Explicação 전구 in your Level:

At the A1 level, you only need to know that '전구' (jeon-gu) means 'light bulb.' You might see it in pictures or point to it in a store. You should learn it alongside basic verbs like '있다' (to have/exist) and '없다' (to not have). For example, '전구가 있어요?' (Is there a light bulb?). At this stage, focusing on the physical object is enough. You don't need to worry about different types of bulbs yet. Just remember that it is a noun and usually ends a sentence with '이에요' or '예요.' For instance, '이것은 전구예요' (This is a light bulb). It's a very concrete noun, making it easy to memorize with a flashcard showing a picture of a shining bulb. You might also hear it when someone is talking about a room being dark. '방이 어두워요. 전구가 필요해요.' (The room is dark. I need a light bulb.) This simple usage is the foundation for everything else.

At the A2 level, you should be able to use '전구' in simple daily life scenarios. This includes knowing the verb '갈다' (to change/replace). A common A2 sentence would be '전구를 갈아야 해요' (I have to change the light bulb). You should also be familiar with basic adjectives to describe the bulb, such as '밝다' (bright) or '어둡다' (dark). You might encounter this word when talking about household chores or shopping. If you are in a supermarket, you should be able to ask where the bulbs are: '전구는 어디에 있어요?' You also start to learn about different colors, like '하얀색 전구' (white bulb) or '노란색 전구' (yellow bulb). This level is about practical application—using the word to solve a small problem at home or to buy a replacement. You can also start using the counter '개' (gae) properly, such as '전구 두 개 주세요' (Please give me two light bulbs).

By the B1 level, you can describe the state of a light bulb more specifically. Instead of just saying it's 'broken,' you use the natural expression '전구가 나갔어요' (the bulb went out). You can also discuss energy efficiency or the type of bulb, like 'LED 전구' or '백열전구.' You might explain a situation: '전구가 갑자기 나가서 너무 당황했어요' (I was so flustered because the bulb suddenly went out). At this level, you can also understand the metaphorical use of a light bulb in cartoons or stories to represent an idea. You might use '전구' in the context of interior design, discussing how a certain bulb changes the '분위기' (atmosphere) of a room. You are comfortable using different particles and conjunctions with the word, such as '전구를 갈았는데도 여전히 어두워요' (I changed the bulb, but it's still dark). This shows a deeper understanding of cause and effect in Korean.

At the B2 level, you can engage in more detailed discussions involving '전구.' This might include talking about the history of technology (e.g., Thomas Edison) or the environmental impact of different lighting choices. You can use terms like '수명' (lifespan), '소비 전력' (power consumption), and '환경 보호' (environmental protection). You might compare bulbs: 'LED 전구는 백열전구보다 수명이 훨씬 길고 에너지 효율이 높습니다' (LED bulbs have a much longer lifespan and higher energy efficiency than incandescent bulbs). You can also handle more complex administrative tasks, like reporting a maintenance issue in an apartment complex or office. You understand nuances like '주광색' (daylight) versus '전구색' (warm white) and can explain which one you prefer and why. Your vocabulary surrounding the word expands to include technical terms like '필라멘트' (filament) or '소켓' (socket).

At the C1 level, you can use '전구' in sophisticated metaphorical or academic contexts. You might discuss the '전구' as a symbol of the Second Industrial Revolution or use it in a literary sense to describe a flickering light representing hope or instability. You can read technical manuals or articles about semiconductor technology in LED bulbs without much difficulty. You understand the socio-economic impact of lighting on urban development. In discussions about innovation, you might use the light bulb as an analogy for '발상' (idea/conception). You can also navigate complex consumer disputes, such as discussing a warranty for a high-end smart bulb. You use advanced grammar structures effortlessly, such as '전구 하나가 세상을 바꿨다고 해도 과언이 아니다' (It is no exaggeration to say that a single light bulb changed the world). Your understanding is no longer just about the object, but its role in history and society.

