解説 적합성 in your Level:

At the A1 level, '적합성' (jeok-hap-seong) is a very difficult word because it is formal and abstract. However, you can think of it simply as 'being good for something.' Imagine you have a key and a lock. If the key fits, it has '적합성.' You won't use this word often when you first start learning Korean. Instead, you will use simple words like '좋아요' (it's good) or '맞아요' (it's correct/it fits). If you see this word, just remember it means 'fitting well' or 'being suitable.' It is like saying 'This is the right thing for this job.' For example, if you are choosing a coat for winter, a warm coat has '적합성' for the cold weather. Don't worry about using it in your own sentences yet; just try to recognize it as a word for 'suitability.'

At the A2 level, you are starting to learn more specific nouns. '적합성' is a noun that comes from the adjective '적합하다' (to be suitable). The '-성' at the end is like '-ness' in English. So, '적합성' is 'suitability-ness.' You might see this word in simple news titles or on signs. It is used when someone is checking if something is 'right' for a purpose. For example, if you are looking for a job, the boss checks your '적합성' (suitability). Are you the right person? Do you have the right skills? You can use the pattern '[Noun] + 에 적합해요' (It is suitable for [Noun]) more easily than the noun '적합성.' But knowing the noun will help you understand more formal Korean writing.

At the B1 level, you should begin to incorporate '적합성' into your formal writing and professional vocabulary. This word is essential for discussing topics like employment, environment, and technology. You should understand that it is a 'high-level' word for 'fit.' Instead of saying '이게 여기에 잘 맞아요' (This fits well here), you can say '이것의 적합성을 확인해야 합니다' (We need to check the suitability of this). This makes you sound much more professional. You will often see it used with particles like '에 대한' (regarding). For example, '기후에 대한 적합성' (suitability for the climate). Practice identifying this word in news articles or office emails. It is a key word for expressing objective evaluation rather than just personal opinion.

At the B2 level, '적합성' is a word you are expected to use accurately in various contexts. You should be able to distinguish it from similar words like '적절성' (appropriateness) or '타당성' (validity). '적합성' specifically refers to functional or technical fitness. For instance, in a business presentation, you might talk about '시장 적합성' (market fit). In an essay about the environment, you might discuss the '생태적 적합성' (ecological suitability) of a certain policy. You should also be comfortable using collocations like '적합성을 평가하다' (to evaluate suitability) or '적합성이 떨어지다' (to lack suitability). This word is a hallmark of the 'Upper Intermediate' level, showing that you can handle abstract, Sino-Korean vocabulary (Hanja) effectively.

At the C1 level, you should have a nuanced understanding of '적합성' and its role in academic and technical discourse. You should be able to use it to discuss complex systems, such as '법적 적합성' (legal admissibility/suitability) or '논리적 적합성' (logical congruence). At this level, you recognize that '적합성' is often part of a larger framework of evaluation metrics. You might analyze the '적합성' of a research methodology in a thesis or a high-level report. You should also be aware of its antonym '부적합성' and related terms like '최적성' (optimality). Your usage should be precise, using the word to describe the structural or functional alignment of components within a system. You can also use it metaphorically in literary analysis to discuss the '시대적 적합성' of a character's actions.

At the C2 level, you possess a native-like grasp of '적합성,' including its etymological roots and its placement within the vast landscape of Korean formal vocabulary. You can use it in highly specialized fields, such as '알고리즘 적합성' (algorithmic fitness) in computer science or '헌법 적합성' (constitutional suitability/conformity) in law. You understand the subtle rhetorical power of the word—how using '적합성' instead of '좋음' or '맞음' shifts a discussion from the subjective to the objective and authoritative. You can engage in deep philosophical or technical debates where the '적합성' of a paradigm is being questioned. Your ability to use this word, along with its various compound forms and related Hanja-based synonyms, allows you to communicate at the highest professional and academic levels in Korea.

