توضیح 粒子 in your Level:

At the A1 level, you don't need to use the word 粒子 (ryūshi) very often. It is a more advanced word than 'tsubu' (grain). However, you might see it in very simple contexts like science picture books or basic weather reports. Think of it as 'a very, very small bit of something.' For example, if you see sand on the beach, each tiny piece is a 粒子. If you see dust in the air when the sun shines through the window, those are also 粒子. At this stage, just remember that it means 'tiny bit' and it's a noun. You might see it written in kanji (粒子) or hiragana (りゅうし). It is often used with the word 'chiisai' (small) or 'kirei' (pretty/clean). For example, 'chiisai ryūshi' means 'small particle.' You don't need to worry about the scientific details yet. Just know that it's a word for things that are almost too small to see. It's a good word to recognize if you like looking at science books or if you are interested in how things are made. In Japanese, we often use the word 'tsubu' for things like rice or rain, but 'ryūshi' is for even smaller things like dust or the 'dots' in a picture. If you can recognize the kanji 粒 (grain) and 子 (child/small), you can guess that it means a 'small grain.' This is a great way to start building your academic Japanese vocabulary early on!

At the A2 level, you can start to understand the difference between 粒子 (ryūshi) and the simpler word 粒 (tsubu). While 粒 is for things you can easily pick up, like a grain of rice or a bean, 粒子 is for things that are much smaller, like dust, smoke, or very fine sand. You might hear this word in weather reports about 'yellow dust' (kōsa) or air pollution. In these cases, the news will talk about 'particles in the air.' You can use 粒子 in simple sentences to describe things that are very fine. For example, 'Kono suna no ryūshi wa totemo chiisai desu' (The particles of this sand are very small). You might also see it on the back of a bottle of face wash or powder, where it describes the 'fine grains' that help clean your skin. At this level, focus on using it as a noun to describe the texture of fine materials. It's also helpful to know that 粒子 is a 'kango' (Chinese-origin word), which makes it sound a bit more formal and precise than 'tsubu.' If you use 粒子 instead of 'tsubu' when talking about something like flour or dust, you will sound more like a native speaker who has a good grasp of descriptive language. Try to look for this word when you are at a drugstore or looking at a science museum exhibit. It's a very useful word for describing the physical world around you in a more detailed way.

At the B1 level, you should be comfortable using 粒子 (ryūshi) in more specific contexts, such as photography, basic science, and environmental issues. This is the level where you move beyond just 'tiny bits' and start thinking about 'particulate matter.' For example, if you are interested in photography, you will use 粒子 to talk about the 'grain' of a photo. A sentence like 'Kono shashin wa ryūshi ga arai desu ne' (This photo is quite grainy, isn't it?) is a very natural way to use the word. In a B1 level science class or article, you will see 粒子 used to describe atoms or molecules in a general sense. You should also be aware of the term 'biryūshi' (fine particles), which is often used in discussions about air quality and health. You can start using 粒子 with more complex verbs, such as 'ryūshi o kansoku suru' (to observe particles) or 'ryūshi ga fuyū shite iru' (particles are floating). This word is also common in the cosmetics industry. If you read a product description for a high-end foundation, it might say 'ryūshi ga komakai' (the particles are fine), implying that the product will look smooth on the skin. At this stage, you should be able to distinguish between 粒子 and other related words like 粉末 (funmatsu - powder) and 埃 (hokori - dust). Remember that 粒子 refers to the individual units, while 粉末 refers to the whole substance. Using 粒子 correctly will significantly improve your ability to discuss technical and descriptive topics in Japanese.

