例文 メモとヒント 방출 30秒で
解説 방출 in your Level:
In very simple terms, '방출' (bang-chul) means 'to let something out' or 'to send something away.' Imagine a ball coming out of a box. In Korean, when heat comes out of a heater, we use this word. It's like the English word 'out.' You might not use it every day at this level, but you will see it in books when talking about the sun or fire. Just remember: Bang (release) + Chul (exit). Something is exiting its home.

At the A2 level, you can start using '방출' to describe simple physical actions. For example, 'The stove releases heat' (난로가 열을 방출해요). You might also see it in news headlines about sports. If a famous baseball player leaves his team because the team doesn't want him anymore, the news will say he was '방출' (released). It is a noun, but you can add '하다' to make it a verb: '방출하다.'

As a B1 learner, you should recognize '방출' in more formal contexts like science class or news reports. You will see it used with words like 'gas' (가스), 'energy' (에너지), and 'light' (빛). It is also used in economics when the government 'releases' items from storage to help people. For example, 'The government released rice to lower the price.' You should be able to distinguish between '방출' (general release/sports release) and '배출' (waste discharge).
At the B2 level, you should be comfortable using '방출' in academic and professional discussions. You will understand its passive form '방출되다' and how it is used in environmental contexts, such as 'CO2 emissions' (이산화탄소 방출). You should also understand the nuance in sports—that a 'released' player is different from a 'traded' player. A released player is often cut from the team, which is a specific professional situation. You can use this word to describe chemical reactions or electronic processes.

For C1 learners, '방출' is a precise technical term. You should understand its etymological roots and its usage in high-level physics (e.g., spontaneous emission of photons). You will also encounter it in complex socio-economic contexts, such as the strategic release of national oil reserves. You should be able to use it metaphorically or in highly specific collocations like '방출 명단' (waiver/release list) or '방사능 물질 방출' (release of radioactive materials). Your usage should reflect the distinction between 'emission' and 'expulsion.'

At the C2 level, you possess a nuanced understanding of '방출' across all domains. You can discuss the legal implications of a '방출' in a sports contract, the thermodynamic principles of '열 방출' (heat dissipation), and the environmental policy surrounding '탄소 방출권' (carbon emission rights). You can use the word in sophisticated sentence structures, utilizing it to describe anything from the quantum mechanics of electron emission to the macro-economic strategies of supply-side intervention. You understand its synonyms' subtle register differences perfectly.

例文 メモとヒント

방출 30秒で

  • 방출 means 'release' or 'emission.' It is most commonly used for energy (heat, light) or substances (gas, radiation) being sent out from a source.
  • In sports, it refers to a team releasing a player. This usually means the player is no longer on the team and is free to find another.
  • In economics, it refers to the government releasing stockpiled goods like rice or oil into the market to help stabilize prices for citizens.
  • It is a formal noun often paired with '하다' (to do) or '되다' (to be done) to function as a verb in various contexts.

The Korean word 방출 (Bang-chul) is a versatile noun that primarily translates to 'release,' 'emission,' or 'discharge.' Derived from the Hanja characters 放 (to release/let go) and 出 (to go out), it describes the physical or metaphorical act of something being sent out from a container, a source, or an organization. While it sounds technical, its application spans from high-level physics to the daily sports news cycle.

Scientific Context
In science, it refers to the emission of energy, particles, or substances. For instance, when a light bulb is turned on, it emits light (빛의 방출). Similarly, when radioactive materials decay, they release radiation (방사능 방출). It is a neutral term used to describe natural or mechanical processes where something is expelled outward.

태양은 엄청난 양의 에너지를 우주로 방출합니다. (The sun emits a massive amount of energy into space.)

Sports and Human Resources
In the world of professional sports, particularly baseball and soccer, 방출 refers to the 'release' of a player from a team's roster. This usually happens when a player is no longer needed or fails to meet performance standards. Unlike a 'transfer' (이적), which implies moving to another team for a fee, a release often means the player becomes a free agent or is simply cut from the squad.

Furthermore, the word is used in economics to describe the government releasing stockpiled goods (like rice or oil) into the market to stabilize prices. This action is called '비축 물자 방출.' Whether it is a gas escaping a pipe or a player leaving a team, the core concept remains: something that was inside or part of a whole is now being sent out.

Using 방출 correctly requires understanding its role as a noun and its common verbal form, 방출하다 (to release/emit) or 방출되다 (to be released/emitted). Depending on the subject, the choice between the active and passive voice is crucial for natural-sounding Korean.

Active Usage (방출하다)
Used when the source is the subject. For example, 'The factory releases smoke' would be '공장이 연기를 방출한다.' It highlights the action of the source.

그 구단은 부진한 외국인 선수를 방출하기로 결정했습니다. (The club decided to release the underperforming foreign player.)

Passive Usage (방출되다)
Used when focusing on the thing being released. 'Heat is released' would be '열이 방출된다.' This is very common in scientific reporting and news.

