توضیح 浸食 in your Level:

At the A1 level, '浸食' (erosion) is a very difficult word that you usually don't need to speak. However, you can think of it as 'water breaking land.' In Japan, there are many mountains and rivers. Sometimes, when it rains a lot, the water takes the soil away. This is '浸食.' If you see a picture of a river making a big hole in the ground, that is the action of this word. You can remember it as 'water + eat.' The water 'eats' the ground. It is a formal word, so you will see it in books or on TV, but for now, just knowing it means 'the ground changing because of water' is enough. You don't need to use it in daily conversation yet.

At the A2 level, you might start seeing '浸食' in simple science books or news headlines. It is a noun, but you can add 'suru' to make it a verb. It means 'erosion.' For example, 'The rain erodes the mountain' (雨が山を浸食する). You should notice the two kanji: 浸 (soak) and 食 (eat). This helps you understand that it's about water slowly wearing things away. You might use it when talking about nature or a trip to a famous place like a canyon. It's more formal than 'kezureru' (to be shaved off), so using it makes you sound more like a serious student. Just remember it usually involves water, wind, or ice.

At the B1 level, you should be able to recognize '浸食' and use it in specific contexts like geography or environmental discussions. This is a CEFR B1 word because it is essential for discussing social issues like climate change and land protection in Japan. You should understand the difference between '浸食' (geological erosion) and '侵食' (encroachment/invasion). At this level, you should also be comfortable using the passive voice: '海岸が浸食されている' (The coast is being eroded). This is a common way to describe environmental problems. You will encounter this word frequently in JLPT N3 and N2 reading materials, especially those focused on nature or technology.

At the B2 level, you are expected to use '浸食' accurately in academic or professional settings. You should understand its technical nuances, such as its role in the 'Three Actions of a River' (浸食, 運搬, 堆積). You should also be able to use compound nouns like '浸食作用' (erosive action) or '浸食地形' (eroded terrain). At this level, you should be sensitive to the choice between 浸食, 腐食 (corrosion), and 摩耗 (mechanical wear). In a debate about environmental policy, you might use '浸食' to explain the loss of agricultural land. Your understanding should extend to how human activities, like deforestation, can accelerate 'shinshoku.'

At the C1 level, you should have a nuanced understanding of '浸食' and its metaphorical possibilities. While primarily a geological term, in high-level literature or socio-political commentary, it can describe the 'erosion' of cultural values or the 'eating away' of a person's identity. You should be able to read complex scientific papers or white papers from the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) that discuss 'shinshoku' in detail. You should also understand the historical development of the kanji and why certain publications prefer 侵食 over 浸食. Your usage should be indistinguishable from a native speaker in formal writing.

At the C2 level, '浸食' is a tool for precise scientific and philosophical expression. You can discuss the granular differences between hydraulic action, abrasion, and attrition—all components of '浸食'—using appropriate Japanese terminology. You can analyze the impact of 'shinshoku' on archaeological sites or its role in planetary geology (e.g., erosion on Mars). You are also capable of using the word in highly abstract, poetic contexts where the 'soaking and eating' nuance of the kanji 浸食 adds a specific layer of meaning that 侵食 would not. You can navigate the most dense academic texts on geomorphology with ease.

浸食 در ۳۰ ثانیه

浸食 (Shinshoku) means geological erosion caused by water, wind, or ice.
It is a formal noun that can also function as a Suru-verb (to erode).
Commonly used in geography, news, and discussions about environmental issues.
Distinct from 'fushoku' (corrosion/rust) and 'mahou' (friction wear).

The Japanese word 浸食 (しんしょく - Shinshoku) is a specialized noun that describes the geological and physical process of erosion. At its core, it refers to the gradual wearing away or removal of soil, rock, or land surfaces by the persistent action of natural elements such as flowing water, wind, ice, or waves. In a Japanese linguistic context, this word is frequently encountered in geography textbooks, environmental news reports, and scientific discussions regarding the changing landscape of the Japanese archipelago. Because Japan is an island nation with rugged coastlines and high rainfall, the concept of shinshoku is a significant part of the national consciousness regarding land management and disaster prevention.

Geological Context: In earth sciences, 浸食 refers to the mechanical and chemical processes where the earth's surface is worn down. This includes 'river erosion' (河川浸食) where the flow of water carves out valleys, and 'coastal erosion' (海岸浸食) where the relentless Pacific or Japan Sea waves reclaim land from the shore.

