汚す
When you want to express the action of making something dirty or staining it, the verb 汚す (yogosu) is what you need. It's a transitive verb, which means it requires a direct object – something that gets dirtied or stained. Think of it like someone actively performing the action of making something unclean.
For example, if a child spills juice on their clothes, they 汚す (yogosu) their clothes. If a factory pollutes a river, it 汚す (yogosu) the river. The key is that there's an agent performing the action and an object receiving it.
When discussing environmental pollution, you'll often encounter 汚す (yogosu). This verb specifically refers to the act of making something dirty, whether it's a physical object or, in a broader sense, the environment.
For example, if you're talking about factories polluting rivers, you'd use 汚す. It's a versatile verb for describing the act of contamination or soiling.

The verb 汚す (yogosu) means 'to make dirty' or 'to stain'. It's a transitive verb, which means it acts on an object. Think of it as 'someone dirties something'. This word is quite common in daily life and you'll hear it in various situations.

§ Common Mistakes with 汚す (yogosu)
Let's talk about some common pitfalls when using 汚す (yogosu). This word can be tricky because Japanese often expresses things differently than English. Pay attention to these points, and you'll sound more natural.
§ Mistake 1: Confusing Transitive and Intransitive
This is a big one. 汚す (yogosu) is a transitive verb. That means someone or something does the dirtying. It takes a direct object, usually marked with the particle を (o).
- Transitive vs. Intransitive
- In Japanese, many verbs come in pairs: one transitive (the action is done to something) and one intransitive (the action happens by itself or to something without an external agent). For "to get dirty," the intransitive counterpart is 汚れる (yogoreru).
You use 汚す when someone or something actively makes something dirty. If something just gets dirty on its own, you use 汚れる (yogoreru). It's a subtle but important difference.
子供が服を汚した。(Kodomo ga fuku o yogoshita.)
The child dirtied their clothes. (The child was the agent of the action.)
服が汚れた。(Fuku ga yogoreta.)
The clothes got dirty. (The clothes got dirty on their own, or the agent is not specified.)
§ Mistake 2: Overusing 汚す for Minor Messes
While 汚す means "to make dirty," it often implies a noticeable or significant amount of dirt. For smaller, more common messes, other verbs or phrases might be more appropriate. For example, if you just spill a little water, you might use 濡らす (nurasu - to wet) or something similar, rather than 汚す, which suggests a more substantial "dirtying" or staining.
泥で靴を汚した。(Doro de kutsu o yogoshita.)
I dirtied my shoes with mud. (This is a significant amount of dirt.)
If you just spilled a few crumbs, 汚す might be too strong. Consider the degree of mess.
§ Mistake 3: Not understanding the nuance of "stain"
While 汚す can mean "to stain," it's a general term. If you want to be more specific about a permanent, hard-to-remove mark, you might use other words or descriptive phrases. 汚す itself covers both temporary dirt and more lasting stains, but context is key.
醤油がシャツを汚した。(Shōyu ga shatsu o yogoshita.)
