Korean grammar patterns are indispensable for understanding and participating in higher-level discourse in Korea. You'll encounter -로 인하여, -로 말미암아, and -에 의거하여 frequently in news broadcasts, official documents, legal texts, academic papers, and formal speeches. Using them demonstrates a high level of linguistic sophistication and respect for the gravity of the topic. -ㄴ/은/는 이상 adds a sense of logical deduction and resolve, often heard in discussions about commitments or principles. Mastering these allows you to engage with complex topics like a professional, reflecting a sophisticated understanding of B2 Korean communication.
