الشرح 효능 in your Level:

At the A1 level, you don't need to use the word '효능' (efficacy) yourself, but you might see it on signs or products. Think of it as a fancy way to say 'good for you' or 'works well' specifically for medicine or healthy food. If you see '효능' on a bottle of juice or a pack of vitamins, it's telling you why that item is healthy. For example, it might say '비타민의 효능' which means 'The benefits of Vitamin.' At this level, just remember that if a word starts with '효' (effect), it usually means something is working or has a result. You can use simpler words like '좋아요' (it's good) or '약이에요' (it's medicine). But knowing this word will help you recognize labels in a Korean supermarket or pharmacy. It's like seeing the word 'Efficacy' on a bottle in English—you know it's about how well the product works. Keep it simple: 효능 = what a healthy thing does for your body.

At the A2 level, you are starting to talk more about your health and daily habits. You might use '효능' when explaining why you eat certain foods or take certain vitamins. Instead of just saying 'Ginseng is good,' you can say '인삼은 효능이 많아요' (Ginseng has many benefits/efficacies). This makes your Korean sound a bit more advanced and precise. You will hear this word in commercials for skincare or healthy drinks. It's often used with '있다' (to have) or '없다' (to not have). For example, '이 약은 효능이 없어요' (This medicine isn't working/has no efficacy). You are moving beyond simple descriptions to using specific nouns that describe the quality of things. It's a great word to use when you want to sound like you care about health and wellness, which is a very popular topic in Korea. Try to look for this word on the back of your favorite Korean face mask or snack packet!

At the B1 level, you should be able to distinguish between '효능' (efficacy) and '효과' (effect). You'll use '효능' in more specific contexts, like discussing the medicinal properties of herbs, the benefits of a new diet, or the active ingredients in a beauty product. You might say things like '이 차의 효능이 무엇인가요?' (What is the efficacy/benefit of this tea?). You are also likely to encounter this word in news snippets or blog posts about health. You should begin to use it with more diverse verbs like '나타나다' (to appear/show) or '알려지다' (to be known). For example, '이 식물은 해열 효능이 있는 것으로 알려져 있습니다' (This plant is known to have fever-reducing efficacy). This level requires you to understand that '효능' is not just a general 'result' but a specific 'power' or 'capability' of a substance to heal or improve a condition. It's a key word for navigating a Korean pharmacy or talking about traditional medicine (Hanbang).

At the B2 level, you are expected to use '효능' naturally in discussions about health, science, and consumer products. You understand the nuance that '효능' implies a functional or medicinal capability. You can use it in complex sentences, such as '임상 시험을 통해 이 약의 효능이 입증되었습니다' (The efficacy of this medicine was proven through clinical trials). You should also be familiar with related terms like '자기 효능감' (self-efficacy) in psychological contexts. At this stage, you can compare the '효능' of different products and discuss whether certain health claims are '과장된 효능' (exaggerated efficacy). You are comfortable reading labels and understanding that '효능' refers to the intended medicinal outcome. Your vocabulary is now precise enough to avoid using '효과' when '효능' is more appropriate, especially in formal writing or professional conversations. You might also participate in debates about the '효능' of alternative medicine versus modern medicine.

At the C1 level, your use of '효능' is precise and reflects an understanding of its academic and professional applications. You use it in contexts like pharmaceutical research, public health policy, or advanced nutritional science. You are familiar with collocations like '효능을 극대화하다' (to maximize efficacy) or '효능의 한계' (the limits of efficacy). You can critically analyze reports on the '유효성 및 효능' (effectiveness and efficacy) of new treatments. In professional settings, you might discuss the '정치적 효능감' (political efficacy) of a certain demographic, showing you can apply the concept of 'efficacy' beyond just medicine. Your speech and writing reflect a high degree of lexical precision, choosing '효능' to specifically denote the inherent capacity of a substance or method to achieve a desired functional end. You can also discuss the regulatory aspects of how '효능' must be labeled on products according to Korean law. Your understanding includes the historical and etymological roots of the word.

At the C2 level, you possess a near-native command of '효능' and its various connotations. You can engage in highly technical discussions about pharmacodynamics, where '효능' (efficacy) is distinguished from '효력' (potency) or '유효성' (effectiveness). You understand the philosophical implications of '효능' in traditional East Asian medicine (Hanyak) compared to Western medicine. You can write academic papers or policy briefs where the '효능' of a social program or a medical intervention is evaluated with statistical rigor. You use the word effortlessly in metaphorical ways or within specialized fields like psychology (self-efficacy) or political science (civic efficacy). Your mastery allows you to detect subtle nuances in marketing language, identifying when '효능' is used to imply scientific backing where there may be none. You are an expert at using the word in all registers, from high-level academic discourse to nuanced cultural commentary on Korea's obsession with health and 'well-being' products.