At the B2 level, 粒子 (ryūshi) becomes a key vocabulary item for academic and professional discussions. You are expected to understand its role in physics, chemistry, and advanced technology. You will encounter terms like 素粒子 (soryūshi - elementary particles), 粒子加速器 (ryūshi kasokuki - particle accelerator), and 粒子性 (ryūshisei - particle-like nature, as in the wave-particle duality of light). At this level, you should be able to read and discuss articles about environmental science, such as the impact of PM2.5 (微小粒子状物質) on public health. You will also see 粒子 used in industrial contexts, such as the manufacturing of semiconductors or the development of new materials where 'particle size control' (粒径制御 - ryūkei seigyo) is crucial. Your usage of the word should reflect this precision. For example, instead of just saying something is 'fine,' you might discuss the 'distribution of particles' (粒子の分布) or the 'surface area of the particles' (粒子の表面積). In literature or high-level journalism, 粒子 might be used metaphorically to describe the 'texture' of an experience or the 'fragments' of a memory, though this is less common than its literal scientific use. You should also be aware of how 粒子 is used in digital imaging to describe 'noise' and how it differs from 'pixels' (goso). Mastery of 粒子 at this level means being able to use it accurately in a variety of specialized fields, from quantum mechanics to high-end skincare marketing.

At the C1 level, your understanding of 粒子 (ryūshi) should be nuanced and deeply integrated into your specialized vocabulary. You should be able to follow complex scientific lectures or read peer-reviewed papers where 粒子 is a fundamental concept. This includes understanding the nuances of 'particle physics' (粒子物理学) and the philosophical implications of 'particulate' vs. 'continuous' models of reality. You will encounter 粒子 in discussions about nanotechnology (ナノ粒子), where the properties of matter change at the particle level. In this context, you might discuss 'quantum dots' or 'particle-surface interactions.' Furthermore, you should be able to use 粒子 in sophisticated metaphorical ways in creative writing or high-level discourse. For instance, describing the 'particles of light' (光の粒子) in a sunset to evoke a specific visual texture, or talking about the 'particles of time' in a philosophical essay. You should also be familiar with related technical terms like 粒子径 (particle diameter), 粒子密度 (particle density), and 粒子間力 (interparticle forces). At the C1 level, you are not just using the word; you are manipulating the concept to express complex ideas. You should also be able to explain the difference between 粒子 and related concepts like 'colloid' (コロイド) or 'aerosol' (エアロゾル) in Japanese. Your ability to use 粒子 in formal debates or professional presentations will demonstrate a high level of linguistic and conceptual sophistication.

At the C2 level, 粒子 (ryūshi) is a word you use with total precision and native-like intuition across all possible domains. You are capable of engaging in high-level research or professional work in fields like theoretical physics, materials science, or environmental engineering where 粒子 is a core term. You understand the historical development of the term and how it relates to the evolution of scientific thought in Japan. You can effortlessly switch between the literal, scientific use and the more abstract or poetic uses found in modern Japanese literature. For example, you might analyze how a writer uses the 'coarseness of particles' (粒子の荒さ) to symbolize the breakdown of a relationship or the harshness of a landscape. You are also familiar with the most obscure compound words and technical jargon involving 粒子, such as 粒子状物質排出基準 (emission standards for particulate matter) or 粒子法 (particle method in computer simulation). Your command of the word allows you to appreciate the subtle differences in tone when a scientist uses 粒子 versus when a poet uses it. At this level, you could potentially write a thesis or a technical manual in Japanese that centers on the behavior of particles. You have a complete grasp of the word's collocations, its role in various registers of speech, and its place within the broader landscape of the Japanese language. 粒子 is no longer just a vocabulary word; it is a precise tool in your extensive linguistic arsenal.

粒子 در ۳۰ ثانیه

粒子 (ryūshi) means 'particle' or 'grain' and is used for extremely small bits of matter in scientific or technical contexts.
It is a formal noun, distinct from the everyday word 'tsubu' (grain), and is common in physics, chemistry, and photography.
You will often hear it in weather reports regarding air pollution (PM2.5) or see it on high-quality cosmetic packaging.
Key phrases include '粒子が細かい' (fine particles) and '素粒子' (elementary particles), essential for academic Japanese.

