解析 비효율적이다 in your Level:
At the A1 level, you can think of 비효율적이다 as a way to say something is 'not good' because it takes too much time or energy. Even though it looks like a long word, it is very useful for basic descriptions. At this stage, you should focus on the simple sentence structure: '[Subject]은/는 비효율적이에요.' For example, if you are studying Korean by just looking at words without writing them, and it takes a long time to remember, you can say '이 방법은 비효율적이에요' (This method is inefficient). You don't need to worry about complex grammar yet. Just remember that it is the opposite of '효율적이다' (efficient). Think of it as a tool to complain politely about a process that is too slow or wasteful. It's a great word to use when you want to sound a bit more serious than just saying '나빠요' (it's bad). You might use it when talking about a long line at a store or a confusing homework assignment. The key is to recognize the '비-' at the beginning, which usually means 'not' in Korean words derived from Chinese characters. This is your first step into 'Hanja' (Chinese character) based vocabulary, which makes up a large part of the Korean language. By learning this word, you are beginning to build the foundation for more advanced academic and professional Korean. Just practice the basic conjugation '비효율적이에요' and you will be able to express a lot of logical frustration in a simple way.
At the A2 level, you can start using 비효율적이다 to connect ideas using basic conjunctions like '-아/어서' (because) and '-지만' (but). You should also learn how to use the adjective form '비효율적인' to describe nouns. For example, '비효율적인 방법' (an inefficient method). At this stage, you can use the word to talk about your daily routines, study habits, or travel plans. If you go to the supermarket three times a day instead of once, you can say, '마트에 세 번 가는 것은 비효율적이에요' (Going to the mart three times is inefficient). You are moving beyond simple descriptions to explaining *why* something is a problem. You might also start noticing this word in simple news clips or blog posts about productivity. It is a very common word in the 'Pali-pali' (hurry-hurry) culture of Korea, so using it correctly will help you fit in with the local mindset of valuing time. Practice saying '비효율적이라서 싫어요' (I don't like it because it's inefficient). This level is all about expanding the contexts where you use the word, moving from simple objects to simple actions and habits. You should also be careful with the spelling, as the '효' and '율' sounds can be tricky for beginners. Repeat the word slowly: bi-hyo-yul-jeok-i-da.

At the B1 level, you should be able to use 비효율적이다 in professional and academic settings. This is where the word really shines. You can use it to critique work processes, discuss economic issues, or talk about environmental problems. For example, '에너지를 낭비하는 것은 매우 비효율적입니다' (Wasting energy is very inefficient). You should also be comfortable with various politeness levels, from the formal '비효율적입니다' used in presentations to the neutral '비효율적이다' used in writing. At this stage, you should also start comparing it with similar words like '비능률적이다' (ineffective/inefficient) and '비생산적이다' (unproductive). You can use more complex grammar patterns like '-기 때문에' (because) or '-(으)ㄴ 것 같다' (it seems like). For instance, '이 시스템은 너무 오래되어서 비효율적인 것 같아요' (I think this system is inefficient because it's too old). You are now using the word to express opinions and provide logical arguments. You will hear this word in office meetings, university lectures, and more detailed news reports. It becomes a tool for problem-solving. When you identify something as '비효율적,' the next step is usually to suggest a '효율적' (efficient) alternative. This shows that you are thinking critically in Korean.

At the B2 level, you can use 비효율적이다 to discuss abstract concepts and complex systems. You should be able to use it in written essays (using the '-다' plain form) and formal debates. You can talk about '비효율적인 자원 배분' (inefficient resource allocation) or '비효율적인 관료주의' (inefficient bureaucracy). Your vocabulary should expand to include related nouns like '비효율성' (inefficiency). For example, '이 계획의 가장 큰 문제는 비효율성입니다' (The biggest problem with this plan is the inefficiency). You should also be able to use the word with advanced grammar structures like '-음에도 불구하고' (despite) or '-ㄹ 정도로' (to the extent that). For instance, '비효율적임에도 불구하고 여전히 사용되고 있습니다' (Despite being inefficient, it is still being used). At this level, you understand the nuance between inefficiency in terms of time, cost, and effort. You can also use the word to describe psychological states, such as '비효율적인 감정 소모' (inefficient emotional drain/waste). You are expected to use this word with precision, distinguishing it clearly from '비효과적' (ineffective) in technical discussions. Your ability to use such Sino-Korean terms accurately is a hallmark of your transition into upper-intermediate proficiency.

