解説 곱해지다 in your Level:

At the A1 level, you should understand '곱해지다' as a basic math word. Think of it as the passive version of 'multiply'. In Korean, we often use the word '곱하기' (multiplication) in early lessons. '곱해지다' is what happens to the numbers. For example, if you have 2 and you multiply it by 3, you can say '2에 3이 곱해졌어요' (2 was multiplied by 3). It is important to notice the '-어지다' part at the end, which means something is happening to the subject. Even if you don't use it in complex sentences yet, recognizing it in a math context or when someone talks about things increasing quickly is a great start. You might see this in simple workbooks or hear it when a teacher explains a basic calculation. Focus on the fact that it means 'to be multiplied' and is used when we talk about the result of math.

At the A2 level, you can start using '곱해지다' in simple sentences about growth and change. You should be familiar with the grammar pattern '-어지다', which turns active verbs into passive ones or describes a change in state. When you use '곱해지다', you are describing a situation where something increases not just by adding, but by a factor. For example, '인구가 곱해지듯 늘어났어요' (The population increased as if it were multiplied). You can also use it to describe simple logic in games or basic finance, like '점수가 곱해집니다' (The score is multiplied). Practice connecting it with the particle '-면' to say things like '이 숫자가 곱해지면...' (If this number is multiplied...). This level is about moving from just recognizing the word to using it in structured, predictable contexts.

At the B1 level, you should be comfortable using '곱해지다' in both literal mathematical contexts and metaphorical ones. You can use it to describe more complex scenarios, such as the compounding effect of habits or the synergy of teamwork. At this stage, you should pay attention to the particles used: 'A가 B에 곱해지다'. You can also use the past tense '곱해졌다' to describe results in reports or essays. For instance, '기술과 자본이 만나 가치가 곱해졌습니다' (Technology and capital met, and the value was multiplied). You should also be able to distinguish it from '더해지다' (to be added) and '배가되다' (to be doubled), choosing '곱해지다' when you specifically want to emphasize a factor-based or exponential increase. It's a useful word for explaining logic or describing rapid social changes.

At the B2 level, '곱해지다' becomes a tool for sophisticated description. You will encounter it in news articles, documentaries, and academic texts. You should understand how it functions in complex sentence structures, such as '곱해짐에 따라' (as it is multiplied) or '곱해진 결과로' (as a result of being multiplied). At this level, you can use it to describe abstract concepts like '불안감이 곱해지다' (anxiety being compounded) or '영향력이 곱해지다' (influence being multiplied). You should also understand the nuance it brings to a sentence compared to simpler verbs like '늘어나다'. It implies a systematic or structural reason for the increase. In discussions about the economy or science, '곱해지다' is essential for describing non-linear growth patterns and the interaction of different variables.

At the C1 level, you should have a nuanced command of '곱해지다' in formal and professional registers. You can use it in high-level academic writing or business strategy presentations to describe complex interactions. You should be able to use it fluently in structures like 'A와 B의 상호작용이 곱해지면서...' (As the interaction between A and B is multiplied...). You will also recognize it in literature where it might be used to describe the layering of history or the compounding of cultural influences. At this level, you should also be aware of its rare synonyms or related Hanja-based terms, though '곱해지다' remains the standard. Your usage should reflect an understanding of the word's ability to describe not just quantity, but the qualitative transformation that occurs when factors multiply each other.

At the C2 level, you use '곱해지다' with the precision of a native speaker, often using it in philosophical or highly technical discourse. You understand the subtle poetic weight it can carry in a literary context, describing the 'multiplied echoes' of the past or the 'multiplied dimensions' of a complex argument. You can use it to explain intricate mathematical proofs or economic theories like the multiplier effect with perfect grammatical accuracy. You are also sensitive to the rhythmic qualities of the word in speech and writing, using it to create emphasis or to draw a clear distinction between simple addition and complex multiplication of ideas. At this level, '곱해지다' is not just a vocabulary word but a conceptual tool for expressing the highest levels of systemic complexity.

곱해지다 30秒で

A passive verb meaning 'to be multiplied' in mathematical contexts.
Commonly used to describe exponential growth or compounding effects in finance and science.
Metaphorically describes feelings or social phenomena that intensify rapidly.
Requires the passive grammar structure '-어지다' and typically uses the particle '-에' for the multiplier.

The Korean verb 곱해지다 is a passive verb that translates to 'to be multiplied' in English. It is a compound verb formed by the root '곱' (multiplication/layer), the verb '하다' (to do), and the passive auxiliary verb '-어지다' (to become/be done). In its most literal sense, it is used in mathematics to describe the process where one number is increased by a factor of another. However, its usage extends far beyond the classroom, finding its way into economics, science, and even emotional descriptions where effects or feelings are compounded or amplified through some external influence.