At the C2 level, your mastery of '전구' is near-native. You can appreciate wordplay, puns, or deep cultural references involving light bulbs. You can discuss the physics of light emission (광학) or the chemical composition of gases inside specialized bulbs. You might write a professional review of lighting systems or a research paper on the transition from traditional lighting to smart-city LED infrastructure. You are familiar with rare or archaic terms related to lighting and can contrast '전구' with historical lighting methods like '호롱불' or '촛불' in a historical analysis. You can speak eloquently about the psychological effects of different light temperatures on human productivity. At this level, the word '전구' is a simple tool in a vast arsenal of language, used with perfect precision, whether in a casual joke or a high-level scientific debate. You can even understand and use industry-specific jargon related to bulb manufacturing and distribution.

전구 em 30 segundos

전구 (Jeon-gu) means light bulb in Korean, derived from 'electric' + 'ball'.
It is a common noun used for house maintenance and shopping for lighting.
Commonly paired with '갈다' (to change) or '나갔다' (went out/burnt out).
Distinguished from '등' (lamp fixture) and '형광등' (fluorescent tube).

The Korean word 전구 (Jeon-gu) refers specifically to an electric light bulb. Derived from Sino-Korean roots, it literally translates to an 'electric ball' or 'electric sphere.' In everyday life, this is the standard term used when you need to replace a burnt-out light in your ceiling, desk lamp, or refrigerator. Whether you are at a local convenience store (편의점) or a large hardware mart, this is the word you will use to find lighting supplies.

Everyday Utility: In a residential context, Koreans use '전구' to describe the physical object that produces light. It is distinct from '등' (lamp/light fixture) or '조명' (lighting/illumination). If the light stops working, you don't 'change the light'; you 'change the bulb' (전구를 갈다).

화장실 전구가 나갔어요. (The bathroom light bulb has gone out.)

Historically, '전구' mostly referred to incandescent bulbs (백열전구), which were common in Korean households until the early 2000s. However, with the rapid advancement of technology in South Korea, most people now use 'LED 전구.' Despite the change in technology, the base word remains the same. You might also hear it in metaphorical contexts, similar to English, where a light bulb appearing over someone's head signifies a sudden realization or a 'bright idea.'

Technical Nuance: In technical or industrial settings, '전구' is the specific component. If you are talking about the entire street light, you would say '가로등,' but if you are talking about the bulb inside that street light, you return to '전구.'

이 전구는 에너지를 절약해 줍니다. (This light bulb saves energy.)

Culturally, the 'light bulb' image is universally recognized in Korea. In Korean variety shows or webtoons, you will frequently see a light bulb graphic pop up next to a character's head when they solve a puzzle or have a clever thought. This visual shorthand is so pervasive that '전구' has become synonymous with 'idea generation' in creative brainstorming sessions.

Types of Bulbs: Koreans distinguish between '주광색' (daylight/cool white) and '전구색' (bulb color/warm yellow). If you want that cozy, yellowish light, you must ask for '전구색 전구.'

따뜻한 느낌을 위해 전구색을 선택하세요. (Choose the bulb-color (warm white) for a warm feeling.)

Using '전구' in a sentence requires understanding the verbs that typically accompany it. The most common verb is '갈다' (to change/replace) or '교체하다' (to replace - more formal). When a bulb stops working, Koreans say '전구가 나가다' (the light bulb went out) or '전구가 수명을 다하다' (the light bulb reached the end of its life). These collocations are essential for natural-sounding Korean.

Action Verbs: '끼우다' (to insert/screw in) and '빼다' (to take out/unscrew) are the physical actions. '사다' (to buy) and '찾다' (to look for) are common shopping verbs. '밝히다' (to light up) is used more poetically or technically.

새 전구를 소켓에 끼우세요. (Insert the new bulb into the socket.)

Grammatically, '전구' functions as a regular noun. It can be the subject of a sentence using particles '-가/이' or the object using '-를/을.' Since it is an inanimate object, it is counted using the counter '개' (gae). For example, '전구 세 개' (three light bulbs). In more formal or industrial contexts, you might see the counter '립' (rip) for small electronic components, but '개' is 99% of what you'll need.

Descriptive Usage: Adjectives often used include '수명이 긴' (long-lasting), '에너지 효율적인' (energy-efficient), and '눈이 편안한' (comfortable for the eyes).

이 전구는 수명이 아주 길어요. (This light bulb has a very long lifespan.)