At the C1 level, 비효율적이다 is used with high-level sophistication. you can analyze the systemic roots of inefficiency in society, economics, or philosophy. You might use it in a thesis or a high-level business report to describe '구조적 비효율성' (structural inefficiency). You can engage in deep discussions about the trade-offs between efficiency and other values like equity or stability. For example, '때로는 민주주의 절차가 비효율적으로 보일 수 있지만, 그것은 공정성을 위한 필수적인 과정입니다' (Sometimes democratic procedures may seem inefficient, but they are essential processes for fairness). You should be able to use the word in idiomatic or highly formal contexts, and understand its use in classical-style Korean writing. You can also use it to critique subtle aspects of language or communication, such as '비효율적인 수사법' (inefficient rhetoric). Your command of the word allows you to use it not just as a critique, but as a starting point for complex theoretical analysis. You understand how the concept of 'efficiency' has evolved in the Korean cultural context and can comment on it using this vocabulary. You can also handle complex passive or causative forms related to the concept, though the word itself remains an adjective.

At the C2 level, your use of 비효율적이다 is indistinguishable from that of an educated native speaker. You can use it to navigate the most formal and high-stakes environments, such as diplomatic negotiations, legal arguments, or top-tier academic journals. You understand the historical and philosophical baggage the word carries in the context of South Korea's rapid modernization. You can use it to discuss '파레토 비효율성' (Pareto inefficiency) in economics or '열역학적 비효율' (thermodynamic inefficiency) in physics with ease. You can also use it sarcastically or poetically if the context allows. For instance, you might describe a beautiful but convoluted piece of literature as '비효율적이지만 매혹적인 문체' (an inefficient but fascinating writing style). You are fully aware of the social implications of labeling something as '비효율적' and can use the word strategically to influence opinions or drive policy. Your mastery extends to all derived forms, related Hanja expressions, and the most obscure synonyms. You can explain the difference between '비효율' and '저효율' to other learners. At this level, the word is not just a vocabulary item; it is a concept that you can manipulate with total linguistic and cultural fluency.

비효율적이다 30秒了解

  • Means 'inefficient' or 'wasteful' regarding resources.
  • Used in both formal (business) and informal (daily life) contexts.
  • Commonly paired with '시간' (time) or '돈' (money).
  • Essential word for critiquing methods and seeking optimization.
The Korean word 비효율적이다 is a descriptive verb (adjective) that translates to 'to be inefficient.' To understand its profound weight in the Korean language, one must first look at the cultural backdrop of South Korea, a nation famous for its rapid economic development known as the 'Miracle on the Han River.' In this high-speed society, efficiency is not just a preference; it is a core value. The word is constructed from three Hanja components: 비 (非) meaning 'not' or 'non-', 효율 (效率) meaning 'efficiency,' and the suffix 적 (的) which transforms the noun into an attributive form, followed by the copula 이다 meaning 'to be.' When you describe something as 비효율적이다, you are pointing out that the input—whether it be time, money, effort, or resources—is not yielding the maximum possible output.
Core Concept
At its heart, this word describes a mismatch between effort and result. It is used when a process is clunky, a method is outdated, or a person's way of working involves unnecessary steps.

이 방식은 시간 낭비가 심해서 아주 비효율적이다. (This method is very inefficient because it wastes a lot of time.)

