解析 퇴적물 in your Level:

At the A1 level, '퇴적물' (sediment) is a bit advanced, but you can understand it as 'dirty things at the bottom of water.' Imagine you put sand in a glass of water. After some time, the sand goes to the bottom. That sand is '퇴적물.' Even though you might not use this word every day, it helps to know it when you see pictures of rivers or the ocean in a book. You can think of it as 'earth stuff that stays at the bottom.' In simple Korean, you can think: '강 밑에 있는 흙' (Soil at the bottom of the river). The word is formal, so you will see it in books more than hearing it from friends. Just remember: water + time + dirt at the bottom = 퇴적물.

At the A2 level, you can start to connect '퇴적물' with nature and the environment. It's a noun used to describe things like mud, sand, and small stones that settle in water. You might see this word in a simple news headline about a river being dirty or in a basic science comic. When you go to the beach and see where the river meets the sea, the ground there is made of '퇴적물.' You should learn to pair it with the verb '쌓이다' (to be piled up). For example: '강에 퇴적물이 쌓여요' (Sediment piles up in the river). It's a good word to know if you are interested in talking about the Earth or the environment in a slightly more 'grown-up' way.

At the B1 level, you are expected to understand '퇴적물' in its primary geological and environmental contexts. This is the level where you should be able to distinguish it from '찌꺼기' (residue) or '앙금' (dregs). You will encounter this word in news reports about water quality, documentaries about the Earth's history, and geography lessons. You should understand that '퇴적물' is the result of '퇴적' (sedimentation/accumulation). At this stage, you can use it in sentences like '퇴적물을 분석하면 과거를 알 수 있습니다' (If you analyze sediment, you can know the past). You should also be familiar with compound nouns like '해양 퇴적물' (marine sediment) and '퇴적물 오염' (sediment pollution).

At the B2 level, you should be comfortable using '퇴적물' in academic or professional discussions. You understand the Hanja roots (堆積物) and how they contribute to the meaning of 'accumulated matter.' You can describe complex processes like how '퇴적물' forms '퇴적암' (sedimentary rock) over millions of years. You are also aware of the environmental implications of sediment buildup in dams and how it affects ecosystems. Your vocabulary should include related terms like '유입' (inflow), '채취' (collection/sampling), and '분포' (distribution). You can read a newspaper article about environmental policy and understand the nuances of how sediment management is discussed in a political or scientific framework.

퇴적물 30秒了解

퇴적물 means sediment or deposits that settle at the bottom of liquids, especially in nature.
It is a formal, Sino-Korean word used in geology, environmental science, and news reports.
Commonly paired with the verb 쌓이다 (to be piled up) to describe accumulation.
Distinguish it from daily words like 찌꺼기 (residue) or chemical terms like 침전물 (precipitate).

The Korean word 퇴적물 (toe-jeok-mul) is a technical yet common noun that translates primarily to 'sediment' or 'deposits.' In the most literal sense, it refers to any matter that settles to the bottom of a liquid, such as the sand and mud at the bottom of a river or the fine particles at the base of a wine bottle. However, its most frequent and significant application is within the fields of geology, environmental science, and geography. When geologists speak of the Earth's history, they are often reading the layers of 퇴적물 that have accumulated over millions of years to form sedimentary rocks. This word is composed of three Hanja characters: 堆 (퇴 - to pile up), 積 (적 - to accumulate), and 物 (물 - thing/matter). Together, they perfectly describe 'things that have been piled up and accumulated.'

Geological Context: In a scientific setting, 퇴적물 refers to the naturally occurring material that is broken down by processes of weathering and erosion, and is subsequently transported by the action of wind, water, or ice. This includes everything from massive boulders moved by glaciers to microscopic clay particles carried by the wind. When these particles lose their kinetic energy and settle, they become part of the geological record.
Environmental Science: Environmentalists often monitor 퇴적물 in rivers and oceans to check for pollutants. Because many heavy metals and toxins bind to fine particles, the sediment at the bottom of a lake can act as a historical record of local industrial activity. If a news report mentions 'riverbed contamination,' they will almost certainly use the word 퇴적물.
Everyday Analogies: While less common in casual conversation than words like '찌꺼기' (residue/dregs), you might hear 퇴적물 used to describe the buildup in a water tank or a pipe system that hasn't been cleaned in years. It carries a more formal, descriptive tone than its synonyms.

강 하구에는 오랜 세월 동안 쌓인 퇴적물이 삼각주를 형성합니다.
— At the river mouth, sediment accumulated over a long period forms a delta.

지질학자들은 해저 퇴적물을 분석하여 과거의 기후를 연구합니다.
Geologists analyze seafloor sediment to study past climates.

Understanding 퇴적물 is essential for anyone interested in Korean natural sciences or environmental news. It describes the physical foundation of our landscape. When you see a layered cliff side or a muddy riverbank, you are looking at the result of 퇴적 (accumulation). The word is versatile, appearing in academic papers, news broadcasts about flooding, and even in discussions about urban infrastructure maintenance. By learning this word, you gain a tool to describe the slow, powerful processes of nature that shape the world beneath our feet.