長年の波の浸食によって、その奇岩は形成された。(That strange rock formation was created by years of wave erosion.)

Beyond the literal physical wearing of rocks, the term can occasionally be used metaphorically in literature to describe the 'erosion' of one's heart, peace of mind, or even the gradual disappearance of traditional customs under the pressure of modernity. However, it is important to distinguish 浸食 from its homophone 侵食. While they are often used interchangeably in modern Japanese, 浸食 (using the 'soak' kanji) traditionally emphasizes the action of liquid or natural forces, whereas 侵食 (using the 'invade' kanji) often implies a more aggressive or hostile encroachment, such as a disease invading a body or a company infringing on a market. For learners at the B1 level, mastering 浸食 involves understanding its environmental implications and recognizing it in news segments about climate change and rising sea levels.

Chemical Aspect: In industrial or chemical contexts, 浸食 can refer to the corrosion of materials when exposed to acidic liquids or harsh environments, though 'fushoku' (腐食) is more common for rust.

酸性雨が石像の表面を浸食している。(Acid rain is eroding the surface of the stone statues.)

Understanding the kanji is also vital. The first character 浸 (shin) means to 'soak,' 'steep,' or 'immerse.' The second character 食 (shoku) means to 'eat.' Together, they paint a vivid picture of something being 'soaked and eaten away' by water. This visual mnemonic helps learners remember that this specific version of 'shinshoku' is almost always tied to the action of fluids. In daily life, you might see this word on warning signs near cliffs or in documentaries about the Grand Canyon. It is a formal, technical word, so you won't typically hear it in casual conversation unless the topic is specifically about nature or environmental issues. However, its frequency in written media makes it indispensable for intermediate learners aiming for literacy.

Using 浸食 correctly requires understanding its grammatical role as a noun that frequently functions as a Suru-verb (浸食する). When used as a noun, it often appears in compound words or as the subject/object of a sentence. When used as a verb, it describes the active process of erosion taking place. It is primarily used in the passive voice (浸食される) when describing land or objects that are being affected by natural forces, which is the most common way you will encounter it in descriptive writing.

Grammatical Pattern: Noun + の + 浸食: This pattern is used to specify what is being eroded or what is doing the eroding. For example, '海岸の浸食' (erosion of the coast) or '雨による浸食' (erosion by rain).

この地域では、深刻な海岸浸食が問題になっている。(In this region, serious coastal erosion has become a problem.)

When you want to describe the action of eroding, you use the verb form shinshoku-suru. This is often used in scientific explanations. For instance, '川の水が土手近くの土地を浸食する' (River water erodes the land near the banks). In passive contexts, which are very frequent in news reports, you would say '土地が浸食される' (The land is eroded). This emphasizes the impact of the natural disaster on the environment or human property. It is also common to see it paired with the particle 'によって' (by/due to) to indicate the cause of the erosion.

Grammatical Pattern: ~によって浸食される: Used to describe the victim of erosion and the force responsible. '岩が波によって浸食された' (The rock was eroded by the waves).

強風が砂丘を少しずつ浸食していった。(The strong winds gradually eroded the sand dunes.)

Another important usage is in compound nouns. Words like 浸食作用 (shinshoku sayou) which means 'erosive action' or 'the process of erosion' are common in academic texts. If you are discussing the prevention of erosion, you might use 浸食防止 (shinshoku boushi). These compounds allow for very precise communication in professional or academic settings. Beginners should focus on the noun form first, while intermediate students should practice the passive 'sareru' form to describe environmental changes they observe in photos or news stories.

氷河の浸食によってU字谷が作られた。(U-shaped valleys were created by glacial erosion.)

You are most likely to encounter 浸食 in educational, scientific, and news-related environments. In Japan, because of the country's geography—characterized by steep mountains and a coastline prone to typhoons—erosion is a constant concern for civil engineers and environmentalists. Therefore, if you watch NHK News or read a Japanese newspaper like the Asahi Shimbun, you will frequently see this word in the context of 'disaster prevention' (防災 - bousai). Reports on how a typhoon has eroded a riverbank or how rising sea levels are eroding beaches in Shizuoka or Niigata are common themes.

News and Media: Journalists use 浸食 to explain why certain infrastructure is failing. '道路の下の土砂が浸食され、陥没した' (The soil under the road was eroded, causing a sinkhole).

テレビのニュースで、海岸線の浸食のニュースを見た。(I saw a news report on TV about the erosion of the coastline.)