In a professional setting, calling a colleague's plan 비효율적이다 is a serious critique, suggesting that they are wasting company resources. However, it is also used in daily life, such as when discussing study habits or travel routes. If you take a bus that stops at every single station instead of the express train, a Korean friend might say, '그건 너무 비효율적이야' (That's too inefficient).
Etymological Nuance
The Hanja '효' (效) refers to effect or result, and '율' (率) refers to a rate or ratio. Thus, '효율' is the 'rate of result.' Adding '비' (非) negates this entire ratio, suggesting the ratio of work to result is broken.

종이 서류를 사용하는 것은 현대 사회에서 비효율적이다. (Using paper documents is inefficient in modern society.)

이 엔진은 연료 소비가 많아 매우 비효율적이다. (This engine is very inefficient due to high fuel consumption.)

회의를 세 시간이나 하는 것은 비효율적이다. (Having a meeting for three hours is inefficient.)

그의 학습 방법은 다소 비효율적이다. (His study method is somewhat inefficient.)

Register and Tone
While it sounds technical, it is used across all levels of formality. In a research paper, it describes systemic failure; in a kitchen, it describes a messy cook. It is a versatile tool for critique.
Understanding 비효율적이다 allows you to navigate the nuances of Korean productivity expectations. It is not just about being slow; it is about being 'unnecessarily' slow or wasteful. When someone says '비효율적이다,' they are usually implying that there is a better, smarter way to achieve the same goal. This word is essential for anyone working in a Korean office or studying in a Korean university, as the optimization of systems is a constant topic of conversation. It reflects a mindset that seeks to maximize utility and minimize waste in every aspect of life, from urban planning to personal time management.
Using 비효율적이다 correctly requires an understanding of how '-적' (suffix) and '이다' (to be) work together. In Korean, '-적' creates a noun that acts like an adjective, but it still requires the copula '이다' to function as a predicate in a sentence. For example, to say 'It is inefficient,' you say '비효율적이다.' To modify a noun directly, you change it to '비효율적인,' such as '비효율적인 방법' (an inefficient method). This distinction is crucial for learners.
Grammatical Structure
Noun + -적 + 이다. This pattern is extremely common for Sino-Korean words. You conjugate the '이다' part to change the politeness level or tense.

그 시스템은 상당히 비효율적이었습니다. (That system was quite inefficient.)

When you want to use it in the middle of a sentence to connect ideas, you might use '비효율적이라서' (because it is inefficient) or '비효율적이지만' (it is inefficient, but...). For instance, '이 방법은 비효율적이라서 바꾸기로 했습니다' (We decided to change this method because it is inefficient). Notice how the '이다' changes to '이라서.'
Common Conjugations
Informal Polite: 비효율적이에요. Formal Polite: 비효율적입니다. Past Tense: 비효율적이었어요. Future/Suppositional: 비효율적일 거예요.

너무 비효율적인 일에 시간을 쓰지 마세요. (Don't spend time on such inefficient work.)

이것은 경제적으로 매우 비효율적입니다. (This is economically very inefficient.)

이론적으로는 가능하지만 실제로는 비효율적일 수 있습니다. (It is theoretically possible but can be inefficient in practice.)

우리는 비효율적이라고 생각되는 모든 절차를 삭제했습니다. (We deleted all procedures considered inefficient.)

Sentence Patterns
[Subject] + [Adverb] + 비효율적이다. Example: '정부의 정책은 가끔 비효율적이다' (Government policies are sometimes inefficient). Adverbs like '매우' (very), '상당히' (considerably), and '극도로' (extremely) often accompany this word.
By mastering these patterns, you can express critique in a sophisticated way. Instead of just saying something is 'bad' (나쁘다), saying it is '비효율적이다' provides a specific reason—the waste of resources. This makes your Korean sound more precise and professional. Whether you are describing a software bug, a bad study habit, or a convoluted bureaucracy, this word will serve as a powerful tool in your linguistic arsenal.
You will encounter 비효율적이다 in a variety of real-world scenarios in Korea. Most commonly, it is found in professional and academic environments. In a corporate office in Seoul, you might hear a manager during a strategy meeting saying, '현재의 업무 프로세스는 너무 비효율적입니다. 개선이 필요해요' (The current work process is too inefficient. We need improvement). This word is a staple of business critiques because it sounds objective rather than personal.
News and Media
News anchors frequently use this word when reporting on government spending, public transportation issues, or economic trends. For example, '예산 집행이 비효율적이라는 지적이 나오고 있습니다' (Points are being raised that budget execution is inefficient).