Soy sauce stained the shirt. (Here it implies a stain, which is a type of dirtiness.)
§ Mistake 4: Using 汚す for figurative "dirtying" without caution
Just like in English, 汚す can be used figuratively for "sullying" or "defiling" someone's reputation, honor, or a sacred place. However, this usage is more formal or dramatic. Don't use it casually when you just mean "make a mess."
彼の名誉を汚す行為だ。(Kare no meiyo o yogosu kōi da.)
It's an act that sullies his honor. (Figurative use, formal.)
When learning, stick to its literal meaning first. The figurative uses will come more naturally as you advance.
§ Key Takeaways
- 汚す is transitive: someone or something *makes* something dirty.
- Its intransitive pair is 汚れる (yogoreru): something *gets* dirty.
- Use を (o) with 汚す to mark the direct object.
- Consider the degree of mess; 汚す implies noticeable dirt or stains.
- Be careful with figurative uses; they are more formal.
By keeping these points in mind, you'll avoid common mistakes and use 汚す more accurately and naturally in your Japanese conversations. Keep practicing!
§ Understanding 汚す (yogosu)
You're learning Japanese, and you've come across 汚す (yogosu). This word is a straightforward way to talk about making something dirty. It's a transitive verb, which means it takes a direct object. Someone or something does the dirtying.
- Japanese Word
- 汚す (yogosu)
- Definition
- To make dirty; to stain (transitive)
Think of it as the action of causing something to become unclean. Here are a couple of examples:
子供が服を汚した。
The child dirtied their clothes.
彼は手を汚した。
He got his hands dirty.
§ Similar Words and When to Use Them
Japanese has several words related to dirtiness or messiness. While 汚す (yogosu) is about making something dirty, it's good to know its counterparts and when to use them.
- 汚れる (yogoreru): This is the intransitive version of 汚す. It means 'to become dirty' or 'to get dirty'. The key difference is that no one is performing the action; the thing itself simply gets dirty.
服が汚れた。
The clothes got dirty.
- 汚い (kitanai): This is an い-adjective meaning 'dirty', 'filthy', or 'unclean'. It describes the state of something.
この部屋はとても汚い。
This room is very dirty.
- 汚す (kegasasu): While written with the same kanji as yogosu, when read as kegasasu, it carries a stronger nuance of defiling or disgracing, often in a moral or sacred sense. This is less common in everyday conversation for physical dirt.
When you're talking about spilling something and making a mess, you might also hear:
- こぼす (kobosu): To spill (transitive). This focuses specifically on liquid or granular things falling out.
- 散らかす (chirakasu): To scatter; to make a mess (transitive). This is about disarray and untidiness.
§ Key Takeaways
To sum it up:
- Use 汚す (yogosu) when someone or something actively makes something dirty.
- Use 汚れる (yogoreru) when something simply becomes dirty on its own.
- Use 汚い (kitanai) to describe something as dirty.
Focus on 汚す, 汚れる, and 汚い for most daily situations involving dirt. The others like kegasasu, kobosu, and chirakasu have more specific uses related to the type of mess or the nuance of defilement. Keep practicing, and you'll get the hang of it!
How Formal Is It?
"工場からの排水が川を汚濁する恐れがあります。 (The wastewater from the factory might pollute the river.)"