In complex sentences, you might connect '전구' with reasons or conditions. '전구가 나가서 방이 캄캄해요' (Because the bulb went out, the room is pitch black). '전구를 갈면 다시 밝아질 거예요' (If you change the bulb, it will be bright again). Notice how the particle '-가' is used when the bulb is the thing doing the 'going out,' but '-를' is used when you are the one doing the 'changing.'

Common Mistakes: Learners often confuse '전구' (bulb) with '등' (light/lamp). If you say '등을 갈다,' it sounds like you are replacing the entire lamp fixture, not just the bulb.

스탠드 전구를 확인해 보세요. (Please check the desk lamp bulb.)

You will encounter the word '전구' in several distinct environments in Korea. The most common is the retail environment. In a 'Daiso' (다이소) or a 'Lotte Mart' (롯데마트), the signage for the electrical aisle will clearly display '전구' or '조명/전구.' If you are looking for a specific type, like a decorative bulb for a cafe-like atmosphere at home, you will search for '인테리어 전구' (interior bulb) or '에디슨 전구' (Edison bulb).

Retail & Shopping: Shopping apps like Coupang or Naver Shopping are filled with listings for 'LED 전구.' You will see phrases like '무료 배송' (free shipping) and '당일 발송' (same-day shipping) attached to these products.

요즘은 전구도 스마트폰으로 제어해요. (These days, even light bulbs are controlled by smartphones.)

In the workplace, particularly in office management or maintenance, '전구' is a frequent topic of conversation. If a light is flickering, an employee might report it to the facility manager (관리실) by saying, '사무실 전구가 깜빡거려요' (The office bulb is flickering). In these professional contexts, the word is used purely functionally. Maintenance logs will record '전구 교체' (bulb replacement) as a routine task.

Media & Pop Culture: In educational programs or science documentaries (like those on EBS), '전구' is used to explain circuits (회로) and electricity. You might see a diagram of a '꼬마전구' (miniature bulb/grain of wheat bulb) used in primary school science experiments.

에디슨은 전구를 발명했습니다. (Edison invented the light bulb.)

Another surprising place you'll hear it is in interior design shows (like '인테리어 가이드'). Experts will discuss '전구의 색온도' (color temperature of the bulb) to change the mood of a room. They might suggest '전구색' (warm yellow) for the bedroom and '주광색' (bright white) for the study. This shows that '전구' isn't just a utility but a design element in modern Korean life.

Public Spaces: In subway stations or public restrooms, if a light is out, you'll see a notice: '전구 교체 중' (Bulb replacement in progress). It's a very common sight in busy urban environments.

축제 때 예쁜 전구들이 많았어요. (There were many pretty light bulbs at the festival.)

One of the most frequent mistakes English speakers make is using the word '불' (bul/fire) when they specifically mean the physical bulb. While '불을 켜다' means 'to turn on the light,' '불' refers to the light/illumination itself, not the glass object. If you say '불을 갈다' (to change the fire/light), it's technically understandable in context but sounds very unnatural. You must use '전구를 갈다.'

Confusion with '등' (Deung): Another pitfall is using '등' (lamp/light) interchangeably with '전구.' '등' is the fixture (the thing attached to the ceiling), while '전구' is the bulb inside. If you go to a shop and ask for a '등,' they might show you a whole new chandelier or a ceiling light unit instead of just a replacement bulb.

틀린 표현: 불을 갈아야 해요. (Incorrect: I need to change the fire.)
옳은 표현: 전구를 갈아야 해요. (Correct: I need to change the bulb.)

A subtle mistake involves the counter. English speakers might say '전구 하나' (one light bulb), which is okay, but '전구 한 개' is the more standard way to count them. Using the wrong counter (like '한 명' for people or '한 마리' for animals) is a classic beginner mistake. Stick to '개' for light bulbs.

Verbal Mismatch: Using '고장나다' (to be broken) for a light bulb is common but slightly off. While a bulb is technically broken when it doesn't work, Koreans almost always use '나갔다' (went out) or '수명이 다했다' (life ended). '전구가 고장났어요' sounds like the internal mechanism of a complex machine failed, rather than a simple filament burning out.