효능 في 30 ثانية

효능 (Hyo-neung) specifically refers to the efficacy or medicinal power of substances like drugs, herbs, and functional foods to produce a beneficial health result.
It is a formal noun commonly used in pharmacies, hospitals, and skincare marketing to describe the intrinsic functional capabilities of a product's active ingredients.
Unlike the general word '효과' (effect), '효능' is reserved for functional/medicinal contexts. You use it when discussing how a substance heals or improves the body.
Commonly paired with verbs like '있다' (to have), '입증하다' (to prove), and '발휘하다' (to exert), it is essential for discussing health and wellness in Korean.

The Korean word 효능 (hyoneung) is a sophisticated noun that translates most accurately to 'efficacy' or 'medicinal effect' in English. While the general word for 'effect' is 효과 (hyogwa), 효능 is specifically reserved for situations involving the intrinsic power of a substance—like a drug, a herb, or a functional food—to produce a healing or beneficial result. When you walk into a Korean pharmacy or a traditional medicine clinic (Hanyiwon), you will see this word everywhere. It describes the 'why' behind a treatment's success. For example, if you are drinking ginger tea to soothe a cold, you are relying on the '효능' of the ginger. It is not just a result; it is the functional capacity of the ingredient itself.

Medical Context: In clinical settings, 효능 refers to the proven capability of a medication to alleviate symptoms or cure a disease under controlled conditions.

이 약은 감기 증상을 완화하는 데 탁월한 효능이 있습니다. (This medicine has excellent efficacy in alleviating cold symptoms.)

Skincare and Beauty: The beauty industry in Korea (K-Beauty) utilizes this term to describe the active ingredients in serums and creams, such as the anti-aging efficacy of retinol.

비타민 C는 피부 미백에 뛰어난 효능을 보입니다. (Vitamin C shows outstanding efficacy in skin brightening.)

Traditional Wisdom: In Korean culture, food is often viewed as medicine (Yak-sik-dong-won), so people frequently discuss the 효능 of seasonal vegetables or herbal teas.

인삼의 주된 효능은 면역력 강화입니다. (The main efficacy of ginseng is strengthening the immune system.)

검증되지 않은 민간요법의 효능을 맹신해서는 안 됩니다. (One should not blindly believe in the efficacy of unverified folk remedies.)

새로운 다이어트 식품의 효능에 대해 의구심이 생깁니다. (Doubts are arising regarding the efficacy of the new diet food.)

Using 효능 correctly requires understanding its role as a noun that often takes the subject or object position. Most commonly, it is paired with the verbs 있다 (to have/exist), 없다 (to not have/exist), 입증하다 (to prove), or 나타내다 (to display). When you want to say something is effective, you say '~의 효능이 있다'. This structure highlights the specific attribute of the subject. For instance, '이 차는 소화에 효능이 있다' (This tea has efficacy for digestion). Notice how the particle '에' is used to indicate the target of the efficacy.

Grammar Pattern: [Noun] + 의 효능: This is the standard possessive form used to describe what the efficacy belongs to. Examples include '약의 효능' (efficacy of medicine) and '성분의 효능' (efficacy of ingredients).

이 화장품은 주름 개선 효능으로 유명합니다. (This cosmetic is famous for its wrinkle-improvement efficacy.)

Scientific and Formal Reporting: In research papers or news reports, you will see '효능을 검증하다' (to verify efficacy) or '효능이 입증되다' (efficacy is proven).

최근 연구에서 이 식물의 항암 효능이 과학적으로 입증되었습니다. (In a recent study, the anti-cancer efficacy of this plant was scientifically proven.)

Comparative Usage: When comparing two products, you might say '효능이 뛰어나다' (efficacy is superior) or '효능이 떨어진다' (efficacy is inferior/lacking).

천연 재료를 사용해서 그런지 약의 효능이 더 빠르게 나타나는 것 같아요. (Perhaps because natural ingredients were used, the medicine's efficacy seems to appear faster.)

과다 복용 시 약의 효능보다는 부작용이 더 클 수 있습니다. (In case of overdose, the side effects can be greater than the efficacy of the medicine.)

이 비타민제는 피로 해소에 탁월한 효능을 발휘합니다. (This vitamin supplement exerts excellent efficacy in fatigue recovery.)