화학 반응 중에 많은 열이 방출되었습니다. (A lot of heat was released during the chemical reaction.)

In formal writing, you will often see it paired with particles like '-의' (of) to form compound nouns such as '이산화탄소의 방출' (the emission of carbon dioxide). In these cases, it functions as a formal technical term.

You are likely to encounter 방출 in three specific environments: the evening news, sports broadcasts, and science documentaries. Each context uses the word with a slightly different weight.

1. Sports News (The Most Common)
If you follow the KBO (Korean Baseball Organization) or K-League, you will hear this word every off-season. Commentators will discuss which players are on the '방출 명단' (release list). It is a dramatic word in this context, signaling the potential end of a career.

베테랑 투수가 팀에서 방출되었다는 소식에 팬들이 충격을 받았습니다. (Fans were shocked by the news that the veteran pitcher was released from the team.)

2. Environmental and Science Reports
When the news covers global warming, they talk about '온실가스 방출' (greenhouse gas emissions). In physics documentaries, you'll hear about '에너지 방출' (energy release) concerning stars or nuclear power.

후쿠시마 원전의 오염수 방출 문제는 국제적인 이슈입니다. (The issue of releasing contaminated water from the Fukushima nuclear plant is an international issue.)

While 방출 is straightforward, learners often confuse it with other words related to 'releasing' or 'sending out' such as 배출, 발산, or 발표.

방출 vs. 배출 (Bae-chul)
This is the most common confusion. '배출' is typically used for waste, exhaust, or the 'production' of talented individuals (e.g., 'The school produced/discharged many leaders'). '방출' is more about the physical emission of energy or the dismissal of a member. You '배출' trash, but a star '방출' light.
방출 vs. 발산 (Bal-san)
'발산' means to radiate or emanate, often used for abstract things like 'charm' (매력 발산) or 'energy' in a more expressive way. '방출' is more technical and literal.

Incorrect: 매력을 방출하다. (Technically possible but sounds like you are shooting charm out of a cannon.)
Correct: 매력을 발산하다.

To sound more like a native speaker, you should know which 'release' word fits each specific situation. Here is a comparison of synonyms for 방출.

배출 (Discharge/Exhaust)
Best for waste products, carbon emissions from cars, or sewage. It implies a 'cleaning out' process. Example: 자동차 배기가스 배출 (car exhaust emission).
퇴출 (Expulsion/Ousting)
Used when someone is kicked out of a market or a position permanently due to failure or scandal. It is stronger and more negative than '방출.' Example: 시장에서 퇴출당하다 (to be ousted from the market).
발산 (Radiation/Emanation)
Used for things that spread out in all directions, like scents, heat, or personality traits. Example: 향기 발산 (spreading of a scent).

Comparison: 가스 방출 (Sudden release of gas) vs. 가스 배출 (Planned discharge of waste gas).

If you are talking about releasing a prisoner, use '석방' (Seok-bang). If you are releasing a new product, use '출시' (Chul-si). Korean has very specific words for 'release' depending on the object!

How Formal Is It?

豆知識

The character 放 (방) is also used in '방송' (broadcasting), which literally means 'sending out a release' of signals/media.

発音ガイド

UK /paŋ.tɕʰul/
US /baŋ.tɕʰul/
In Korean, syllables usually have equal stress, but the second syllable '출' can sound slightly more emphatic due to the aspirated 'ㅊ'.
韻が合う語
수출 (Export) 매출 (Sales) 제출 (Submission) 노출 (Exposure) 탈출 (Escape) 추출 (Extraction) 호출 (Call) 산출 (Calculation/Output)
よくある間違い
  • Pronouncing '방' as 'bang' like in English (it should be more like 'bahng').
  • Failing to aspirate the 'ㅊ' in '출' (making it sound like 'jul').
  • Over-voicing the initial 'ㅂ' (it should be between 'b' and 'p').
  • Pronouncing the final 'ㄹ' as an English 'r' (it should be a light tap or 'l').
  • Confusing it with '반출' (taking something out of a building/country).

チャレンジ

Try to find three news articles today that use the word '방출'. One must be sports-related and one must be science/environment-related.

語源

The word is composed of two Hanja (Chinese characters): 放 (방) meaning 'to release, let go, or set free' and 出 (출) meaning 'to go out or exit.' Together, they literally mean 'to let something go out.'

元の意味： Originally used to describe the act of setting animals free or allowing people to leave a confined space.

Sino-Korean (Hanja-derived)

文化的な背景

Be careful when using '방출' about people in a non-sports context, as it sounds very cold and dehumanizing, like discarding an object.

In English, we use different words: 'emit' for science, 'release' for sports, and 'discharge' for waste. Korean uses '방출' for the first two, but '배출' for the third.

KBO League off-season '방출' news. Fukushima '방출' (contaminated water release) debates in Korean media. Scientific textbooks discussing '에너지 방출' (energy release).