적합성 30秒で

적합성 means suitability or fitness for a purpose.
Used in formal contexts like business, science, and law.
Commonly paired with '평가하다' (evaluate) or '검토하다' (review).
Derived from Hanja: 適 (suit) + 合 (fit) + 性 (quality).

The Korean word 적합성 (Jeok-hap-seong) is a formal noun that translates to 'suitability,' 'fitness,' or 'appropriateness.' It is composed of three Hanja characters: 適 (적 - to suit), 合 (합 - to join/fit), and 性 (성 - nature/quality). Together, they describe the inherent quality of something being perfectly aligned with a specific purpose, standard, or environment. While in English we might use 'suitability' in both casual and formal contexts, in Korean, 적합성 carries a weight of objective evaluation. It is frequently used in professional, academic, and technical settings to discuss whether a person, a material, or a strategy meets the necessary criteria for a given task.

Professional Context: In human resources, managers often assess the 직무 적합성 (job suitability) of a candidate. This refers to how well their skills and personality match the requirements of the role.

이번 지원자의 가장 큰 장점은 직무 적합성이 매우 높다는 것입니다. (The biggest advantage of this applicant is that their job suitability is very high.)

Beyond the workplace, 적합성 is a key term in scientific research and engineering. When testing a new material for a bridge, engineers look for 재료의 적합성 (suitability of the material) to ensure it can withstand environmental stress. It implies a rigorous comparison against a set of benchmarks. If something lacks 적합성, it is deemed '부적합' (unsuitable). This word is also pivotal in legal and policy discussions, where laws are evaluated for their 사회적 적합성 (social suitability) or relevance to current cultural norms.

Environmental Context: Biologists use this term to describe how well an organism fits into its ecological niche, though '적응성' (adaptability) is also used, '적합성' focuses on the current state of being fit.

기후 변화에 따른 식생의 적합성을 조사하고 있습니다. (We are investigating the suitability of vegetation according to climate change.)

In daily life, you might encounter this word when reading product reviews or government announcements. If a new regulation is passed, the public might debate its 현실 적합성 (practical suitability or realism). It asks: 'Does this actually work in the real world?' This nuance makes it a powerful word for critical thinking and analysis in Korean conversations. It is not just about being 'good' or 'bad,' but about the precision of the match between a thing and its intended use.

Technical Context: In software development, 'UI/UX 적합성' refers to how well the interface suits the user's needs and behaviors.

이 앱의 인터페이스는 고령 사용자들의 적합성을 고려하여 설계되었습니다. (This app's interface was designed considering the suitability for elderly users.)

Using 적합성 correctly requires understanding its grammatical placement as a formal noun. It is most frequently paired with the particle ~에 대한 (regarding/for) or ~의 (possessive). Because it describes a state or quality, it is often the object of verbs like 평가하다 (to evaluate), 검토하다 (to review), 판단하다 (to judge), or 높이다 (to heighten/increase). Mastery of this word allows you to articulate complex evaluations of systems and people with precision.

Evaluation Pattern: [Target] + 에 대한 + 적합성 + 을/를 + [Verb]. This is the standard way to say you are checking if something is suitable.

정부는 새로운 교육 정책의 적합성을 심도 있게 논의했습니다. (The government deeply discussed the suitability of the new education policy.)

Another common usage is as a compound noun. Korean language loves combining nouns to create specific terms. You will often see 직무 적합성 (job suitability), 시장 적합성 (market fit), or 환경 적합성 (environmental suitability). In these cases, the space between the nouns is often omitted in professional writing. This structure is efficient and sounds highly educated. When you want to say something matches or fits, you can use the verb 적합하다, but when discussing the concept of that fit, you must use 적합성.

Improvement Pattern: [Noun] + 의 적합성을 높이다. This means to improve or increase the suitability of something.

우리는 제품의 시장 적합성을 높이기 위해 디자인을 수정했습니다. (We modified the design to increase the product's market suitability/fit.)