The Japanese word 粒子 (りゅうし - ryūshi) is a sophisticated noun that translates primarily to 'particle' or 'grain' in English. While a beginner might first learn the word 粒 (つぶ - tsubu) for a single grain of rice or a drop of rain, 粒子 is its more academic, scientific, and technical cousin. It refers to a minute portion of matter, often so small that it is considered a fundamental unit within a specific context. Whether you are discussing the physics of the universe, the chemistry of a solution, the quality of a digital photograph, or the fine dust floating in a sunbeam, 粒子 is the indispensable term for describing these tiny constituents. It is a word that bridges the gap between the visible world of sand and dust and the invisible world of atoms and subatomic entities.

Scientific Context: In physics and chemistry, 粒子 is used to describe atoms, molecules, and subatomic particles. For example, 'elementary particles' are called 素粒子 (そりゅうし - soryūshi). This usage is precise and formal, appearing in textbooks and research papers to define the building blocks of matter.

この物質は非常に細かい粒子で構成されています。(This substance is composed of extremely fine particles.)

Photography and Imaging: When discussing film photography or digital image sensors, 粒子 refers to the 'grain.' If a photo looks 'grainy' or 'noisy,' a Japanese speaker might say 粒子が荒い (りゅうしがあらい - ryūshi ga arai), meaning the particles are coarse or prominent.

Furthermore, 粒子 is frequently encountered in environmental science, particularly regarding air quality. The term PM2.5 refers to 微小粒子状物質 (びしょうりゅうしじょうぶっしつ), or fine particulate matter. In this context, the word carries a nuance of health and safety, describing invisible threats that we breathe in. It is also used in the cosmetics industry to describe the 'fineness' of powders, where smaller particles often equate to a smoother application and higher quality product. Understanding 粒子 allows a learner to navigate high-level discussions ranging from skincare to quantum mechanics.

空気中の微細な粒子が光を散乱させている。(Fine particles in the air are scattering the light.)

Industrial Usage: In manufacturing, the size of particles (粒径 - ryūkei) is a critical factor for materials like cement, paint, and medicine. Controlling the 粒子 size ensures consistency and effectiveness in the final product.

インクの粒子を小さくすることで、より鮮明な印刷が可能になります。(By making the ink particles smaller, clearer printing becomes possible.)

砂の粒子が靴の中に入ってしまった。(Particles of sand got into my shoes.)

高エネルギーの粒子が衝突した。(High-energy particles collided.)

Using 粒子 correctly requires understanding its role as a formal noun. It rarely stands alone in casual conversation; instead, it is often modified by adjectives like 細かい (こまかい - fine), 小さい (ちいさい - small), or 微細な (びさいな - microscopic). Grammatically, it functions like any other noun, often followed by particles like が, を, or の to connect it to other parts of the sentence. Because it is a Sino-Japanese word (kango), it carries a level of gravity and precision that makes it suitable for academic, professional, and literary settings.

Describing Size and Texture: When you want to describe how fine or coarse something is, you use 粒子 with size-related adjectives. '粒子が細かい' (fine particles) is a very common phrase used for everything from flour to face powder.

この小麦粉は粒子が細かく、お菓子作りに最適です。(This flour has fine particles and is ideal for making sweets.)

Scientific Action: In physics, 粒子 is the subject or object of actions like 衝突する (しょうとつする - to collide), 加速する (かそくする - to accelerate), or 放出する (ほうしゅつする - to emit/release).

太陽から放出された粒子がオーロラを作り出す。(Particles emitted from the sun create auroras.)

In the realm of digital art and photography, 粒子 is often used to describe the 'texture' of an image. If you are editing a photo and want to add a vintage look, you might 'add grain' (粒子を加える). Conversely, if an image is too noisy, you might try to 'reduce the grain' (粒子を抑える). This metaphorical use of the word highlights its versatility beyond pure science.

デジタル写真の粒子を調整して、フィルムのような質感を出した。(I adjusted the grain of the digital photo to give it a film-like texture.)