TV 토론: '이 정책은 세금 낭비이며 매우 비효율적입니다.' (TV Debate: 'This policy is a waste of taxes and very inefficient.')

In the world of technology and software, developers use it to describe code that consumes too much memory or processing power. If an app takes too long to load, a user might leave a review saying, '앱이 너무 무겁고 비효율적이에요' (The app is too heavy and inefficient).
Education and Self-Help
You'll see this word constantly in Korean 'Gong-bu' (study) YouTube channels or blogs. Influencers will teach 'How to avoid inefficient study habits' (비효율적인 공부 습관을 피하는 법). In a competitive education system, efficiency in learning is a hot topic.

선생님: '단순 암기는 때때로 비효율적일 수 있습니다.' (Teacher: 'Simple memorization can sometimes be inefficient.')

블로그 제목: '나의 비효율적인 아침 루틴 고치기' (Blog Title: Fixing my inefficient morning routine.)

광고: '더 이상 비효율적인 다이어트는 그만하세요!' (Ad: Stop inefficient dieting now!)

뉴스: '서울의 교통 체증은 경제적으로 매우 비효율적입니다.' (News: Traffic congestion in Seoul is economically very inefficient.)

Daily Conversations
While less common in casual small talk than '힘들다' (it's hard), it is used when friends discuss life choices. '그렇게 멀리 돌아가는 건 비효율적이야' (Going that far around is inefficient). It adds a layer of logic to the advice.
In summary, '비효율적이다' is a word of critique and optimization. It is heard wherever systems are being analyzed, whether those systems are national economies, corporate workflows, or personal habits. Hearing it usually signals a desire for change and improvement.
One of the most frequent mistakes English speakers make when using 비효율적이다 is confusing it with other words related to 'bad' or 'difficult.' For example, a learner might say '비효율적이다' when they actually mean '불편하다' (inconvenient). While an inefficient system might be inconvenient, the words are not interchangeable. '비효율적이다' specifically targets the waste of resources relative to the outcome.
Mistake 1: Using it for 'Slow'
If a person is just slow at walking, don't say they are '비효율적이다.' Use '느리다' (slow). Only use '비효율적이다' if their path choice or method makes the slowness unnecessary.

Wrong: 인터넷이 비효율적이에요. (The internet is inefficient - when you mean it's slow.)
Right: 인터넷이 느려요. (The internet is slow.)

Another common error is grammatical. Because it ends in '-적,' many learners forget to add '이다' to make it a verb. Saying just '이거 비효율적' is grammatically incomplete in formal settings, though it might pass in very casual texting.
Mistake 2: Confusing with '비효과적이다'
'비효과적이다' means 'ineffective' (doesn't work). '비효율적이다' means 'inefficient' (works, but wastes resources). A medicine that doesn't cure a cold is '비효과적,' but a medicine that cures it but costs $10,000 is '비효율적.'

Wrong: 이 약은 비효율적이에요. (This medicine is inefficient - when you mean it doesn't work.)
Right: 이 약은 효과가 없어요. (This medicine is not effective.)

Mistake: 비효율적하다 (Incorrect conjugation).
Correct: 비효율적이다.

Mistake: 비효율적게 (Incorrect adverbial form).
Correct: 비효율적으로.

Mistake: 비효율적인다 (Incorrect plain form).
Correct: 비효율적이다.

