실패하다

The Korean verb 실패하다 (silpaehada) is a cornerstone of the Korean vocabulary, representing the concept of failure or lack of success in a given endeavor. To understand this word, one must first look at its linguistic roots. It is a Hanja-derived word, composed of 실 (失 - lose) and 패 (敗 - defeat), combined with the active verb ending 하다 (to do). Literally, it translates to 'doing loss and defeat.' In everyday Korean life, this word is used across a vast spectrum of contexts, from minor personal setbacks to major professional catastrophes. Whether you are talking about a failed recipe, a failed business venture, or a failed attempt to catch a bus, 실패하다 is the standard term used to denote that the intended outcome was not reached.

Core Meaning

To fail or be unsuccessful in achieving a specific goal, task, or standard.

In Korean society, which is often characterized by high levels of competition and a strong emphasis on achievement, the word 실패하다 carries significant weight. It is not just a neutral description of an outcome; it often carries emotional undertones of disappointment or regret. However, it is also used in modern discourse to encourage resilience. You will frequently hear the proverb '실패는 성공의 어머니이다' (Failure is the mother of success) in educational and motivational settings. This demonstrates that while the word describes a negative state, its usage is deeply embedded in the narrative of growth and persistence. When using this word, it is crucial to pair it with the correct particle, usually -에, which indicates the area or target of the failure. For example, '시험에 실패하다' (to fail in an exam) is the standard construction.

Beyond formal achievement, 실패하다 can be applied to interpersonal dynamics and internal states. If a negotiation fails, it is '협상에 실패하다.' If someone fails to keep a promise, they might say '약속을 지키는 데 실패했다.' This versatility makes it one of the most useful verbs for learners to master at the A2 level. It transitions smoothly from simple concrete failures (like cooking) to more abstract concepts (like failing to control one's emotions). Understanding the nuances of 실패하다 also involves knowing its register. While it is a standard word used in both speech and writing, in very informal or slang contexts, younger people might use '망하다' (to be ruined) to express a more dramatic sense of failure.

Common Contexts

Academic exams, business ventures, cooking, sports matches, dieting, and personal relationships.

Finally, the word is often contrasted with its antonym, 성공하다 (to succeed). In many Korean textbooks, these two words are taught together to illustrate the binary nature of outcomes in tasks. However, in real-life Korean conversation, people often use hedging expressions with 실패하다 to soften the blow, such as '조금 실패한 것 같아요' (I think I failed a little bit) when referring to something minor like a haircut or a meal. This shows the social sensitivity surrounding the word and the importance of context when deploying it in conversation.

Using 실패하다 correctly involves understanding its grammatical requirements and the ways it changes based on the level of politeness and tense. As a 하다 verb, it follows the standard conjugation patterns. In the present tense, it becomes 실패해요 (polite) or 실패합니다 (formal). In the past tense, which is much more common since failure is often reported after the fact, it becomes 실패했어요 or 실패했습니다. One of the most important grammatical points for English speakers is the use of the particle -에. While we say 'failed the exam' in English, in Korean, we say '시험에 실패했다.' The '-에' functions as a location or target marker, indicating where the failure occurred.

Grammar Rule

[Noun] + 에 + 실패하다. This is the most common pattern for specifying what you failed at.

Another common pattern involves using the nominalizing form -는 데. This is used when you want to say you failed 'at doing' something. For example, '살을 빼는 데 실패했어요' (I failed at losing weight). Here, '살을 빼는 데' acts as a complex noun phrase meaning 'the act of losing weight.' This construction is slightly more advanced but very common in natural speech. It allows the speaker to be more specific about the action that didn't go as planned. Furthermore, 실패하다 can be used as an adjective-like modifier to describe a person or a thing: '실패한 감독' (a failed director) or '실패한 프로젝트' (a failed project). In these cases, the past participle form 실패한 is used.

In formal writing, such as news reports or academic papers, 실패하다 is often used in the passive-like construction 실패로 돌아가다 (to end in failure). For example, '회담이 실패로 돌아갔습니다' (The talks ended in failure). This adds a level of sophistication to your Korean. Additionally, you might see it combined with other verbs to show cause and effect, such as '실패해서 실망했어요' (I was disappointed because I failed). Mastering these patterns allows a learner to move beyond simple sentences and start expressing complex thoughts about challenges and setbacks. It is also worth noting that in negative sentences, you can use '실패하지 않다' (to not fail) or '안 실패하다' (though the former is much more common and preferred in most contexts).

Register and Politeness

Standard: 실패해요. Formal: 실패합니다. Written/Narrative: 실패한다. Honorific (rare): 실패하셨어요.

Lastly, when asking questions, 실패하다 is often used to seek advice or share experiences. '왜 실패했다고 생각하세요?' (Why do you think you failed?) is a common interview question or a deep conversation starter. For A2 learners, being able to conjugate this verb into the 'why' and 'because' structures is a key milestone. It allows for the description of past events and the analysis of results, which are fundamental communicative tasks in the intermediate stages of language acquisition.

If you spend any time watching Korean dramas (K-Dramas) or variety shows, you will encounter 실패하다 frequently. In K-Dramas, it is often used in high-stakes scenes—a character failing to protect a loved one, a business mogul failing to take over a company, or a student failing a crucial entrance exam. The word provides the dramatic tension needed for character growth and plot development. You might hear a character cry out, '제가 실패했어요!' (I failed!) in a moment of despair. This illustrates the word's capacity to convey deep emotional weight in a narrative setting.