어색한 표현: 전구가 고장났어요. (Awkward: The bulb is broken.)
자연스러운 표현: 전구가 나갔어요. (Natural: The bulb went out.)

Lastly, learners often forget that '전구' refers to the *electric* bulb. If you are talking about an old-fashioned oil lamp or a candle, '전구' is never used. For those, you would use '등불' (lamp light) or '촛불' (candle light). '전구' is strictly for the era of electricity. This is a common conceptual mistake when translating 'light' in historical contexts.

Spelling Errors: Avoid writing '전규' or '정구.' '전구' (電球) is the only correct spelling. '정구' (Jeong-gu) actually means 'soft tennis'!

While '전구' is the most common term for a light bulb, there are several related words that you should know to expand your vocabulary and speak more precisely depending on the situation. Understanding these nuances will help you distinguish between the source of light and the fixture itself.

전구 (Jeon-gu) vs. 형광등 (Hyeong-gwang-deung): '전구' usually refers to the round, bulbous type (incandescent or LED). '형광등' refers to the long, fluorescent tubes commonly found in offices and older Korean apartments. If you need to replace a tube, you ask for a '형광등,' not a '전구.'

거실은 형광등이고, 침실은 전구예요. (The living room has fluorescent lights, and the bedroom has bulbs.)

Then there is '조명' (Jo-myeong). This is a broad, academic, or professional term for 'lighting' or 'illumination.' You might hear this in a photography studio or when discussing the 'lighting design' of a building. It's a more formal word than '전구.' If you are talking about the atmosphere, you say '조명이 좋다' (the lighting is good).

전구 (Jeon-gu) vs. 전등 (Jeon-deung): '전등' (Electric light) is a bit more general than '전구.' It refers to the whole electric light unit. '전등을 켜다' (turn on the light) is very common. '전구' is the specific component you screw in.

전등 스위치를 누르세요. (Press the light switch.)

In modern contexts, you will almost always see 'LED' prefixed to these words. 'LED 전구' has largely replaced '백열전구' (incandescent bulb) in stores. If you want a specific shape, you might use '삼파장 전구' (three-wavelength bulb/CFL) or '볼전구' (ball bulb). Knowing these variations will make you sound like an expert when shopping for home supplies.

Summary Table: - 전구: The bulb itself.
- 형광등: Fluorescent tube.
- 조명: Lighting (general/artistic).
- 전등: Electric light fixture.
- 램프: Lamp/Specialty bulb.

Erros comuns

Using '불' to mean the bulb. → 전구
While '불' means light, you can't 'change a light' in the physical sense of a bulb. You must say '전구를 갈다'.
Saying '전구가 죽었어요'. → 전구가 나갔어요
In English, we say 'the bulb died,' but in Korean, you say 'it went out' (나갔어요).
Confusing '전구' with '전국'. → 전구
The 'k' sound at the end of '전국' changes the meaning to 'nationwide.' Be careful with the final sound.
Using '고장나다' for a burnt-out bulb. → 수명이 다하다 / 나가다
'고장나다' is for broken machines. For a simple bulb, '나가다' is much more natural.
Calling a fluorescent tube '전구'. → 형광등
'전구' is specifically for bulb-shaped lights. Tubes have their own name: '형광등'.

Dicas

Learn the Root

Remembering that '전' (Jeon) means electricity will help you learn hundreds of other words like '전기' (electricity), '전화' (telephone), and '전철' (subway).

Subject vs Object

Use '전구가' when the bulb does something (like going out) and '전구를' when you do something to the bulb (like buying or changing it).

Warm vs Cool

In Korea, offices usually use '주광색' (cool white), while homes often mix '주광색' and '전구색' (warm). Knowing these terms helps when shopping.

Clear Vowels

Make sure to distinguish 'eo' (ㅓ) in 'Jeon' from 'o' (ㅗ). If you say 'Jon-gu,' it might sound like a name rather than a light bulb.

Check the Socket

When buying a '전구' in Korea, look for the 'E26' or 'E14' size on the box. These are the standard socket sizes (소켓 사이즈).

Heat Warning

Koreans often warn '전구 뜨거워요' (The bulb is hot). Incandescent bulbs get very hot, so always turn off the switch before touching them.