Environmental Monitoring: When talking about pollution, 粒子 is often paired with words like 浮遊 (ふゆう - floating/suspended). '浮遊粒子' refers to particles suspended in the air or water.

工場から排出される汚染粒子が問題になっている。(Pollutant particles emitted from factories are becoming a problem.)

顕微鏡でしか見えないほど小さな粒子です。(These are particles so small they can only be seen with a microscope.)

水の中の不純物粒子を取り除くフィルター。(A filter that removes impurity particles from the water.)

While 粒子 might seem like a word reserved for lab coats and lecture halls, it appears surprisingly often in daily Japanese life, provided you know where to look. One of the most common places is the daily weather report or news broadcast. In Japan, air quality is a significant public concern, especially regarding yellow dust (黄砂 - kōsa) from the continent or PM2.5. News anchors will frequently use the term 粒子 to describe these airborne particles, warning citizens to wear masks or avoid hanging laundry outside.

News and Weather: '微小粒子状物質' (PM2.5) is a term every Japanese adult knows. You will hear it during the weather segment of the morning news, often accompanied by maps showing particle density across the archipelago.

明日は黄砂の粒子が飛来する見込みです。(Tomorrow, particles of yellow dust are expected to fly in.)

Cosmetics and Skincare: If you walk into a Japanese drugstore like Matsumoto Kiyoshi, you will see 粒子 on the packaging of powders, foundations, and sunscreens. Marketing copy often boasts about 'nanoparticles' (ナノ粒子) that penetrate the skin better or 'fine particles' that provide a natural finish.

Another surprising venue for this word is the world of hobbyists—specifically, photographers and model builders. In photography magazines, reviewers discuss the 粒子感 (りゅうしかん - graininess) of different film stocks or digital sensors. For model builders (Gunpla enthusiasts, for instance), the 粒子 size of the metallic paint they use is a frequent topic of discussion on forums and YouTube tutorials. They want the 'metal particles' to be as fine as possible to maintain the scale of the miniature robot.

このファンデーションは粒子が非常に細かく、肌に密着します。(This foundation has very fine particles and adheres well to the skin.)

Pop Culture and Sci-Fi: Anime fans will recognize 粒子 from various sci-fi series. Whether it's 'GN Particles' in Gundam 00 or 'Spirit Particles' (霊子 - reishi, a related concept) in Bleach, the idea of fundamental particles with special powers is a staple of Japanese fiction.

謎の粒子がレーダーを妨害している！(Mysterious particles are jamming the radar!)

このスプレーは、銀粒子の力で消臭します。(This spray deodorizes with the power of silver particles.)

高感度フィルムは粒子が目立ちやすい。(High-speed film tends to have noticeable grain.)

One of the most common mistakes learners make with 粒子 is confusing it with the simpler word 粒 (つぶ - tsubu). While both refer to small, grain-like objects, their usage is quite different. 粒 is used for everyday objects you can see and touch individually, like a grain of rice (米粒 - kome-tsubu), a drop of sweat (汗の粒 - ase no tsubu), or a pill (薬の粒 - kusuri no tsubu). 粒子, on the other hand, is used for things that are usually too small to see individually or when speaking in a scientific/technical capacity. Using 粒子 for a single grain of rice would sound very strange—almost like you are looking at your dinner through a microscope.

Confusing 粒子 with 粒: Incorrect: ご飯の粒子 (Gohan no ryūshi). Correct: ご飯の粒 (Gohan no tsubu). 粒子 is for 'matter' in a general sense; 粒 is for specific, countable grains.

雨の粒が窓に当たっている。(Raindrops are hitting the window.) [Not 粒子]

Confusing with Grammar Particles: In English, we use the word 'particle' to describe grammatical markers like 'wa', 'ga', and 'o'. However, in Japanese, these are called 助詞 (じょし - joshi), NOT 粒子. If you tell a Japanese teacher you are struggling with 'particles' and use the word 粒子, they will think you are having trouble in your physics class, not your grammar class.