Using 퇴적물 correctly requires an understanding of its typical verb pairings and grammatical structures. As a noun, it most often serves as the subject or object of sentences involving accumulation, analysis, or removal. Because it is a Sino-Korean word (Hanja-based), it sounds relatively formal and is frequently used with the subject marker -이/가 or the object marker -을/를. The most common verb it pairs with is 쌓이다 (to be piled up/accumulated), which is the passive form of 쌓다 (to pile up).

The 'Accumulation' Pattern: The most natural way to describe sediment is to say it is 'piling up.' The phrase '퇴적물이 쌓이다' is a staple in geography textbooks. For example: '강 바닥에 퇴적물이 두껍게 쌓였습니다' (Sediment has piled up thickly on the riverbed). This pattern emphasizes the natural, passive process of settling.
The 'Scientific Action' Pattern: When humans interact with sediment, they usually 분석하다 (analyze), 채취하다 (collect/sample), or 제거하다 (remove). For instance: '연구팀은 호수에서 퇴적물을 채취했습니다' (The research team collected sediment from the lake). This shows the word in a more active, investigative context.

오염된 퇴적물을 제거하는 작업이 진행 중입니다.
— Work to remove contaminated sediment is underway.

이곳의 퇴적물은 주로 모래와 점토로 구성되어 있습니다.
— The sediment here consists mainly of sand and clay.

In complex sentences, 퇴적물 often appears in the possessive form 퇴적물의 or as part of a compound noun like 퇴적물 오염 (sediment pollution) or 해양 퇴적물 (marine sediment). When writing or speaking, remember that since it's a noun of 'stuff,' it is treated as an uncountable mass in English, but in Korean, you simply use the noun as is. You don't need a counter unless you are talking about specific 'samples' (점/개). Whether you are describing the silt in a dam or the layers of a canyon, 퇴적물 provides the precise vocabulary needed for clear, professional communication.

While 퇴적물 might seem like a word reserved for dusty textbooks, it actually appears in several common real-world scenarios in Korea. Understanding where you’ll encounter it helps bridge the gap between 'classroom Korean' and 'real-world Korean.'

The Evening News and Weather Reports: In Korea, heavy monsoon rains (장마) often lead to flooding and landslides. News anchors frequently report on how 퇴적물 has blocked drainage systems or changed the course of rivers. You might hear: '폭우로 인해 엄청난 양의 퇴적물이 유입되었습니다' (A massive amount of sediment has flowed in due to the heavy rain). It’s a key term for disaster reporting.
Documentaries and Educational Content: Korea has a rich variety of nature documentaries (like those on EBS or KBS). When these shows visit the 'Mudflats' (갯벌) of the West Coast, a UNESCO World Heritage site, the narrator will inevitably describe the rich organic 퇴적물 that supports the diverse ecosystem. If you are a student in Korea, this word is non-negotiable for middle and high school Earth Science classes.
Environmental Activism and Policy: Discussions about the 'Four Major Rivers Project' (4대강 사업) often center on 퇴적물. Activists and government officials debate how the buildup of sediment affects water quality and fish populations. If you read a newspaper editorial about the environment, look for this word.

뉴스: "댐 바닥에 쌓인 퇴적물 때문에 수질 오염이 우려됩니다."
— News: "There are concerns about water pollution due to sediment piled up at the bottom of the dam."

다큐멘터리: "이 암석은 수백만 년 전의 퇴적물이 굳어져 만들어졌습니다."
— Documentary: "This rock was formed by the hardening of sediment from millions of years ago."

In summary, 퇴적물 is the word of choice when the conversation turns to the Earth's physical processes, environmental health, or natural history. It’s a word that signals a level of sophistication and scientific awareness in your Korean vocabulary. While you won't use it to describe the crumbs on your dinner plate, you will hear it every time the natural world is analyzed or reported on.

Learning a technical term like 퇴적물 often comes with the challenge of distinguishing it from similar-sounding or similar-meaning words. Here are the most common pitfalls learners encounter.

Confusing '퇴적물' with '침전물': This is the number one mistake. 침전물 (chim-jeon-mul) refers to a precipitate—something that falls out of a liquid solution, often due to a chemical reaction. 퇴적물, on the other hand, is usually used for physical particles like sand or mud that settle due to gravity or a loss of water flow. If you're in a chemistry lab, use 침전물. If you're looking at a riverbed, use 퇴적물.
Using it for 'Kitchen Dregs': If you see coffee grounds at the bottom of your cup, calling them 퇴적물 would sound incredibly strange and overly scientific. In daily life, Koreans use 찌꺼기 (jji-kkeo-gi) for residue or dregs. Using 퇴적물 for coffee would be like an English speaker saying 'I have geological deposits in my espresso.'
Incorrect Verb Pairing: Learners sometimes use the verb 만들다 (to make) when they mean 'to form.' While sediment 'makes' a layer, the more natural geological term is 형성하다 (hyeong-seong-ha-da). Say '퇴적물이 지층을 형성했다' (Sediment formed a stratum) rather than '퇴적물이 지층을 만들었다.'