Mathematical Context: In arithmetic, when you say 'A is multiplied by B', the Korean equivalent focuses on the number being acted upon. For example, '2가 3에 곱해지다' means '2 is multiplied by 3'. This passive construction is standard in textbooks and formal explanations of mathematical proofs.
Metaphorical Expansion: Beyond numbers, the word is used to describe the exponential growth of abstract concepts. If a problem is neglected, its difficulty might be described as '곱해지다', suggesting that it isn't just adding up, but multiplying in complexity. Similarly, joy shared with friends is often poetically described as being multiplied.

노력이 행운과 만나면 성공의 가능성이 곱해집니다.

Translation: When effort meets luck, the possibility of success is multiplied.

In daily life, you might hear this word when discussing financial interest, population growth, or the spreading of rumors. It carries a nuance of inevitable or systematic increase. For instance, in a scientific experiment, if a chemical reaction is catalyzed, the rate of reaction might be described as '곱해지는 속도' (the rate being multiplied). Understanding this word requires recognizing the '-어지다' pattern, which is a cornerstone of Korean passive voice and state-change expressions. It allows speakers to describe phenomena where the agent (the person doing the multiplying) is either unknown, unimportant, or the focus is entirely on the transformative outcome.

기쁨은 나누면 배가 되고, 슬픔은 나누면 곱해지지 않습니다.

Register and Tone: The word is neutral to formal. While it appears in elementary math books, its passive nature makes it sound slightly more sophisticated than the simple active '곱하다'. It is frequently used in news broadcasts regarding inflation or economic growth rates.

Using 곱해지다 correctly involves understanding its role as a passive verb. In Korean, passive verbs often require specific particles that differ from their active counterparts. When you multiply two numbers, the number that is being acted upon typically takes the subject marker '-이/가', and the number it is multiplied by takes the particle '-에' or '-와/과'. This structure highlights the relationship between the two values in a resulting state.

Structure 1: Mathematical Equations: [Number A]이/가 [Number B]에 곱해지다. (A is multiplied by B). This is the most common way to describe a step in a math problem.

이 숫자에 10이 곱해지면 소수점이 오른쪽으로 한 칸 이동합니다.

If 10 is multiplied to this number, the decimal point moves one space to the right.

Structure 2: Abstract Growth: [Abstract Noun]이/가 곱해지다. Here, the word describes an intensification. For example, '시너지 효과가 곱해지다' (Synergy effects are multiplied/compounded).

두 팀의 기술력이 곱해져서 혁신적인 제품이 탄생했습니다.

The technical skills of the two teams were multiplied (combined with compounding effect), leading to the birth of an innovative product.

When using this verb in conversation, it's important to conjugate it based on the tense and politeness level. In formal settings like a business presentation or a lecture, you would use '곱해집니다' or '곱해졌습니다'. In casual conversation, '곱해져' or '곱해졌어' are common. Because it is a process-oriented verb, it is frequently found in conditional forms like '-면' (if/when) or causal forms like '-어서/아서' (because/so).

잘못된 정보가 인터넷을 통해 곱해지듯 퍼져 나갔습니다.

The wrong information spread as if it were being multiplied through the internet.

Common Ending Patterns: 곱해지고 있다 (is being multiplied), 곱해질 것이다 (will be multiplied), 곱해져야 한다 (must be multiplied).

In technical writing, you might see the noun form '곱해짐' used in lists or summaries. For English speakers, the hardest part is often remembering that '곱해지다' is one word, whereas in English, 'to be multiplied' is three. The passive meaning is baked into the Korean verb ending, making it a concise way to express complex mathematical or systemic interactions.

You will encounter 곱해지다 in several distinct real-world environments. While it might seem like a niche academic term, its application in modern Korean society is surprisingly broad, especially in media and professional discourse.

1. Educational Settings: From elementary school math classes to university-level engineering lectures, this is the standard term. Teachers will say, '여기에 이 상수가 곱해지면...' (When this constant is multiplied here...). It is foundational for anyone studying STEM fields in Korean.

수학 시간: '가로와 세로가 곱해져서 넓이가 계산됩니다.'

Math Class: 'The width and height are multiplied to calculate the area.'

2. Economic News and Finance: Financial analysts use this word to describe compounding interest or the 'multiplier effect' (승수 효과) in the economy. When a government invests money, and that money leads to even more economic activity, they describe the initial investment as being multiplied across the market.

경제 뉴스: '금리 인상이 시장의 불안감에 곱해져 주가가 폭락했습니다.'

Economic News: 'The interest rate hike was multiplied by market anxiety, causing stock prices to plunge.'