Idea Bulb

Use '머릿속에 전구가 켜지다' in your writing to sound more like a native when describing a 'Eureka' moment.

Interior Design

If you want to describe a 'vibe,' use '조명발' (lighting effect). A good '전구' provides good '조명발'!

Flashcard Tip

Draw a light bulb on one side and write '전구' on the other. Add '갈다' and '나가다' to the corners for extra context.

Mart Announcements

Listen for '할인' (discount) and '전구' together in supermarkets. Bulbs are often sold in '1+1' deals.

Memorize

Mnemônico

Think of a 'John' (Jeon) who is holding a 'Gooey' (Gu) light bulb. John + Goo = Jeon-gu.

Associação visual

Visualize a round ball (Gu) with lightning bolts (Jeon) inside it. It's an electric ball!

Word Web

전기 (Electricity) 구체 (Sphere) 빛 (Light) 에디슨 (Edison) 유리 (Glass) 소켓 (Socket) 와트 (Watt) 밝다 (Bright)

Desafio

Go to a local store or look at the lamps in your house. Every time you see a bulb, point at it and say '전구' out loud three times.

Origem da palavra

The word '전구' is a Sino-Korean word. It is composed of two Hanja characters: 電 (전) and 球 (구).

Significado original: 電 (Jeon) means 'electricity' or 'lightning,' and 球 (Gu) means 'ball' or 'sphere.' Together, they describe an 'electric sphere.'

Sino-Korean (Hanja-based Korean vocabulary).

Contexto cultural

There are no major sensitivities, but be aware that '전구' is a technical term; in poetic contexts, '불빛' (light) is often preferred.

In English, we say 'the light bulb went off' for an idea; Koreans say '머릿속에 전구가 켜졌다' (a light bulb turned on in the head). The concept is identical.

Thomas Edison (에디슨) is universally taught in Korea as the father of the 전구. The 'Light Bulb' emoji 💡 is used in KakaoTalk just as it is in WhatsApp to signify an idea. Many Korean 'Escape Rooms' use flickering 전구 to create a horror atmosphere.

Perguntas frequentes

10 perguntas

You should ask for '전구색 전구' (Jeon-gu-saek Jeon-gu). '전구색' literally means 'bulb color' and refers to that warm, yellowish glow. For example, '전구색 전구 있어요?' (Do you have warm-colored bulbs?).

The most natural verb is '나가다' (to go out). You say '전구가 나갔어요.' Avoid using '고장나다' (to be broken) as it sounds a bit too mechanical for a simple bulb. '나갔어요' is what every Korean uses at home.

Yes, it is. Even though LEDs aren't technically 'bulbs' in the old sense, they are still called 'LED 전구' because they serve the same purpose and often have the same shape. It's the standard term for the light-emitting component.

Use '개' (gae), which is the general counter for items. One bulb is '전구 한 개,' two bulbs are '전구 두 개,' and so on. Do not use '명' (people) or '장' (flat objects).

You use the verb '빼다' (to take out). So, '전구를 빼다' means to unscrew or remove the bulb. If you want to say 'screw it in,' use '끼우다' (to insert/fit in). For example, '전구를 조심해서 빼세요' (Carefully take out the bulb).

'꼬마' means 'little kid' or 'tiny.' So '꼬마전구' refers to those tiny little bulbs used in science experiments, holiday decorations, or small flashlights. It's a very cute and common word.

Not exactly. A flashlight is '손전등' (hand electric light). However, the tiny bulb inside the flashlight can be called a '전구' or '꼬마전구.' You wouldn't call the whole flashlight a '전구'.

Yes. '전구' is the bulb itself. '전등' is a more general term for 'electric light' and can refer to the whole lamp or the light coming from it. '전등을 켜다' is common, but '전구를 갈다' is specific to the object.

Use the verb '깜빡거리다.' You say '전구가 깜빡거려요.' This is very useful for reporting issues to a landlord or maintenance office. For example, '주방 전구가 깜빡거려요' (The kitchen bulb is flickering).

It refers to 'Edison Bulbs,' which are vintage-style bulbs with visible filaments. They are very popular in Korean cafes and interior design right now. You'll see them listed as '에디슨 전구' in shops.