You are most likely to encounter 효능 in professional, commercial, or health-conscious environments. In South Korea, health is a major topic of daily conversation, and the 'efficacy' of various foods (well-being culture) is frequently discussed on television programs like '생로병사의 비밀' (The Secrets of Life, Aging, Illness, and Death). When a celebrity mentions a specific tea they drink for skin health, the internet immediately fills with articles titled '[Ingredient]의 놀라운 효능' (The Amazing Efficacy of [Ingredient]).

TV Home Shopping: Hosts will use high-energy language to describe the '임상적으로 증명된 효능' (clinically proven efficacy) of a new supplement to persuade viewers to buy.

쇼호스트: 여러분, 이 제품의 미백 효능은 이미 수만 건의 후기로 증명되었습니다! (Host: Everyone, the brightening efficacy of this product has already been proven by tens of thousands of reviews!)

Pharmacy and Clinics: Pharmacists explain the 효능 of prescriptions to ensure patients understand how the medicine will help them.

약사: 이 약은 염증을 가라앉히는 효능이 있으니 식후에 꼭 드세요. (Pharmacist: This medicine has efficacy in reducing inflammation, so please take it after meals.)

Product Packaging: On the back of food or cosmetic products, the '효능 및 효과' (Efficacy and Effects) section lists what the product is legally allowed to claim it does.

설명서: 본 제품은 혈액 순환 개선에 도움을 주는 효능이 있습니다. (Manual: This product has efficacy that helps improve blood circulation.)

뉴스: 식약처는 해당 성분의 안정성과 효능을 재검토하기로 했습니다. (News: The Ministry of Food and Drug Safety has decided to re-examine the safety and efficacy of the ingredient in question.)

블로그: 오늘은 탈모 예방에 좋은 검은콩의 효능에 대해 알아보겠습니다. (Blog: Today, let's look into the efficacy of black beans, which are good for preventing hair loss.)

The most frequent mistake learners make is confusing 효능 (hyoneung) with 효과 (hyogwa). While they both relate to 'results,' they are not interchangeable. 효과 is a broad term that applies to anything: the effect of a movie, the effect of a law, or the effect of a joke. 효능 is narrow; it is the *capacity* of a substance to produce a *medicinal* or *functional* result. You wouldn't say a scary movie has '효능'; you would say it has '효과' (the effect of making you scared).

Mistake: Using 효능 for general results: Incorrect: '광고의 효능이 좋았다' (The efficacy of the ad was good). Correct: '광고의 효과가 좋았다' (The effect of the ad was good).

운동의 효능보다는 운동의 '효과'라고 하는 것이 더 자연스러운 경우가 많습니다. (In many cases, it is more natural to say 'effect' of exercise rather than 'efficacy' of exercise, unless referring to physiological functions.)

Mistake: Confusing with 효율 (Efficiency): 효율 (hyoyul) refers to the ratio of output to input (getting a lot done with little effort). 효능 is about the inherent power of a substance.

이 기계는 에너지 효능이 좋다 (X) -> 에너지 '효율'이 좋다 (O). (This machine has good energy efficiency.)

Mistake: Overusing it in casual conversation: While not grammatically wrong, using '효능' when talking about a simple snack might sound too formal. Stick to '몸에 좋다' (good for the body) for very casual settings.

초콜릿의 효능을 논하기보다는 그냥 '초콜릿이 기분 전환에 좋아'라고 말하는 것이 더 일상적입니다. (Rather than discussing the efficacy of chocolate, it's more common to say 'chocolate is good for a mood change.')

약의 효능이 너무 강해서 부작용이 생겼어요. (The efficacy of the medicine was too strong, so side effects occurred.)

비싼 영양제라고 해서 모두 뛰어난 효능을 가진 것은 아닙니다. (Just because it's an expensive supplement doesn't mean it has superior efficacy.)

Understanding synonyms helps you refine your Korean. While 효능 is specific, several related words cover different angles of 'effectiveness.'

효과 (Effect): The most common alternative. Use this for general results. '공부의 효과' (the effect of studying).

성능 (Performance): Used for machines or electronic devices. '컴퓨터의 성능' (the performance of a computer).

유효성 (Validity/Effectiveness): A very formal/academic term used in clinical trials and legal contexts. '백신의 유효성' (the effectiveness of a vaccine).

이 제품은 효능뿐만 아니라 가성비도 좋습니다. (This product has not only efficacy but also good value for money.)

기능 (Function): Refers to what something *does* rather than how *well* it cures. '이 약의 주요 기능은 해열입니다' (The main function of this medicine is reducing fever).

약의 효능을 극대화하기 위해 올바른 복용법을 지켜야 합니다. (To maximize the efficacy of the medicine, you must follow the correct dosage instructions.)

