flush 30秒で
- Flush primarily means using water to clean a toilet or the act of a person's face turning red from heat or emotion.
- It is commonly used in household contexts, medical descriptions of fever, and technical settings involving level surfaces or plumbing.
- The word can function as a verb, noun, or adjective, making it highly versatile across different CEFR levels and professional fields.
- Common idioms include 'flush with cash' and 'flush out,' which expand its meaning into finance and investigative discovery.
The word flush is a versatile verb that primarily functions in two distinct contexts at the A1 level: hygiene and physical reaction. At its most basic, it refers to the action of cleansing a toilet by releasing a sudden flow of water. This mechanical process is essential for sanitation and is one of the first household verbs a learner encounters. Beyond the bathroom, flush describes a physiological response where a person's face becomes noticeably red or hot. This usually happens due to strong emotions like embarrassment, anger, or excitement, or physical factors like heat and exercise. Understanding these two pillars allows a beginner to navigate both domestic chores and basic emotional descriptions.
- Primary Action
- The act of pulling a handle or pressing a button to send water through a toilet bowl to clean it.
- Physical Response
- A sudden reddening of the skin, particularly the cheeks and forehead, often accompanied by a sensation of heat.
- Mechanical Alignment
- In more advanced contexts, it means to be level or even with another surface, though this is less common at the A1 level.
Don't forget to flush the toilet after you use it.
When we look deeper into the emotional aspect, flushing is an involuntary reaction. You cannot control when your face turns red. It is a biological signal of your internal state. For example, if a teacher praises a student in front of the whole class, the student might flush with pride. Conversely, if someone is caught in a lie, they might flush with shame. This duality makes the word incredibly useful for storytelling and describing human interaction. It bridges the gap between simple physical actions and complex human feelings.
Her face began to flush as she realized everyone was looking at her.
In technical or DIY settings, flush takes on a geometric meaning. If a shelf is flush with the wall, there is no gap between them; they form a single, flat plane. This sense is vital for carpenters and engineers. Furthermore, in medicine, doctors might flush a wound with saline solution to clean it out. This connects back to the original idea of using a flow of liquid to cleanse. Whether it is a toilet, a wound, or a person's cheeks, the core concept involves a sudden movement—either of water or of blood.
The carpenter made sure the door was flush with the frame.
The nurse had to flush the dirt out of the cut on his knee.
He was flush with cash after winning the local lottery.
- Etymology Note
- The word likely comes from a combination of 'flash' and 'gush', suggesting a sudden, powerful movement of liquid.
- Usage Frequency
- It is a high-frequency word in daily life, especially in domestic and social settings.
Using the word flush correctly requires understanding its grammatical patterns. As a verb, it can be transitive (taking an object) or intransitive (no object). When talking about a toilet, it is usually transitive: 'You flush the toilet.' When talking about a person's face, it is often intransitive: 'His face flushed.' Understanding these patterns helps you build natural-sounding sentences. In the transitive sense, the object is the thing being cleaned or the liquid being used. In the intransitive sense, the subject is usually the person or the part of the body turning red.
- Transitive Pattern
- Subject + flush + Object (e.g., 'I flushed the system').
- Intransitive Pattern
- Subject + flush (e.g., 'She flushed when he spoke').
- Prepositional Use
- Often used with 'with' to show the cause: 'flushed with anger'.
The plumber told us to flush the pipes with hot water to clear the clog.
When describing the physical reaction of turning red, flush is often paired with the cause of the emotion. We say someone is 'flushed with success' or 'flushed with excitement.' This adds color and detail to your descriptions. It is more evocative than simply saying someone is 'happy' or 'red.' It implies a physical manifestation of that feeling. In writing, using flush helps create a visual image for the reader, making the character's emotions feel more real and immediate.
After the long run, the athlete's face was deeply flushed.
In phrasal verbs, flush often combines with 'out.' To 'flush something out' means to force it out of a hiding place. This could be literal, like flushing a bird out of a bush, or metaphorical, like flushing out the truth in a difficult conversation. This usage is common in detective stories, nature documentaries, and business negotiations. It suggests a process of discovery through pressure or action. Mastering this phrasal verb will significantly elevate your English from basic to intermediate levels.
The police used dogs to flush out the suspect from the woods.
We need to flush out the bugs in the software before we launch it.
The radiator needs to be flushed every two years to prevent rust.
- Common Collocations
- Flush the toilet, flush with pride, flush out a secret, flush against the wall.
- Tense Forms
- Flush (present), flushed (past), flushing (continuous).
The word flush appears in a surprising variety of environments, from the most mundane to the highly specialized. In a domestic setting, you will hear it most often in the bathroom. Parents teach children to flush the toilet as part of basic hygiene. In public restrooms, you might see signs that say 'Please flush after use.' This is the most universal application of the word. However, if you step into a workshop or a construction site, the meaning shifts. You might hear a contractor say, 'Make sure these two boards are flush.' Here, they are talking about precision and alignment.
- In the Home
- Instructions regarding plumbing, cleaning, and hygiene.
- In Sports and Health
- Describing a player's appearance after a game or a patient's feverish look.
- In Literature
- Used to describe characters' emotional states and physical reactions.
The doctor noticed the patient was flushed and checked for a fever.
In the world of gaming, specifically poker, flush is a critical term. A player might announce, 'I have a flush,' which means they hold five cards of the same suit. This is a powerful hand and often leads to high-stakes excitement. You'll hear this in casinos, home games, and on televised poker tournaments. Similarly, in financial news, you might hear that a company is 'flush with capital.' This means the company has a large amount of money available for investment or expansion. It's a sign of financial health and strength.