In passive or descriptive sentences, you might see 적합성이 떨어지다 (to lack suitability/suitability drops) or 적합성이 인정되다 (suitability is recognized). These phrases are common in legal documents or official reports. For example, '이 증거는 법적 적합성이 떨어집니다' (This evidence lacks legal suitability/admissibility). Understanding these collocations is the difference between sounding like a beginner and sounding like a native speaker in a business environment. It allows you to move away from simple words like '좋다' (good) or '맞다' (correct) towards more nuanced analytical language.

Comparison Pattern: A와 B의 적합성을 비교하다. This is used when comparing which of two options is more suitable for a task.

두 후보지의 입지 적합성을 비교해 본 결과, A 지역이 더 우수했습니다. (As a result of comparing the location suitability of the two candidate sites, Area A was superior.)

If you are watching Korean news or reading a newspaper like the Chosun Ilbo or Hankyoreh, you will encounter 적합성 almost daily. It is a staple of political and economic discourse. For instance, when the Bank of Korea discusses interest rates, they might talk about the 통화 정책의 적합성 (suitability of monetary policy). In this context, it isn't just a word; it's a metric of success. Listening for this word in news broadcasts will help you identify the core argument of an editorial or a report.

Corporate Meetings: During project planning or strategy sessions, Korean professionals use this word to vet ideas. It’s part of the 'logic' of Korean business culture.

이번 마케팅 전략이 우리 브랜드 이미지와 적합성이 있는지 다시 한번 확인합시다. (Let's check once more if this marketing strategy has suitability with our brand image.)

In the academic world, specifically in social sciences and humanities, 적합성 is used to discuss the validity of a theory or a research method. If you are a student in Korea, you will see this word in your textbooks and professors' lectures. It is often paired with 타당성 (validity) and 신뢰성 (reliability). In a thesis, you might write about the 연구 모델의 적합성 (suitability of the research model). Hearing this word in a university setting signals that a serious evaluation of methodology is taking place.

Legal and Administrative: Government offices use this word in forms and official guidelines. For example, '건축 적합성 검사' (Construction suitability inspection).

해당 부지는 공장 설립에 대한 적합성 판정을 받았습니다. (The site in question has received a suitability ruling for factory establishment.)

Lastly, you will hear this in documentary narrations or educational programs. When discussing evolution, a narrator might talk about an animal's 환경 적합성. In documentaries about history, they might discuss the 시대적 적합성 (suitability for the era) of a certain political move. It is a word that provides a 'bird's eye view' of a situation, looking at the big picture of how things fit together. If you hear someone using 적합성 in a casual setting, they are likely trying to sound very logical, persuasive, or perhaps a bit overly formal.

Product Reviews: Tech reviewers often talk about '용도 적합성'—whether a gadget is actually suitable for its intended use case.

이 노트북은 게이밍용으로는 적합성이 다소 떨어집니다. (This laptop is somewhat lacking in suitability for gaming purposes.)

One of the most frequent mistakes learners make is confusing 적합성 (Suitability) with 적절성 (Appropriateness). While they are close synonyms, they are used in different nuances. 적합성 is more about 'fitness for a specific function or standard,' whereas 적절성 is more about 'social or situational appropriateness.' For example, wearing a suit to a wedding is 적절하다 (appropriate), but a material being strong enough for a bridge is 적합하다 (suitable/fit).

Mistake: Overusing it in casual speech: Using '적합성' when talking to friends about dinner choices. It sounds too stiff.

오늘 저녁 메뉴의 적합성을 따져보자. (Incorrect: Let's weigh the suitability of today's dinner menu.) -> 오늘 뭐 먹는 게 좋을까? (Better: What should we eat today?)

