At this level, you can use 잘못되다 to talk about daily problems. If your phone stops working or you get the wrong answer on a test, you use this word. It helps you express that things are not going the way you wanted them to go.

Intermediate learners use 잘못되다 to describe complex situations. It is not just for small mistakes; it is for when projects or relationships have issues. You will often hear it in the past tense, 잘못됐다, to explain why something failed.

At the B2 level, you can use 잘못되다 to discuss nuance. It can imply a moral failure or a serious error in judgment. It is often used in professional contexts to describe why a business strategy or a social interaction went off the rails.

Word in 30 Seconds

  • Means 'to go wrong' or 'to be mistaken'.
  • Used for situations, plans, and outcomes.
  • Conjugates like a verb but acts as an adjective.
  • Essential for everyday Korean conversation.

Hey there! 잘못되다 is one of those essential Korean words you will encounter almost every day. At its core, it means to go wrong or to be mistaken. Think of it as the opposite of things going smoothly.

You can use this word for almost anything: a math problem you solved incorrectly, a plan that failed, or even a situation that took an unlucky turn. It is a versatile adjective that helps you express frustration or identify errors in a natural way.

When you say something is 잘못되다, you are essentially pointing out that the current state of affairs is not what was expected or desired. It is a very helpful word for troubleshooting and explaining why things aren't working out!

The word 잘못되다 is a compound formed from two distinct parts: 잘못 (meaning 'fault' or 'error') and 되다 (meaning 'to become'). Historically, it evolved to describe the state of having 'become a fault.'

In older Korean, the concept of 'wrongness' was often tied to moral or procedural failures. Over time, the language simplified these concepts into this single, powerful phrase. It reflects a deep linguistic history where the Korean people categorized events based on whether they aligned with the 'right' path or the 'wrong' path.

Interestingly, while it functions as an adjective, it carries a strong sense of action because of the -되다 suffix. It shows how Korean uses verb-like endings to describe states of being, a common trait in agglutinative languages. It has remained a staple in the language for centuries, proving its enduring utility.

You will hear 잘못되다 in many different scenarios. It is very common in casual conversation when something breaks or goes haywire. For example, if your computer crashes, you might say it '잘못됐다'.

In formal settings, it is used to describe systemic failures or errors in judgment. It is slightly more serious than just saying 'no' or 'bad.' It implies that there was an original plan that has now been compromised.

Common collocations include 일이 잘못되다 (the work went wrong) or 생각이 잘못되다 (the thinking is mistaken). The register is quite flexible, making it suitable for both a quick chat with a friend and a professional report about a project's status.

1. 잘못되다가는: Used to mean 'if things go wrong' or 'in the worst case scenario.' Example: '잘못되다가는 큰일이 날 수도 있어.' (If things go wrong, it could be a big problem.)

2. 잘못된 만남: Literally 'a wrong meeting,' often used to describe a relationship or encounter that shouldn't have happened. Example: '그들의 만남은 잘못된 만남이었다.' (Their meeting was a mistake.)

3. 잘못된 길로 가다: To go down the wrong path (often used for life choices). Example: '그는 잘못된 길로 가고 있다.' (He is going down the wrong path.)

4. 왠지 잘못된 것 같다: 'Somehow, it feels wrong.' Used when you have a gut feeling about a situation. Example: '왠지 잘못된 것 같아.' (It feels like something is wrong.)

5. 잘못되게 하다: To cause something to go wrong. Example: '일을 잘못되게 하지 마.' (Don't let the work go wrong.)

Grammatically, 잘못되다 acts as an adjective, but because it ends in -되다, it conjugates like a verb. You will often see it in the past tense form 잘못됐다 (it went wrong).

The pronunciation is tricky because of the batchim (final consonant) rules. It is pronounced as [잘몯뙤다] or [잘몯뒈다]. The 'ㄷ' sound at the end of '잘못' interacts with the 'ㄷ' in '되다' to create a tense 'ㄸ' sound.

It doesn't have plural forms because it is an adjective describing a state. When using it, remember that it is often paired with the subject particle '이/가' (e.g., 일이 잘못됐다). It is a perfect example of how Korean grammar relies on particles to link states to subjects.

Fun Fact

The word is a perfect example of how Korean combines a noun and a suffix to create a new state-describing word.