Mistake 3: Overuse in Casual Contexts
Using this word too much when complaining to friends can make you sound overly cold or clinical. If a friend takes a long time to get ready, saying '너는 참 비효율적이다' sounds like a robotic performance review. Instead, use '왜 이렇게 오래 걸려?' (Why are you taking so long?).
By avoiding these pitfalls, you can ensure that your use of '비효율적이다' is both grammatically correct and contextually appropriate. Precision in vocabulary is what separates intermediate learners from advanced speakers.
To truly master 비효율적이다, it helps to understand its neighbors in the Korean vocabulary. There are several words that touch upon the idea of waste, lack of results, or poor performance.
비능률적이다 (Ineffective/Inefficient)
This is the closest synonym. While '효율' (efficiency) focuses on the ratio of input to output, '능률' (efficiency/performance) often focuses more on the human or mechanical ability to perform a task quickly. In many cases, they are interchangeable, but '비효율적' is more common in modern business contexts.

Comparison:
- 비효율적이다: Focuses on the waste of resources (money, time).
- 비생산적이다: Focuses on the lack of production or results (unproductive).

낭비다 (It's a waste)
This is a more direct, noun-based way to express inefficiency. '시간 낭비예요' (It's a waste of time) is often used instead of '비효율적이에요' in casual conversation.

Comparison:
- 비효율적이다: Logical critique of a system.
- 소용없다: Emotional or practical statement that something is useless/pointless.

헛수고 (Vain effort)
This is a pure Korean (not Hanja) term. It refers to effort that yields no result at all. '비효율적' implies there was a result, but it cost too much. '헛수고' implies the result was zero.

Comparison:
- 비효율적이다: Formal, objective.
- 비경제적이다: Specifically focuses on financial inefficiency (uneconomical).

Comparison:
- 비효율적이다: Inefficient.
- 불합리하다: Irrational or unreasonable.

Understanding these alternatives allows you to choose the exact shade of meaning you need. While '비효율적이다' is a safe 'catch-all' for inefficiency, knowing when to use '비생산적' or '낭비' will make your Korean sound more natural and nuanced. As you progress, try to notice which of these words native speakers choose in different contexts—it's often the key to sounding like a native.

常见错误
  • Using '비효율적하다' → 비효율적이다

    Words ending in '-적' use the copula '이다', not the verb '하다'.

  • Using it for 'slow' internet. → 인터넷이 느려요.

    Inefficiency involves waste, not just low speed.

  • Confusing with '불편하다'. → 사용하기 불편해요.

    Something can be efficient but hard to use (uncomfortable/inconvenient).

  • Forgetting the '-인' when modifying a noun. → 비효율적인 방법

    You cannot say '비효율적 방법' without the modifier particle '인' in standard Korean.

  • Using it for 'ineffective' medicine. → 효과가 없어요.

    If it doesn't work at all, it's 'ineffective' (비효과적), not 'inefficient'.

小贴士

Adjective vs Noun

Remember that '비효율적' is technically a noun. To use it as an adjective, you must add '이다' (to be) or '-인' (to modify a noun). This is a common pattern for words ending in '-적'.

The 'Bi' Prefix

Learn other '비-' words to expand your vocabulary quickly. 비정상 (abnormal), 비공식 (unofficial), 비인간적 (inhumane). The '비' prefix is a powerful tool for understanding new Korean words.

Pronouncing 'Yul'

The 'u' in 'yul' (율) is a tight sound. Practice saying 'yoo' but keep your lips more tense. If you say it like English 'you-l', it might sound like '열' (yeol) to native speakers.

Office Etiquette

In a Korean office, use '비효율적입니다' to critique a process. It sounds more professional and less like a personal attack than saying someone is doing a bad job.

Essay Structure

In argumentative writing, start by identifying the '비효율성' (inefficiency) and then propose a '해결책' (solution). This is a standard structure for Korean academic writing.

News Keywords

When you hear '비효율적' on the news, it's often followed by words like '예산' (budget), '지출' (spending), or '행정' (administration). This helps you predict the topic.