Another error involves the choice of particles. Some learners use ~를 적합성 instead of ~에 대한 적합성. Remember that 적합성 is a noun describing a relationship to something else. Therefore, you need the 'towards/for' particle 에 대한 or 에. Forgetting this makes the sentence grammatically disjointed. Additionally, don't confuse it with 정확성 (accuracy). Something can be perfectly accurate but completely unsuitable for the purpose at hand.

Confusing with '가능성' (Possibility): Sometimes learners use '적합성' when they mean whether something is possible. Suitability is about 'quality of fit', not 'chance of happening'.

그가 올 적합성이 있어요. (Incorrect: There is a suitability of him coming.) -> 그가 올 가능성이 있어요. (Correct: There is a possibility of him coming.)

Lastly, be careful with the word 개연성 (probability/consistency). In literature or film criticism, people often talk about the 개연성 of a plot (whether it makes sense within the story). Beginners might mistakenly use 적합성 here. While a plot might be 'suitable' for a genre, 개연성 is the specific term for narrative logic. Keeping these distinctions clear will help you sound much more sophisticated in your Korean writing and speaking.

Spelling Note: Make sure not to write '적합선' (which would mean 'suitable line'). The '성' (quality) is essential.

기술적 적합성을 검증하는 단계입니다. (It is the stage of verifying technical suitability.)

To truly master 적합성, you should understand the words that surround it in the same semantic field. Korean has a rich vocabulary for expressing 'fitness' and 'correctness,' and choosing the right one depends on the context. The most common alternative is 적절성, but there are others like 타당성, 합당성, and 부합성. Each of these has a specific flavor that changes the meaning of your sentence slightly.

적합성 vs. 적절성: 적합성: Functional fitness, technical suitability (e.g., a key fitting a lock).
적절성: Contextual appropriateness, social rightness (e.g., saying the right thing at a funeral).

이 기계는 고온 환경에 적합성이 높지만, 가격의 적절성은 의문입니다. (This machine has high suitability for high-temperature environments, but the appropriateness of the price is questionable.)

Another important word is 타당성 (validity/feasibility). While 적합성 asks 'Does it fit?', 타당성 asks 'Is it logical or doable?' In business, a 타당성 조사 (feasibility study) is done before a project starts to see if it makes financial sense. 합당성 is more about 'rightfulness' or 'justness,' often used in legal or moral debates. Finally, 부합성 refers to how well something 'corresponds' or 'matches up' with a specific standard or statement.

적합성 vs. 타당성: 적합성: Focuses on the 'fit' between two things.
타당성: Focuses on the 'logic' or 'reasonableness' of the thing itself.

계획의 타당성은 검증되었으나, 실행 인력의 적합성이 부족합니다. (The validity of the plan was verified, but the suitability of the execution personnel is lacking.)

When you want to emphasize that something is 'perfectly' suited, you can use the phrase 최적성 (optimality). This is the 'superlative' version of 적합성. In computer science or mathematics, finding the 최적의 솔루션 (optimal solution) is the goal. Understanding these subtle shifts in vocabulary will allow you to describe reality with much higher resolution. Instead of just saying things are 'good,' you can specify if they are suitable, valid, appropriate, or optimal.

Antonyms: The direct opposite is 부적합성 (unsuitability). Other related terms include 불일치 (mismatch) or 어긋남 (discrepancy).

데이터의 부적합성 때문에 연구 결과가 무효화되었습니다. (The research results were invalidated due to the unsuitability of the data.)

よくある間違い

Using '적합성해요' as a verb. → 적합합니다 / 적합성이 있습니다.
적합성 is a noun. To use it as a verb, you must use the adjective form '적합하다' or the phrase '적합성이 있다'.
Confusing it with '정확성' (Accuracy). → 적합성 (Suitability).
Accuracy is being correct. Suitability is being the right fit. A hammer is accurate but not suitable for eating soup.
Using the wrong particle: '를 적합성'. → 에 대한 적합성 / 의 적합성.
Suitability is always *of* something or *for* something. Use possessive or directional particles.
Using '적합성' for personal feelings. → 마음에 들어요 / 좋아요.
적합성 is an objective evaluation. For subjective 'liking,' use simple emotional verbs.
Confusing '적합성' with '가능성'. → 적합성 (Fitness) vs 가능성 (Possibility).
Saying 'He has suitability to come' is wrong. You mean 'He has the possibility of coming.'