Media Usage

News headlines often use '실패' (the noun form) to describe policy failures or economic downturns, while variety shows use '실패' for comedic effect during games.

In Korean variety shows like 'Running Man' or 'Infinite Challenge,' 실패 is a constant theme. When a cast member fails a silly challenge or a game, a large '실패' graphic often appears on the screen, accompanied by a sad or funny sound effect. Here, the word is used much more lightly and is part of the entertainment value. This contrast between the heavy usage in dramas and the lighthearted usage in variety shows is a great way for learners to see the word's full range. It also teaches that 'failure' in a Korean context can be a source of humor and relatability, not just tragedy.

In the Korean news, 실패하다 is used to discuss serious societal issues. For example, '출산율 정책이 실패했다' (The fertility rate policy has failed) is a common headline. In this context, the word is used to hold institutions accountable. It is also used in sports commentary when a player '실패하다' a goal attempt or a crucial play. By listening to these different sources, a learner can understand that while the core meaning remains 'to fail,' the implications vary significantly depending on whether the speaker is a news anchor, a comedian, or a fictional character. This exposure helps in developing a 'feel' for the word beyond its dictionary definition.

Conversational Frequency

High. It is one of the top 2000 most common words in spoken Korean.

Finally, you will hear this word in educational settings. Teachers might use it when discussing historical figures who failed initially but succeeded later, or when correcting a student's approach to a problem. In these settings, the word is often coupled with encouragement. Knowing how to hear and respond to 실패하다 in these various environments is a sign of a maturing Korean learner who can navigate the complexities of Korean social and professional life.

One of the most common mistakes English speakers make when using 실패하다 is confusing it with the word 틀리다 (teullida). In English, we might say 'I failed the question,' but in Korean, if you got an answer wrong on a test, you should use 틀리다. 실패하다 is reserved for the overall outcome of the exam (e.g., not passing the entire thing), whereas 틀리다 is for specific incorrect items. Using 실패하다 for a single math problem sounds very strange to a native speaker and makes it seem as though you had a major life crisis over one question.

Mistake 1: Failure vs. Incorrectness

Using '실패하다' when you mean 'to get something wrong' (use '틀리다' instead).

Another frequent error is the misuse of particles. As mentioned before, English speakers tend to use the object marker -을/를 because they are thinking of 'fail the test.' However, 실패하다 usually takes -에. While '시험을 실패하다' is occasionally heard and understood, '시험에 실패하다' is the grammatically standard and more natural way to express it. This is a classic 'interlanguage' error where the grammar of the first language (English) interferes with the production of the second language (Korean).

A third mistake is using 실패하다 when 못하다 (mothada) would be more appropriate. 못하다 means 'to be unable to do' or 'to do poorly.' If you simply didn't do a good job on something, but it wasn't a total failure, 못하다 is better. For instance, if you played a piano piece but hit a few wrong notes, you would say '피아노를 못 쳤어요' rather than '피아노를 실패했어요.' 실패하다 implies a definitive end-result that is negative, whereas 못하다 focuses on the lack of ability or poor performance during the process.

Mistake 2: Failure vs. Poor Performance

Using '실패하다' when you just performed poorly (use '못하다' instead).

Finally, learners sometimes over-honorify the word. Because failure is often a sensitive topic, learners might try to be extra polite and say '실패하셨어요' to someone. While grammatically possible, it can sound sarcastic or overly blunt depending on the relationship. In many cases, it's better to use softer language or indirect expressions like '잘 안 됐네요' (It didn't go well) when talking about someone else's failure to avoid sounding rude or insensitive.

While 실패하다 is the most general word for failure, Korean has several synonyms that are more specific to certain contexts. Understanding these will help you sound more like a native speaker. For example, if you are talking about failing a specific test or not being admitted to a school, 불합격하다 (bulhapgyeokhada) is the precise term. It literally means 'to not pass the standard.' This is the word you will see on official notices or websites when checking your exam results. Using 실패하다 in this context is okay, but 불합격하다 is much more professional and accurate.

Comparison: 실패하다 vs. 불합격하다

실패하다 is general (e.g., life, goals). 불합격하다 is specific to tests, applications, and certifications.

Another common alternative is 망하다 (manghada). This is a very strong word, often translated as 'to be ruined,' 'to go bust,' or 'to be screwed.' It is extremely common in casual speech among friends. If someone's business goes bankrupt, people might say '사업이 망했어요.' If a student feels they completely messed up an exam, they might say '시험 망했어!' while crying. It is much more informal and dramatic than 실패하다. However, you should avoid using 망하다 in formal writing or when speaking to superiors, as it can sound quite vulgar or overly emotional.

In literary or academic contexts, you might encounter 좌절되다 (jwajeoldoeda), which means 'to be thwarted' or 'to meet with a setback.' This is often used for plans or hopes that were crushed by external circumstances. For example, '그의 꿈이 좌절되었다' (His dream was thwarted). This carries a more tragic and passive tone than the active 실패하다. Another specialized word is 낙제하다 (nakjehada), which specifically means to 'fail a grade' or 'flunk a class' in school. While less common than it used to be, it is still used in educational settings to describe failing to meet the minimum requirements to move to the next level.

Other Related Terms

실수하다 (to make a mistake), 착오 (error), 패배하다 (to be defeated in a match).

By learning these variations, you gain the ability to express the 'flavor' of the failure. Is it a professional rejection (불합격)? A total disaster (망하다)? A thwarted dream (좌절)? Or a simple lack of success (실패)? Choosing the right word demonstrates a high level of linguistic sensitivity and helps you connect more deeply with native Korean speakers.