In the classroom, 浸食 is a staple of 'Rika' (Science) and 'Chiri' (Geography) lessons. Students learn about the three main actions of a river: 運搬 (unpan - transport), 堆積 (taiseki - sedimentation), and 浸食 (shinshoku - erosion). This trio of words is often memorized together. If you visit a national park in Japan, such as the Tottori Sand Dunes or the rocky coasts of Wakayama, the informational plaques will almost certainly use 浸食 to explain the history of the landscape. For example, a sign might say, 'These cliffs were formed by the erosive power of the Kuroshio Current.'

In professional settings, such as construction or environmental consulting, the word is used with high frequency. Engineers discuss how to prevent the erosion of foundations using concrete blocks or vegetation. In these contexts, accuracy is key, and 浸食 provides that technical precision. Interestingly, you might also find the word in video games or fantasy novels that involve elemental magic. A 'water mage' might have a spell called 'Erosion' (浸食), though in such cases, the alternative kanji 侵食 is often preferred for its more 'aggressive' nuance. Regardless of the genre, the core meaning of 'wearing away' remains consistent.

理科の授業で、川の浸食作用について学んだ。(In science class, we learned about the erosive action of rivers.)

The most common mistake learners make with 浸食 is confusing it with its homophone 侵食. While they sound identical (both are 'shinshoku') and their meanings overlap significantly, there is a subtle but important difference in nuance and kanji usage. 浸食 (soak + eat) is primarily for physical, geological erosion by water or wind. 侵食 (invade + eat) is used for encroachment, such as a disease invading healthy tissue, one territory encroaching on another, or an abstract 'eating away' at someone's rights or time.

Confusing 浸食 vs. 侵食: Mistake: Using 浸食 to describe a virus. Correct: Use 侵食 (invasion). Mistake: Using 侵食 for a riverbank in a formal geology paper. Correct: Use 浸食 (soaking).

× 癌細胞が体を浸食する。(Wrong kanji for medical invasion)
○ 癌細胞が体を侵食する。(Correct: Encroachment/Invasion)

Another mistake is using 浸食 when 腐食 (fushoku) is more appropriate. 腐食 specifically means 'corrosion' or 'rotting,' usually referring to metals rusting or wood decaying due to chemical reactions. While erosion (浸食) is a physical wearing away, corrosion (腐食) is a chemical change. If you say a bridge is falling because of 'shinshoku,' a Japanese person might think the river is physically carrying the concrete away. If you say 'fushoku,' they will understand that the metal beams are rusting through.

Finally, learners sometimes confuse 浸食 with 摩耗 (mahou). 摩耗 refers to 'wear and tear' caused by friction between two solid objects, like the soles of your shoes wearing down or engine parts rubbing together. 浸食 is specifically for the action of natural elements like water and wind. If you use 'shinshoku' to describe your old tires, it will sound very strange, as if the rain has been eating them away like a mountain. Choosing the right word for 'wearing away' depends entirely on the agent of destruction.

× 靴の底が浸食された。(Wrong: Shoes don't erode like rocks)
○ 靴の底が摩耗した。(Correct: Wear and tear from friction)

To truly master 浸食, you must be able to distinguish it from several related terms that describe the destruction or alteration of surfaces. Depending on whether the cause is water, wind, friction, or chemicals, the appropriate word changes. Below is a comparison of synonyms and related terms often confused with 浸食.

侵食 (Shinshoku): The homophone mentioned earlier. While 浸食 is for geology/water, 侵食 is broader, covering encroachment of rights, territories, or biological invasion. In many general contexts, 侵食 is used for both.
腐食 (Fushoku): Corrosion or rot. This is used for chemical processes, such as acid eating through metal or bacteria causing wood to rot. Use this for rust on a car or a decaying fence.
風化 (Fuuka): Weathering. This is the process that precedes erosion. Weathering breaks down the rock into smaller pieces (via temperature changes or chemical reactions), while erosion (浸食) is the process of those pieces being carried away.

岩が風化し、その後、雨で浸食された。(The rock weathered, and then it was eroded by rain.)

For more colloquial or everyday situations, Japanese speakers often use simpler verbs. Instead of saying 'The coast is undergoing 浸食,' they might say 削れる (kezureru), which means 'to be shaved off' or 'to be worn down.' This is much more common in casual conversation. For example, '大雨で崖が削れた' (The cliff was worn away by heavy rain). Another alternative is 洗われる (awarareru), literally 'to be washed,' which is used poetically to describe rocks being smoothed by river water. Understanding these levels of formality allows you to choose the right word for the right audience.