❌ 커피 퇴적물 (Coffee sediment - Too scientific)
✅ 커피 찌꺼기 (Coffee grounds/residue - Natural)

❌ 화학 반응으로 생긴 퇴적물 (Sediment from chemical reaction)
✅ 화학 반응으로 생긴 침전물 (Precipitate from chemical reaction)

By keeping these distinctions in mind, you'll avoid sounding like a 'science robot' in the kitchen or a 'casual tourist' in a geology lab. Precision is key with Sino-Korean vocabulary!

To truly master 퇴적물, you need to know its neighbors. Korean has several words for 'stuff left behind,' and choosing the right one depends entirely on the context and the 'vibe' of the situation.

침전물 (Precipitate / Settled Matter): As mentioned, this is the closest relative. It is used when particles settle out of a liquid. 침전물 is very common in medical contexts (like sediment in a urine sample) or industrial chemical processes. If the focus is on the act of settling from a solution, use this.
찌꺼기 (Residue / Dregs / Scraps): This is the everyday, casual word. It refers to what is left over after the useful part has been taken. It can be food scraps, coffee grounds, or even metaphorical 'scum' of society. Use this at home or in the kitchen.
앙금 (Dregs / Sediment / Grudge): This word is fascinating. Literally, it’s the starch or paste that settles at the bottom of a liquid (like in traditional Korean cooking). Metaphorically, it refers to 'bad feelings' or a 'grudge' that settles in one's heart after an argument. '마음에 앙금이 남다' means to still have hard feelings.
부유물 (Suspended Solids): The opposite of 퇴적물 in a way. These are particles that are floating in the water and haven't settled yet. If a river is murky because of floating dirt, you talk about 부유물.

Word	Best For...	Register
퇴적물	Rivers, Geology, Layers	Formal/Scientific
침전물	Chemistry, Medicine, Solutions	Formal/Technical
찌꺼기	Coffee, Food, Trash	Informal/Casual
앙금	Cooking, Emotions (Grudges)	Neutral/Literary

By expanding your vocabulary with these alternatives, you can describe the physical world with much higher resolution. Instead of just saying 'dirt in the water,' you can specify if it's geological sediment (퇴적물), floating debris (부유물), or chemical precipitate (침전물).

小贴士

Learn Hanja

Learning '적' (accumulate) helps you understand words like '축적' (accumulation) and '면적' (area).

Passive Voice

Always remember that sediment 'is piled up' (쌓이다), it doesn't 'pile' itself up in Korean grammar.

News Keywords

When you hear '수질' (water quality) or '강물' (river water), listen for '퇴적물' nearby.

Clear Vowels

Make sure to distinguish '퇴' from '태'. 'T-way' is a good approximation for '퇴'.

Scientific Tone

Use this word in essays about nature to instantly boost your academic tone.

Documentary Practice

Watch Korean nature documentaries on YouTube; they are full of this word.

Toe-Jeok

Think of a 'Toe' touching a 'Jack' in the water. Toe-Jeok-Mul.

Vs. 찌꺼기

Sediment is for the Earth; Dregs are for the Kitchen.

Textbook Search

记住它

记忆技巧

Think of 'TOE' (퇴) touching a 'JACK' (적) - 'TOE-JEOK'. Imagine your toe touching a pile of sand (sediment) at the bottom of a pool. 'Mul' (물) means water, so it's 'Toe-Jack-Water stuff'.

常见问题

10 个问题

Technically, particles falling from the air can be called '퇴적물' in a scientific sense, but usually, '강하 분진' (falling dust) or '미세먼지' is used for air. '퇴적물' strongly implies a liquid environment like water.

흙 is the general word for soil. 퇴적물 is a specific term for soil/sand that has been moved by water or wind and then settled. All sediment is made of 'earth' (흙/모래), but not all soil is 'sediment' until it settles somewhere new.

No, that would sound very strange. Use '커피 찌꺼기' for coffee grounds or '앙금' if you are talking about the very fine silt at the bottom of a traditional drink.

In Korean, nouns don't have a mandatory plural form. '퇴적물' can mean one layer of sediment or a million grains of sand. Context tells you the quantity.

It is '퇴적암' (toe-jeok-am). The 'am' (암) comes from '암석' meaning rock.

Rarely. You might use it if you are talking about a serious environmental problem or a science project, but in a casual chat about cleaning, you'd use '찌꺼기' or '먼지'.

堆 (퇴 - pile), 積 (적 - accumulate), 物 (물 - thing).

Yes, in literature, it can represent the 'buildup' of time, memories, or even social problems, though this is a very formal and poetic usage.

The most common verb is '쌓이다' (to be piled up). You can also use '분석하다' (analyze) or '제거하다' (remove).

Yes. 퇴적 (sedimentation) is usually a physical process of piling up. 침전 (precipitation/settling) is the act of sinking to the bottom, often in a chemical or controlled context.