ヒント

Suffix -성

The suffix '-성' is very productive in Korean. If you know '적합' (suitable), you can guess '적합성' is 'suitability.' Look for this pattern in other words like '중요' (important) -> '중요성' (importance).

Job Seekers

If you are writing a resume in Korean, use '직무 적합성' to describe how your experience matches the job description. It is a powerful keyword for HR managers.

Business Meetings

Instead of saying 'I like this idea,' say '이 아이디어는 우리 목표에 대한 적합성이 높습니다.' It sounds more objective and persuasive.

Academic Tone

Use '적합성을 검증하다' (verify suitability) to give your research papers a more professional and academic tone.

Pronunciation

Remember the 'p' in 'hap' makes the 's' in 'seong' sound like 'ss'. It's [적합썽]. Practicing this will make your speech sound more natural.

Fit vs. Appropriate

Use '적합성' for functional things (tools, candidates, materials) and '적절성' for social things (words, timing, behavior).

News Headlines

When you see '적합성' in a headline, the article is likely about an evaluation, a controversy over a candidate, or a policy review.

The 'Hap' Connection

Connect 'Hap' (合) to 'Harmony' or 'Joining.' Suitability is about things joining together in harmony.

Formal Lectures

Professors love this word. If you hear it, they are likely discussing the 'criteria' for something.

Don't Overuse

In casual settings, stick to simple verbs like '맞다' or '어울리다.' Overusing '적합성' can make you seem unapproachable.

暗記しよう

記憶術

Think of 'Jeok' as 'Jock' (an athlete). A jock needs to have the right 'Hap' (fitness) and 'Seong' (soul/nature) for the sport. Jock-Hap-Seong = Suitability for the game.

視覚的連想

Visualize a puzzle piece (적합) that has a certain glow or quality (성) because it fits perfectly into the empty space.

チャレンジ

Try to use '적합성' in a sentence today when talking about a movie or a book. Ask: '이 영화의 결말이 주제와 적합성이 있나요?' (Does the ending of this movie have suitability with the theme?)

語源

The word is a Sino-Korean compound. '적' (適) means to follow or suit. '합' (合) means to join or fit together. '성' (性) is a suffix meaning nature, quality, or property.

元の意味： The quality of fitting together or suiting a standard.

Sino-Korean (Hanja)

文化的な背景

No specific sensitivities, but using it in very casual settings can make you sound cold or overly clinical.

English speakers might use 'fit' or 'suitability,' but '적합성' is much more formal than 'fit.' It sounds like 'admissibility' or 'congruence' in some contexts.

Used frequently in the 'Job Suitability' sections of the CSAT (Suneung) exams. A common term in 'KBS News' when discussing government policy changes. Found in the 'Terms of Service' of many Korean tech giants like Kakao or Naver.

よくある質問

Technically yes, but it sounds very clinical. You might say '등산에 대한 의류의 적합성' in a product test report. In a store, just say '이 옷 잘 어울려요?' (Does this suit me?) or '이 옷 등산할 때 입기 좋아요?' (Is this good for hiking?).

It is the Korean translation of 'Market Fit' (specifically Product-Market Fit). It means how well a product satisfies a strong market demand.

While not a common religious term, it can be used in theological discussions regarding the 'suitability' of a sacrifice or a law in modern times.

Usually '~에 대한' (regarding) or '~의' (possessive). For example: '환경에 대한 적합성' or '계획의 적합성.'

Yes, it appears frequently in the Korean language and Social Studies sections when discussing the validity of research or policies.