Examples by Level
子供たちは公園で遊んで、服を汚した。
The children played in the park and got their clothes dirty.
「汚す」is used here in its transitive form, meaning 'to make (something) dirty'.
彼は誤ってコーヒーをこぼし、書類を汚してしまった。
He accidentally spilled coffee and stained the documents.
「汚してしまった」adds a sense of regret or completion to the action.
ペンキの作業中に、壁に絵の具を汚さないように注意した。
During the painting work, I was careful not to get paint on the walls.
「汚さないように」expresses 'so as not to stain' or 'to avoid staining'.
土砂崩れで道路が汚れて、通行止めになった。
The road was dirtied by the landslide and became impassable.
Although the English translation uses 'dirtied', the Japanese implies the landslide made the road dirty, hence the transitive nature of 汚す.
彼女は新しい白いドレスを汚さないように、とても気をつけていた。
She was very careful not to get her new white dress dirty.
「汚さないように」is again used to express caution against staining.
インクが漏れて、私のカバンの中の教科書を汚してしまった。
The ink leaked and stained the textbook in my bag.
The subject 'ink' is doing the action of staining the 'textbook'.
雨の日に外出すると、服や靴が汚れることが多い。
When you go out on a rainy day, your clothes and shoes often get dirty.
This example uses the intransitive form 「汚れる」 meaning 'to get dirty' but is still related to the transitive '汚す' as the cause of something becoming dirty.
歴史的な建物の壁を落書きで汚すのは許されない行為です。
Defacing the walls of historical buildings with graffiti is an unforgivable act.
Here, 「汚す」 is used figuratively to mean 'to deface' or 'to disgrace' by making it dirty with graffiti.
Often Confused With
Intransitive form of 汚す. 汚す = to make dirty (transitive); 汚れる = to get dirty (intransitive).
Means 'to dye' or 'to intentionally color something', whereas 汚す is about making something unclean or accidentally staining it.
This is an adjective meaning 'dirty' or 'unclean'. It describes the state of being dirty, while 汚す is the verb for the action of making something dirty.
Easily Confused
Many learners confuse this with other similar-sounding verbs or verbs with related meanings, such as those that mean 'to get dirty' (intransitive). The kanji 汚 also appears in other words with similar connotations.
This verb is transitive, meaning *you* do the action of making something dirty. It requires a direct object. For example, you 'dirty' your clothes.
服を汚してしまった。 I accidentally dirtied my clothes.
This is often confused with 汚す because they share the same kanji 汚 and have very similar meanings.
This verb is intransitive, meaning something *becomes* dirty on its own, or by an external cause that isn't directly attributed to an agent. For example, your clothes 'get dirty'.
洗濯機が壊れて、服が汚れてしまった。 The washing machine broke, and my clothes got dirty.
Both 汚す and 染める can involve changing the color or appearance of something, leading to confusion about when to use which.
染める specifically means 'to dye' or 'to stain' in the sense of intentionally coloring something. While 汚す can mean 'to stain' accidentally, 染める implies a purposeful act of coloring.
髪を茶色に染めた。 I dyed my hair brown.
While the meanings are distinct, both verbs describe a state of deterioration or becoming undesirable. Learners might mix them up when talking about food or materials.
腐る means 'to rot' or 'to go bad', specifically referring to organic matter decaying. 汚す refers to something becoming physically unclean or tarnished.
この牛乳は腐っている。 This milk is rotten.
Both verbs describe harming or damaging something. The distinction lies in the type of damage.
傷つける means 'to hurt' or 'to wound' (physically or emotionally) or 'to damage' in a way that causes a scratch, cut, or injury. 汚す refers to making something dirty or staining it, not necessarily causing a physical wound.
彼の言葉は私を傷つけた。 His words hurt me.
Tips
Basic Meaning of 汚す
The most common meaning of 汚す (よごす - yogosu) is to make something dirty or to stain something. Think of it as directly causing something to become unclean.
Transitive Verb
汚す is a transitive verb. This means it always takes a direct object (the thing being dirtied or stained). You are actively doing the 'dirtying' to something else.
Common Usage Example 1
Imagine spilling coffee. You would say, 「コーヒーで服を汚してしまった。」 (Kōhī de fuku o yogoshite shimatta.) - I dirtied/stained my clothes with coffee.
Common Usage Example 2
If a child plays in the mud, 「子供が服を汚した。」 (Kodomo ga fuku o yogoshita.) - The child dirtied their clothes.
Distinguish from 汚れる
Don't confuse 汚す (よごす - transitive) with 汚れる (よごれる - yogoreru). 汚れる means 'to become dirty' (intransitive). The thing itself becomes dirty without someone actively doing it. For example, 「服が汚れた。」 (Fuku ga yogoreta.) - My clothes got dirty.

When using 汚す, the object being dirtied will almost always be followed by the particle を (o). For example, 「手を汚す」 (te o yogosu - to dirty one's hands).

Beyond physical dirt, 汚す can also be used figuratively to mean to sully someone's reputation or bring shame upon something. This is a more advanced usage but good to be aware of.

The past tense of 汚す is 汚した (yogoshita). For example, 「部屋を汚した。」 (Heya o yogoshita.) - I dirtied the room.
Verb Conjugation: Te-form
The te-form of 汚す is 汚して (yogoshite). You can use this for connecting clauses or making requests. For example, 「手を汚してごめんなさい。」 (Te o yogoshite gomennasai.) - Sorry for dirtying your hands.
