At the A1 level, '기능하다' is a bit difficult. Think of it as a fancy way to say 'to work' or 'to do its job.' Imagine your phone. It has many parts. The camera 'functions' to take pictures. The screen 'functions' to show you videos. In A1, we usually use simpler words like '해요' (do) or '잘 돼요' (works well). But if you see '기능하다', just remember it means something is doing what it is supposed to do in a system. For example, 'This button functions.' It is a formal word, so you might see it in a simple instruction manual. It comes from '기능' (function) and '하다' (to do). So, 'function-do.'
At the A2 level, you can start using '기능하다' to describe the parts of things. For example, 'The heart functions' or 'The computer functions.' It is more formal than '작동하다' (to work/operate). You might use it when talking about your body or a machine in a classroom setting. A good way to remember it is by using the pattern 'A는 B로서 기능해요' which means 'A functions as B.' For example, 'My phone functions as a clock.' This helps you describe the purpose of things more clearly than just saying 'I use my phone as a clock.' It shows you understand that things have specific roles.
At the B1 level, '기능하다' becomes useful for discussing social and technical systems. You can use it to describe how a library functions as a community center or how a specific law functions to protect people. You should distinguish it from '작동하다' (mechanical operation). While a car '작동하다' (starts/runs), its seatbelt '기능하다' (functions) to keep you safe. You will start seeing this word in news articles and intermediate reading passages. It often appears with adverbs like '정상적으로' (normally) or '제대로' (properly). It's a key word for moving from basic descriptions to more analytical ones.
At the B2 level, you are expected to use '기능하다' in academic and professional contexts. It is essential for explaining complex systems where multiple parts work together. You should be able to use it to describe abstract concepts, such as how 'social media functions as a double-edged sword.' At this level, you should also understand its relationship with nouns like '기능성' (functionality) and '기능적' (functional). You will encounter it in discussions about economics, sociology, and advanced technology. It is often used to describe the 'failure' of a system (기능을 상실하다 - to lose function) or its 'recovery' (기능을 회복하다).
At the C1 level, '기능하다' is used to analyze the structural and systemic roles of entities within a discourse. You will use it to discuss the nuanced roles of institutions, such as how the judiciary functions as a check on executive power. It is frequently paired with sophisticated adverbs like '유기적으로' (organically), '중추적으로' (pivotally), or '상호보완적으로' (complementarily). You should be able to distinguish it from '작용하다' (to act/affect) and '수행하다' (to perform) with precision. In C1 writing, '기능하다' helps in constructing logical arguments about the utility and purpose of various social or scientific phenomena.
At the C2 level, '기능하다' is a fundamental tool for high-level philosophical, technical, and literary analysis. You might use it to describe how a metaphor functions within a poem or how a specific historical event functioned as a catalyst for social change. The word is used to explore the teleology (purpose) of systems. You will understand its usage in highly specialized fields, such as 'functionalism' in sociology or 'functional programming' in computer science. At this level, the word is not just about 'working' but about the essential reason for an entity's existence within a complex, multifaceted reality. You can use it to critique whether an institution is truly 'functioning' according to its stated ideals.

기능하다 in 30 Sekunden

  • 기능하다 means to perform a specific role or function within a system, whether biological, technical, or social, focusing on purpose rather than just movement.
  • It is a formal verb often used with '~로서' (as) to define the identity or utility of the subject in a larger context.
  • Commonly found in academic, medical, and news contexts, it distinguishes itself from '작동하다' (mechanical operation) by emphasizing the systemic contribution of the subject.
  • Correct usage involves intransitive patterns, typically paired with adverbs like '정상적으로' (normally) or '유기적으로' (organically) to describe the quality of the performance.

The Korean verb 기능하다 (ginunghada) is a sophisticated term primarily used to describe the act of fulfilling a specific role, purpose, or function within a larger system. Unlike the simple verb 'to work' (일하다) or 'to operate' (작동하다), 기능하다 implies a systemic relationship where the subject is a component contributing to a whole. It is derived from the noun 기능 (機能), meaning 'function' or 'faculty,' and the auxiliary verb 하다. In essence, when something '기능한다', it isn't just moving; it is performing the specific duty it was designed or evolved to do.

Systemic Utility
It describes how a part serves the whole, such as an organ in a body or a department in a corporation.
Abstract Roles
It is often used for abstract concepts, like how a law functions as a deterrent or how a park functions as a social hub.

이 기계는 비상시에만 기능하도록 설계되었습니다. (This machine is designed to function only in emergencies.)

In biological contexts, you might hear about how the heart functions to pump blood. In sociological contexts, you might discuss how schools function as agents of socialization. The word carries a formal tone, making it a staple in academic writing, technical manuals, and news reports. It suggests a level of structural necessity; if something fails to 기능하다, the entire system might collapse or become inefficient.

간이 정상적으로 기능하지 않으면 건강에 치명적입니다. (If the liver does not function normally, it is fatal to health.)