Another mistake involves the scale of the particle. Sometimes learners use 粒子 when they should use 分子 (ぶんし - molecule) or 原子 (げんし - atom). While 粒子 is a broad term that can include atoms and molecules, if you are specifically talking about H2O, you should use 分子. If you are talking about the element Oxygen, use 原子. 粒子 is best used when the specific chemical structure isn't the focus, but rather the physical state of being a 'tiny bit of matter.'

水は水素と酸素の原子からできています。(Water is made of hydrogen and oxygen atoms.) [Not 粒子, though they are particles]

Overusing Technical Language: Using 粒子 in a very casual setting, like describing crumbs on a table, can sound overly dramatic or 'nerdy.' In such cases, 屑 (くず - kuzu/crumbs) or just 'dirty' (汚れている) is more natural.

テーブルにパンのくずが落ちている。(There are bread crumbs on the table.) [Not 粒子]

この薬は粒が大きくて飲みにくい。(This medicine has large pills and is hard to swallow.) [Not 粒子]

光は波であり、粒子でもある。(Light is a wave and also a particle.) [Correct scientific use]

Japanese has several words that describe small bits of matter, and choosing the right one depends on the context and the size of the object. 粒子 is the most general scientific term, but let's look at how it compares to its synonyms and related terms.

粒子 (Ryūshi) vs. 粒 (Tsubu): As discussed, 粒子 is technical/scientific, while 粒 is everyday/tangible. You can count 粒 (one grain, two grains), but 粒子 is often treated as a collective substance.

粒子 (Ryūshi) vs. 粉末 (Funmatsu): 粉末 means 'powder.' While a powder is made of particles, 粉末 refers to the substance as a whole (like protein powder or gunpowder), whereas 粒子 refers to the individual tiny bits that make up that powder.

この粉末は粒子が非常に細かい。(This powder has very fine particles.)

粒子 (Ryūshi) vs. 微粒子 (Biryūshi): 微粒子 simply means 'fine particle' or 'micro-particle.' The prefix 微 (bi) means 'minute' or 'tiny.' It is often used interchangeably with 粒子 when emphasizing extreme smallness, especially in environmental or medical contexts.

In physics, you will also encounter 素粒子 (そりゅうし - soryūshi), which means 'elementary particle' (like quarks or electrons). This is the most fundamental level of matter. In chemistry, you have 分子 (ぶんし - molecule) and 原子 (げんし - atom). While these are all 'particles,' using the specific term is always preferred in a scientific context.

宇宙の始まりには、素粒子しか存在しなかった。(At the beginning of the universe, only elementary particles existed.)

粒子 (Ryūshi) vs. 埃 (Hokori): 埃 means 'dust.' Dust is composed of particles (埃の粒子), but if you are just talking about cleaning your room, you would say 埃, not 粒子.

棚に埃がたまっている。(Dust is accumulating on the shelf.)

砂漠の砂は、非常に細かい粒子でできている。(Desert sand is made of very fine particles.)

この空気清浄機は、花粉の粒子まで除去します。(This air purifier even removes pollen particles.)

اشتباهات رایج

Using 粒子 for grammar particles. → 助詞 (joshi)
This is the #1 mistake for English speakers. 粒子 is for physics; 助詞 is for language.
Saying 'Gohan no ryūshi' for a grain of rice. → ご飯の粒 (Gohan no tsubu)
粒子 is too technical for food. Use 粒 for everyday countable items.
Confusing 粒子 with 漁師 (ryoushi - fisherman). → 粒子 (ryūshi)
The pronunciation is similar, but the long vowel and pitch accent are different. Context usually helps.
Using 粒子 when you mean 'powder' (the substance). → 粉末 (funmatsu) or 粉 (kona)
If you want the whole powder, use 粉末. If you want the individual bits, use 粒子.
Miswriting the kanji 粒. → 粒 (with 米 radical)
Don't forget the 'rice' radical on the left. It's essential for the meaning.

نکات

Learn the Radicals

The kanji 粒 has the rice radical (米). This helps you remember it's about small grains. The 子 means 'small thing.' Together: 'small grain thing' = particle.