3. Scientific Research: In biology or chemistry, researchers use '곱해지다' to describe cell division or the acceleration of a reaction. It implies a natural, often rapid, progression of growth.

In literature and songwriting, '곱해지다' is used to describe the overwhelming nature of feelings. A protagonist might say their longing for someone is 'multiplied' every day they are apart. This poetic usage elevates the word from a dry mathematical term to a vivid descriptor of emotional intensity. If you are watching a K-drama and a character is describing their growing ambition or their deepening love in a very deliberate, intense way, listen for this verb. It signals that the growth is not just steady, but explosive.

드라마 대사: '너와 함께하는 매 순간, 나의 행복이 곱해지는 기분이야.'

Drama line: 'Every moment I spend with you, it feels like my happiness is being multiplied.'

Even for advanced learners, using passive forms like 곱해지다 can be tricky. The most common errors usually involve particle choice, confusion with the active form, or mixing it up with similar-sounding mathematical operations.

Mistake 1: Confusing Passive and Active: Learners often use the active '곱하다' when they should use the passive '곱해지다'. Remember: '곱하다' needs a person or agent doing the math (I multiply the numbers). '곱해지다' is for when the focus is on the numbers themselves (The numbers are multiplied).

Incorrect: 숫자가 곱했어요. (The number multiplied - sounds like the number is a person doing math).
Correct: 숫자가 곱해졌어요. (The number was multiplied).

Mistake 2: Wrong Particles: Using the object marker '-을/를' with a passive verb is a classic error. Passive verbs generally do not take objects. Instead, use '-이/가' for the subject.

Incorrect: 결과를 곱해졌습니다.
Correct: 결과가 곱해졌습니다.

Another subtle mistake involves the use of '-에' versus '-를'. When saying 'multiply A by B', in the active voice it is 'A에 B를 곱하다'. In the passive, it becomes 'A에 B가 곱해지다'. Switching these can lead to confusion about which number is the base and which is the factor. Finally, avoid using '곱해지다' for physical things that are simply increasing in quantity but not by a factor; for that, '늘어나다' (to increase) is more natural. '곱해지다' always implies a mathematical-like relationship or a compounding effect.

Mistake 3: Over-complicating Simple Math: In very simple daily contexts, like doubling a recipe, Koreans might just say '두 배로 하다' (make it double) rather than '곱해지다'. Using '곱해지다' in a kitchen might sound overly scientific or robotic.

To truly master 곱해지다, it's helpful to compare it with other verbs that describe increase, addition, or intensification. Korean has a rich vocabulary for these concepts, each with its own specific nuance and register.

더해지다 (To be added): This is the passive of '더하다' (to add). It suggests a linear increase (1+1). While '곱해지다' suggests a multiplication (2x2), '더해지다' is more common for adding qualities, like '맛이 더해지다' (flavor is added/enhanced).
배가되다 (To be doubled/multiplied): Often used synonymously with '곱해지다' in metaphorical contexts. '배가되다' (倍加--) literally means to double, but it is frequently used to mean 'greatly increase'. It sounds slightly more formal and idiomatic than '곱해지다'.

기쁨이 배가되다 vs. 기쁨이 곱해지다

'배가되다' is a very common set phrase for joy, whereas '곱해지다' sounds more like a conscious description of the process.

증폭되다 (To be amplified): Used for sounds, signals, or emotions like tension and conflict. While '곱해지다' implies a factor-based growth, '증폭되다' implies an increase in volume or intensity.
늘어나다 (To increase/stretch): The most general term for increase in quantity, length, or amount. It is the safest choice if you aren't sure if multiplication is specifically involved.

In technical documentation, you might also see '승산되다' (to be multiplied), but this is extremely rare and mostly found in specialized mathematical texts or older literature. For modern learners, focusing on the distinction between '더해지다' and '곱해지다' is the most productive path to natural-sounding Korean.

よくある間違い

숫자를 곱해졌어요. → 숫자가 곱해졌어요.
Passive verbs like '곱해지다' take the subject marker '-이/가', not the object marker '-을/를'.
내가 숫자를 곱해졌어요. → 내가 숫자를 곱했어요.
If the subject is 'I' (the person doing the action), use the active verb '곱하다'.
기쁨이 더해지다 (when meaning exponential growth) → 기쁨이 곱해지다
'더해지다' implies simple addition; '곱해지다' implies a much stronger, compounding effect.
2와 3을 곱해지면... → 2에 3이 곱해지면...
The standard particle for the base number is '-에' and the multiplier is '-이/가'.
돈이 곱해졌어요 (for simple earning) → 돈이 늘어났어요
Unless the money grew by a specific factor (like interest), '늘어나다' is more natural for general increase.