この古い硬貨は、表面が摩耗して文字が読めない。(The surface of this old coin is worn down [mahou], so I can't read the letters.)

نکته جالب

The character 浸 has the 'water' radical (氵), which immediately tells the reader that the process involves liquid. The character 食 (eat) is used because the land appears to be 'consumed' by the natural forces.

Using 浸食 for worn-out shoes. → 靴が摩耗した (Shoes wore out).
Erosion is for natural forces; friction wear is 'mahou'.
Confusing the reading with 'inshoku' (eating and drinking). → 浸食 (Shinshoku) vs 飲食 (Inshoku).

نکات

Use the Passive Voice

When describing nature, use '浸食される' (is eroded). It sounds more natural because the land is the victim of the force.

Look for the Water

The '氵' radical in 浸 is your best clue. If the erosion involves water, this is the correct kanji.

Learn the Trio

Memorize 浸食 (erosion), 運搬 (transport), and 堆積 (sedimentation) together. They are the three main actions of a river.

News Watching

Watch Japanese weather reports after a typhoon. You will almost certainly hear 'shinshoku' used for riverbank damage.

Scientific Accuracy

In a formal essay, using 浸食 instead of 削れる will significantly raise the level of your writing.

The Eating Sea

Imagine the sea having a mouth and 'eating' (食) the 'soaked' (浸) cliffs. This matches the kanji perfectly.

Avoid Stress

Don't say SHIN-shoku or shin-SHOKU. Keep it flat and steady like a robot's voice. That's the correct pitch.

Rust vs. Erosion

If it's metal turning red, use 腐食. If it's a rock getting smaller in a river, use 浸食.

Headline Help

In news headlines, '浸食' might be shortened or part of a long compound. Look for the 'eat' character to spot it.

Coastal Pride

Japan is proud of its rocky coasts. When visiting, use 'shinshoku' to describe the beautiful rock formations to locals.

روش یادسپاری

Think of a 'Shin' (thin) piece of land being 'Shoku' (shocked/eaten) by a 'Soaking' (浸) wave. 浸食!

تداعی تصویری

Imagine a river shaped like a giant mouth slowly 'eating' (食) a soggy, 'soaked' (浸) riverbank.

چالش

Try to find three different photos of '浸食' online (like the Grand Canyon, a sea arch, and a worn-down mountain) and label them in Japanese.

ریشه کلمه

Composed of two Sino-Japanese (Kanji) characters: 浸 (Shin) and 食 (Shoku).

معنای اصلی: To soak and eat. This metaphorically describes how water 'eats' the land by soaking into it and breaking it down.

Sino-Japanese (Kango).

بافت فرهنگی

No specific sensitivities, but when discussing 'shinshoku' in the context of someone's property being lost, use a sympathetic tone.

In English, we often use 'erosion' broadly. In Japanese, speakers are more careful to distinguish between geological erosion (浸食) and metaphorical encroachment (侵食).

سوالات متداول

10 سوال

In modern Japanese newspapers and general use, 侵食 is often used for both meanings because it is part of the Joyo Kanji list for that specific reading. However, in science textbooks and formal geology, 浸食 is the correct and preferred term for water-related erosion.

No, that would be 'fushoku' (腐食). 浸食 implies that physical force like water or wind is carrying material away, not a chemical reaction like oxidation.

It is both. As a noun, it means 'erosion.' By adding 'suru,' it becomes a verb meaning 'to erode.' For example, 'Kaze ga shinshoku suru' (Wind erodes).

It is 'Kaigan Shinshoku' (海岸浸食). This is a very common phrase in Japan due to its long coastline.

Rarely. It's a formal word. In daily life, you'd likely say 'kezurete iru' (it's worn down) or 'kowarete iru' (it's broken).

Remember the 'water' radical on the left. Erosion usually involves water soaking (浸) the ground.

No, it can apply to soil, sand, ice, and even building materials if they are being worn away by natural elements.

The geological opposite is 'taiseki' (堆積), which means sedimentation or the accumulation of material.

Yes, it typically appears at the N2 level in the reading section, but B1 (N3) students should start learning it.

Usually, 'shinrai no shinshoku' uses the other kanji 侵食, as it's a metaphorical encroachment or invasion of trust.