Furthermore, 기능하다 often appears with the particle '~로서' (as), indicating the specific capacity in which something is functioning. For example, '언어는 소통의 수단으로서 기능한다' (Language functions as a means of communication). This highlights the functional identity of the subject within a specific context.

이 공간은 지역 주민들을 위한 쉼터로서 기능하고 있습니다. (This space is functioning as a shelter for local residents.)

Technical Nuance
In software engineering, it refers to a module performing its designated logic within the application architecture.

새로운 업데이트 이후 검색 엔진이 제대로 기능하지 않습니다. (The search engine has not been functioning properly since the new update.)

In summary, 기능하다 is about the 'why' and 'how' of a component's existence within a structure. It is less about the mechanical movement and more about the fulfillment of a purpose. Whether it's a biological organ, a social institution, or a piece of software, 기능하다 describes the active state of being useful and purposeful.

가족은 사회의 가장 기본적인 단위로서 기능합니다. (The family functions as the most basic unit of society.)

Using 기능하다 correctly requires understanding its formal register and its typical grammatical companions. It is an intransitive verb, meaning it does not take a direct object with '을/를'. Instead, the thing that is functioning is the subject (이/가), and the role it plays is often marked by '로서' (as) or '으로' (as/into).

Grammar Pattern 1: [Subject] + [Adverb] + 기능하다
Commonly used with adverbs like '정상적으로' (normally), '원활하게' (smoothly), or '제대로' (properly).

정부는 경제가 원활하게 기능하도록 지원해야 합니다. (The government must provide support so that the economy functions smoothly.)

When discussing the purpose of an object, you will frequently see the construction '~로서 기능하다'. This is the most common way to express 'to function as'. It identifies the identity or role the subject assumes within a context.

Grammar Pattern 2: [Subject] + [Noun]로서 기능하다
This highlights the specific role. For example, '교육은 계층 이동의 사다리로서 기능한다' (Education functions as a ladder for social mobility).

이 건물은 박물관이자 교육 센터로서 기능하고 있습니다. (This building is functioning as both a museum and an education center.)

In negative contexts, it is often used to describe systemic failure. Instead of saying something is 'broken' (고장 나다), saying it 'does not function' (기능하지 못하다) suggests a more serious, structural issue. This is common in medical or political discourse.

민주주의가 제대로 기능하지 못할 때 부패가 발생합니다. (Corruption occurs when democracy does not function properly.)

Collocations
Commonly paired with: 정상적으로 (normally), 사회적으로 (socially), 유기적으로 (organically), 핵심적으로 (centrally).

각 부서가 유기적으로 기능해야 프로젝트가 성공합니다. (Each department must function organically for the project to succeed.)

Finally, remember that '기능하다' is a stative-like action verb. It describes an ongoing state of performance. Therefore, it is frequently used in the present progressive form (~고 있다) to describe current roles or in the potential form (~ㄹ 수 있다) to describe capabilities.

이 앱은 오프라인에서도 핵심 기능들이 기능할 수 있습니다. (The core functions of this app can function even offline.)

You will encounter 기능하다 in environments that require precision, formality, and structural analysis. It is not a word you would typically use while chatting with friends about a broken toaster, but it is exactly what you would hear in a documentary about how that toaster was engineered or in a news report about a power grid failure.

News & Media
Journalists use it to describe the state of public institutions, economic markets, or international treaties.

국회가 마비되어 입법 기관으로서 전혀 기능하지 못하고 있습니다. (The National Assembly is paralyzed and not functioning as a legislative body at all.)

In academic settings, particularly in the sciences and social sciences, 기능하다 is indispensable. Professors and researchers use it to explain how biological systems maintain homeostasis or how social structures maintain order. If you are reading a Korean textbook on biology, sociology, or economics, you will see this word on almost every page.

Medical & Scientific Contexts
Used to describe the physiological performance of organs, cells, and enzymes.

뇌의 특정 부위가 기능하는 방식을 연구하고 있습니다. (We are studying the way specific parts of the brain function.)

In the corporate world, 기능하다 is used during strategy meetings or performance reviews. It describes how departments or specific roles contribute to the company's overall goals. It sounds much more professional than saying '일을 하다' (to do work).

우리 팀은 마케팅 전략의 핵심 허브로서 기능해야 합니다. (Our team must function as the core hub of the marketing strategy.)

Technology & IT
Used in software documentation to explain what a specific feature or API endpoint does.

이 플러그인은 보안 강화 도구로서 기능합니다. (This plugin functions as a security enhancement tool.)

Lastly, you'll hear it in legal or administrative contexts. When a law or a committee is established, its 'function' is defined using this verb. It establishes the legal boundaries of what that entity is supposed to do.

이 위원회는 자문 기구로서만 기능할 뿐, 결정권은 없습니다. (This committee only functions as an advisory body and has no decision-making power.)

While 기능하다 is a powerful word, learners often misuse it by confusing it with similar-sounding or similar-meaning verbs. The most common error is using it where 작동하다 (to operate/work) is more appropriate. 작동하다 is used for the mechanical 'on/off' state of a machine, while 기능하다 is about the purpose it serves.