Hanja Roots

Memorizing the Hanja characters (非 效率 的) will help you recognize this word and its relatives in Japanese and Chinese as well. It's a great 'three-for-one' study deal.

Pali-pali Culture

Understand that 'efficiency' in Korea often means 'speed.' If something is slow, it is almost always labeled as '비효율적이다'.

Synonym Choice

Use '비효율적' for systems and '비생산적' for results. Using the right word shows you are an advanced learner.

Practice with Opposites

Always study '비효율적이다' and '효율적이다' together. Learning antonyms helps create stronger neural pathways for memory.

记住它

记忆技巧

Think of a 'Bee' (비) that is too 'Hyo' (heavy) to fly 'Yul' (well). It's a very 'Inefficient' bee.

视觉联想

Imagine a person trying to cut a large tree with a small plastic butter knife. The contrast between the effort and the result is the essence of '비효율적이다'.

Word Web

Waste Time Money Process Slow Hanja Critique Work

挑战

Try to find three things in your daily routine that are '비효율적이다' and write them down in Korean. For example: '아침에 침대에서 30분 동안 핸드폰을 보는 것은 비효율적이다.'

词源

Derived from Sino-Korean (Hanja) roots. '비' (非) + '효율' (效率) + '적' (的) + '이다'.

原始含义： Not having a high rate of effect/result.

Sino-Korean (Hanja-based)

文化背景

Be careful when using this to describe a person's personality; it can sound very cold and judgmental. It is better to use it for 'methods' or 'systems' rather than 'people'.

In English, 'inefficient' is a common professional term, but in Korean, it carries a slightly stronger tone of 'unnecessary waste' due to the cultural emphasis on speed.

Used frequently in the webtoon and drama 'Misaeng' to describe corporate bureaucracy. A common theme in Korean self-improvement books like 'The Power of Habit' translations. Often used by Korean tech CEOs in interviews when discussing innovation.

It can be, but it sounds very robotic and critical. It is better to use it for a person's *method* or *habit* rather than the person themselves. For example, '그는 비효율적인 사람이다' (He is an inefficient person) sounds like a harsh performance review. Instead, say '그의 일하는 방식은 비효율적이다' (His way of working is inefficient).

'비효율' is a noun meaning 'inefficiency.' '비효율적' is a noun that acts like an adjective meaning 'inefficient.' You use '비효율' when you want to name the problem: '비효율이 발생했다' (Inefficiency occurred). You use '비효율적' to describe something: '이것은 비효율적이다' (This is inefficient).

Not really. Use '인터넷이 느려요' (The internet is slow). '비효율적' would imply the internet is working but using too much electricity or routing data in a weird way. For speed, always use '느리다'.

It is common enough that everyone understands it, but it's more frequent in news, offices, and schools. In casual talk with friends, people often just say '시간 낭비야' (It's a waste of time) or '별로야' (It's not good).

You can use adverbs like '매우' (very), '아주' (very), '정말' (really), or '극도로' (extremely). Example: '정말 비효율적이에요' (It's really inefficient).

The opposite is '효율적이다' (to be efficient). Just remove the '비' (not) prefix.

Only if you are talking about the process of making it or the price. You wouldn't say a sandwich is '비효율적' because it tastes bad. But you could say '이 샌드위치를 만드는 데 3시간이 걸리는 건 비효율적이다' (Taking 3 hours to make this sandwich is inefficient).

Yes, for this specific word. '비효율이다' is grammatically possible but sounds like 'It is inefficiency' rather than 'It is inefficient.' '비효율적이다' is the standard way to use it as an adjective.

It's used for 'inefficient code' (비효율적인 코드) or 'inefficient algorithms' (비효율적인 알고리즘). It means the software uses more RAM or CPU than it should.

There isn't a direct slang word, but people use '노답' (no answer/hopeless) or '뻘짓' (doing something useless) to describe highly inefficient actions.