He went all-in because he had a king-high flush.
In environmental and engineering contexts, flushing refers to the process of clearing out systems. For example, a city might flush the fire hydrants to ensure they are working and to clear sediment from the water mains. You might see workers in high-visibility vests opening valves and letting water gush into the streets. In environmental science, a 'flushing rate' refers to how quickly the water in a lake or bay is replaced by new water. This is vital for understanding pollution and ecosystem health.
The city will flush the hydrants this Tuesday, so the water might be cloudy.
The lake has a low flushing rate, making it sensitive to runoff.
She was flushed with the thrill of her first stage performance.
- In Business
- 'Flush with cash' or 'flushing out the competition'.
- In Engineering
- Surface alignment and system cleaning.
One of the most frequent errors learners make is confusing flush with 'blush.' While they both involve the face turning red, 'blush' is specifically linked to embarrassment, shame, or modesty. You blush when someone gives you a compliment or when you make a mistake. Flush, however, is a broader term. You can flush because you are hot, because you have a fever, because you are angry, or because you just finished a five-mile run. If you say someone 'blushed' after a marathon, it sounds strange to a native speaker because it implies they were embarrassed by the running.
- Flush vs. Blush
- Use 'blush' for social embarrassment; use 'flush' for heat, anger, or physical exertion.
- Flush vs. Flash
- 'Flash' is a quick burst of light; 'flush' is a flow of water or blood.
- Flush vs. Flesh
- 'Flesh' is the soft substance of the body (skin/muscle); 'flush' is an action or state.
Incorrect: I flashed the toilet. Correct: I flushed the toilet.
Another common mistake involves the preposition used with flush. Learners often struggle with whether to use 'with,' 'from,' or 'at.' The most common and natural preposition is 'with.' You are 'flushed with pride,' 'flushed with anger,' or 'flushed with success.' Using 'by' or 'of' in these contexts usually sounds incorrect. Additionally, when using the phrasal verb 'flush out,' learners sometimes forget the 'out,' which changes the meaning entirely. 'Flushing the suspect' sounds like you are putting them in a toilet, whereas 'flushing out the suspect' means forcing them into the open.
Incorrect: He was flushed of excitement. Correct: He was flushed with excitement.
Finally, learners sometimes over-apply the 'toilet' meaning and feel hesitant to use the word in other contexts because they find it 'dirty' or 'improper.' It is important to realize that flush is a perfectly professional and sophisticated word in engineering, medicine, and literature. Don't be afraid to use it to describe a wall being level or a person being successful. Native speakers do not immediately think of toilets when they hear 'flushed with success.' Context is everything in English, and flush is a prime example of a word whose meaning is defined by its surroundings.
The wall panels must be flush with each other to look professional.
The team was flushed with the victory of their first championship.
Don't flush wipes down the toilet; they clog the pipes.
- Spelling Tip
- Remember: F-L-U-S-H. One 'u', no 'a'.
- Pronunciation Tip
- It rhymes with 'rush', 'brush', and 'crush'.
Exploring synonyms for flush helps you understand its nuances. For the physical reaction of turning red, 'blush' is the closest synonym, but as discussed, it is more specific to embarrassment. 'Glow' is another related word, but it usually implies a healthy, positive radiance rather than the sudden, intense heat of a flush. 'Crimson' or 'redden' can be used as more descriptive verbs in literature. For the action of cleansing with water, 'rinse,' 'wash,' or 'purge' are common alternatives. 'Rinse' is gentler, while 'purge' is much stronger and often used in medical or political contexts.
- Blush
- To turn red specifically from embarrassment or shame.
- Rinse
- To wash lightly with water to remove soap or dirt.
- Level
- A synonym for the adjective sense of 'flush', meaning flat and even.
She blushed when he complimented her dress.
In the context of being 'level,' synonyms include 'even,' 'flat,' 'aligned,' and 'abutting.' In carpentry, you might hear 'true' used to mean perfectly straight and flush. If you are talking about being 'flush with cash,' synonyms include 'wealthy,' 'affluent,' 'loaded' (informal), or 'well-off.' Each of these carries a slightly different tone. 'Loaded' is very casual, while 'affluent' is quite formal. Flush sits somewhere in the middle—it's common in conversation but not overly slangy. It suggests a temporary state of having plenty of money.
The tiles were perfectly even and flush with the floor.
When using 'flush out' to mean finding something, synonyms include 'uncover,' 'reveal,' 'expose,' or 'drive out.' 'Drive out' is the most literal equivalent for flushing game (animals) during a hunt. 'Expose' is better for secrets or lies. 'Uncover' is a neutral term for finding something hidden. By choosing the right synonym, you can make your English more precise. However, flush remains a powerful choice because it combines the idea of movement, liquid, and suddenness into a single syllable.
The investigation aimed to uncover the truth and flush out the corruption.
After the bonus, I'm feeling quite flush this month.
The gardener rinsed the pots before flushing the irrigation system.
- Opposites
- Recede (for water), pale (for skin), uneven (for surfaces), broke (for money).
- Nuance Note
- 'Flush' implies a suddenness that 'wash' or 'clean' does not always have.

ヒント
Using 'With'
Always use 'with' when describing the emotion causing a flush. Say 'flushed with pride' or 'flushed with anger'. This is the most natural prepositional choice. Avoid using 'by' or 'from' in these specific emotional contexts.
Flush vs. Blush
Remember that 'blush' is for embarrassment, while 'flush' is for everything else. If you are hot or angry, use 'flush'. This distinction will make your English sound much more precise. Native speakers notice this difference immediately.
The 'U' Sound