Scientific Tone

Use 粒子 when you want to sound objective or scientific. It's the difference between saying 'bits of dust' and 'dust particles.'

Image Quality

If you are into photography, learn '粒子感' (ryūshikan). It's a great way to describe the texture of a photo to Japanese friends.

Avoid Grammar Confusion

Always remember: Japanese grammar 'particles' are 助詞 (joshi). If you say 粒子 in a Japanese class, the teacher will be confused.

Health Awareness

When you hear 'PM2.5' on the news, listen for '粒子.' It will help you understand warnings about air pollution.

Ryūshi vs. Tsubu

If you can see it and count it easily (like a bean), use 粒 (tsubu). If it's microscopic or technical, use 粒子 (ryūshi).

Writing Practice

Practice writing 粒子. It's a common word in N2/N1 exams and academic writing.

Pitch Accent

The pitch drops after 'ryū.' Practice saying 'RYŪ-shi' to sound more natural.

Drugstore Shopping

Look for 粒子 on makeup boxes. It usually means the product is 'fine' and 'smooth.'

Sci-Fi Terms

Many anime use '粒子' for power systems. It's a fun way to see the word in action outside of a textbook.

روش یادسپاری

Think of a 'RYU' (dragon) that is so small it fits inside a 'SHI' (she/her) pocket. It's a tiny dragon particle!

تداعی تصویری

Imagine looking through a magnifying glass at a grain of sand. As you zoom in, the 'grain' (粒) becomes a scientific 'particle' (粒子).

چالش

Try to find three items in your room that are made of 粒子 (like flour, dust, or salt) and describe them using '粒子が細かい'.

ریشه کلمه

The word 粒子 is a Sino-Japanese compound (kango). The first character 粒 (ryū) means 'grain' or 'drop,' and the second character 子 (shi) is a common suffix used for small objects or children.

معنای اصلی: Originally, it referred to any small grain-like object, but its modern scientific meaning developed as Japanese scholars translated Western scientific texts during the Meiji era.

Japonic (Sino-Japanese vocabulary).

بافت فرهنگی

No specific sensitivities, but be careful not to use it for 'crumbs' or 'dirt' in a way that sounds overly clinical or strange.

In English, 'particle' can also mean a grammar word (like 'to' or 'up'). In Japanese, this is NEVER 粒子; it is 'joshi.'

PM2.5 (微小粒子状物質) - A major environmental topic in Japan. GN Particles (GN粒子) - From the anime 'Mobile Suit Gundam 00'. Higgs Boson (ヒッグス粒子) - Widely reported in Japanese media as the 'God particle'.

سوالات متداول

10 سوال

No, that would sound very strange. For a grain of rice, use 'kome-tsubu' (米粒). 粒子 is reserved for much smaller or scientific contexts.

No. In English, we say 'grammar particles,' but in Japanese, these are called '助詞' (joshi). Using 粒子 for grammar is a common mistake for English learners.

It means the image is 'grainy.' This can be a negative thing (noise) or a stylistic choice to make a photo look vintage.

微粒子 (biryūshi) specifically means 'fine' or 'micro' particles. 粒子 is the general term for any particle, regardless of size.

It is '粒子加速器' (ryūshi kasokuki). This is a common term in physics news.

It is common in specific contexts like science, news (weather/pollution), and photography. It is not used every day like 'water' or 'bread,' but every Japanese adult knows it.

Usually, 'tsubu' or 'shizuku' is used for drops. However, in technical contexts like 'aerosol particles,' 粒子 can be used for tiny liquid droplets.

素粒子 (soryūshi) means 'elementary particle.' These are the most basic building blocks of the universe, like quarks and electrons.

It suggests that the powder or cream is very fine and high-quality, allowing it to blend smoothly into the skin without looking 'cakey'.

Yes, the kanji 子 is the same. In this context, it acts as a suffix meaning 'small thing' or 'unit'.