Error 1: Confusing with 작동하다
Incorrect: '컴퓨터가 기능하지 않아요' (The computer doesn't function - sounds like it's missing its purpose). Correct: '컴퓨터가 작동하지 않아요' (The computer won't turn on/work).

리모컨이 작동하지 않는 것 같아요. (The remote doesn't seem to be working/operating.)

Another common mistake is confusing 기능하다 with 작용하다 (to act/affect). 작용하다 is used when one thing exerts an influence on another, like a medicine acting on a virus or gravity acting on an object. 기능하다 is internal to the subject's role.

Error 2: Confusing with 작용하다
Incorrect: '이 약은 해열제로 기능합니다' (This medicine functions as a fever reducer - acceptable but '작용합니다' is better for chemical effects).

중력은 모든 물체에 작용합니다. (Gravity acts upon all objects.)

Learners also sometimes try to use 기능하다 with human subjects in a casual way. You shouldn't say '나는 선생님으로 기능해요' to mean 'I work as a teacher.' This sounds like you are a robot or a component in a machine. Instead, use '일하다' or '교직에 있다'. 기능하다 is for systems, organs, or abstract roles.

Error 3: Over-formalizing Human Roles
Avoid using it for individual human jobs unless you are talking about a person's role within a specific organizational structure in a very technical sense.

그는 팀에서 리더로서 역할을 하고 있습니다. (He is playing a role as a leader in the team - better than '기능하고'.)

Finally, ensure you are using the correct particle. It is almost always '~로서' (as a status/role) and not '~로써' (as a tool/means), although this is a common mistake even for native speakers. Since '기능하다' usually refers to a role or identity, '로서' is the grammatically correct choice.

이 공원은 도시의 허파로서 기능합니다. (This park functions as the lungs of the city.)

Understanding the nuances between 기능하다 and its synonyms will help you choose the right word for the right context. While they all relate to 'working' or 'doing,' their specific applications vary significantly.

작동하다 (To Operate)
Focuses on the mechanical or electronic movement. A machine '작동한다' when it's turned on and running. '기능하다' is what that running achieves.
작용하다 (To Act/Affect)
Focuses on the influence or effect one thing has on another. It's about interaction and impact.
역할을 하다 (To Play a Role)
This is the more natural, less formal version of '기능하다'. It is used for both people and objects.

비타민 C는 항산화제로서 작용합니다. (Vitamin C acts as an antioxidant - focus on the chemical effect.)

When comparing 기능하다 and 수행하다 (to carry out/perform), 수행하다 is more active and task-oriented. You '수행하다' a mission or a duty. 기능하다 is more about the inherent state of being functional within a system.

수행하다 vs 기능하다
수행하다 is 'doing a task'; 기능하다 is 'serving a purpose'.

컴퓨터가 복잡한 계산을 수행하고 있습니다. (The computer is performing complex calculations.)

In technical documentation, you might also see 구동하다 (to drive/run). This is specifically for starting up software or engines. Once a system is '구동' (driven/started), it then '기능' (functions) to provide services to the user.

새로운 운영체제는 저사양 PC에서도 잘 구동됩니다. (The new OS runs well even on low-spec PCs.)

Lastly, 활약하다 (to be active/play a great part) is a more dynamic and positive synonym, usually used for people in sports or business who are doing an exceptionally good job. 기능하다 is neutral and systemic.

그 선수는 이번 경기에서 공격수로서 크게 활약했습니다. (That player played a great part as a forward in this game.)

Häufig gestellte Fragen

10 Fragen

It is rare and sounds robotic. Use '역할을 하다' instead. However, in a very technical organizational chart discussion, you might say a person 'functions as a coordinator,' but it's still very formal.

작동하다 is about the mechanics (the engine is running). 기능하다 is about the purpose (the engine functions to move the car). If a machine is 'on' but not doing its job, it '작동' is fine but it doesn't '기능'.

Both are correct. '기능하다' is the verb form, while '기능을 하다' emphasizes the noun 'function.' In most cases, they are interchangeable, but '기능하다' is slightly more concise.

Yes, laws function as deterrents or as frameworks for society. This is a very common usage in legal and social science texts.

You can say '오작동하다' (for machines) or '기능 장애가 있다' (to have a functional disorder) or simply '제대로 기능하지 못하다'.

Not always, but very frequently. It can also be used with adverbs (정상적으로 기능하다) or just by itself if the context is clear.

It means 'functionality.' It's often used as an adjective-like noun for products, like '기능성 신발' (functional/orthopedic shoes).

Yes, it's perfect for software. 'This module functions to encrypt data' would be '이 모듈은 데이터를 암호화하는 기능을 합니다' or '암호화 모듈로서 기능합니다'.

In daily casual speech, no. In school, work, or media, yes, it is extremely common.

No, '기능하다' is already describing a state/action of the subject. You wouldn't say 'is functioned'.