연구진은 새로운 물질의 항균 효능을 발견했습니다. (The research team discovered the antibacterial efficacy of a new substance.)

어떤 사람들에게는 플라세보 효능이 실제로 나타나기도 합니다. (For some people, a placebo efficacy actually appears.)

سهل الخلط

효능 vs 효과 (Effect)

Both translate to 'effect' in many contexts.

효과 is a broad result of any action. 효능 is the specific medicinal or functional capacity of a substance. You can see the '효과' of a movie, but not its '효능'.

약의 효능 덕분에 치료 효과가 나타났다. (Thanks to the efficacy of the medicine, the treatment effect appeared.)

효능 vs 효율 (Efficiency)

Both start with '효' and relate to things working well.

효율 is about how much you get out of what you put in (e.g., fuel efficiency). 효능 is about whether something works to produce a specific functional result.

작업 효율을 높이려면 좋은 도구가 필요하다. (To increase work efficiency, good tools are needed.)

효능 vs 성능 (Performance)

Both describe how well something works.

성능 is exclusively for machines, computers, or mechanical systems. 효능 is for biological or chemical substances.

이 자동차는 엔진 성능이 뛰어나다. (This car has excellent engine performance.)

효능 vs 효력 (Potency/Validity)

Both relate to the power of a substance or rule.

효력 often refers to the legal validity of a document or the sheer strength/potency of a drug's action. 효능 is the general capability to produce the desired benefit.

이 법은 내일부터 효력이 발생한다. (This law becomes valid from tomorrow.)

효능 vs 기능 (Function)

Both describe what something does.

기능 is the neutral description of a role or task. 효능 is the positive, beneficial result of that function.

이 약의 기능은 혈압을 낮추는 것이다. (The function of this medicine is to lower blood pressure.)

نصائح

Think Pharmacy

Whenever you are in a pharmacy or looking at a medicine box, look for '효능'. It's the standard term for what the medicine is meant to treat.

Use with '에'

Always use the particle '에' to link the efficacy to the problem it solves. '감기에 효능' (efficacy for a cold), '두통에 효능' (efficacy for a headache).

Substance vs. Action

If a substance (pill, tea, cream) works, use '효능'. If an action (studying, running, laughing) works, use '효과'.

Spot the Ad

Korean ads love the word '탁월한 효능' (excellent efficacy). If you hear '탁월한' (tak-wol-han), the next word is almost certainly '효능'.

Self-Efficacy

Learn '자기 효능감' as a set phrase. It's a high-level term that will impress native speakers in discussions about mindset and success.

Hanbang Context

In traditional Korean medicine, '효능' is used to describe the 'nature' of herbs (e.g., warming efficacy, cooling efficacy).

Sound Smart

Using '효능' instead of '좋은 점' when discussing health makes you sound like a more educated, upper-intermediate speaker.

The Power Within

Visualize '효능' as a hidden battery inside an object. It's the internal power source that makes the object useful.

Compare Efficacies

Use '효능이 더 좋다' (efficacy is better) or '효능이 떨어진다' (efficacy is inferior) when comparing two health products.

Avoid Placeholder '효과'

Don't get lazy and use '효과' for everything. If it's about medicine or functional food, '효능' is the mark of a pro.

احفظها

وسيلة تذكّر

Think of 'Hyo' as 'High' and 'Neung' as 'New Energy'. If a medicine has 'Hyo-neung', it gives you High New Energy because it works so well!

ربط بصري

Imagine a superhero cape inside a medicine bottle. The '효능' is the superpower that the medicine possesses.

تحدٍّ

Go to a Korean grocery store or look up a Korean skincare product online. Find the word '효능' on the label and translate the sentence it is in.

أصل الكلمة

The word is derived from Hanja (Sino-Korean characters). 效 (효) means 'to follow' or 'effect/result,' and 能 (능) means 'ability' or 'power.' Together, they literally mean 'the power to produce a result.'

المعنى الأصلي: The inherent ability of a substance to achieve a specific, intended outcome.

Sino-Korean

السياق الثقافي

Be careful not to claim '효능' for unverified products in a professional setting, as South Korean law has strict regulations on advertising medical efficacy.

In English, we often use 'benefits' or 'what it's good for' in casual talk. 'Efficacy' sounds very medical. In Korean, '효능' is common in both casual health talk and medical talk.

Korean TV show 'Secrets of Life, Aging, and Death' frequently uses this word. K-Beauty marketing campaigns for brands like Sulwhasoo emphasize the 효능 of herbal ingredients. The psychological concept of 'Self-Efficacy' (자기 효능감) is a popular topic in Korean self-help books.
