When you want to say "to turn off" or "to erase" in Japanese, you'll use the verb けす (kesu). This is a very common verb, so it's good to remember it!
You can use it for things like turning off lights or the TV. For example, でんきを けす means "to turn off the light."
It also means "to erase," like erasing writing from a whiteboard or paper. So, if you say じを けす, it means "to erase letters or characters."
It's a useful word to know in many daily situations.
When you're learning Japanese, you'll often encounter verbs with multiple meanings. The verb けす (kesu) is a great example of this, as it can mean both 'to turn off' and 'to erase.'
Think of it like this: you can けす the lights (turn them off) or you can けす a mistake you made while writing (erase it). Both actions involve making something disappear or cease to function.
You'll commonly use けす when talking about electronic devices, like turning off a TV (テレビをけす) or a computer (パソコンをけす). It's also used for extinguishing a fire (ひをけす) or deleting data (データをけす).
Paying attention to the context will help you understand which meaning of けす is being used. For example, if you're in a room with a light switch, けす likely refers to turning off the light.
When you want to say "to turn off" or "to erase" in Japanese, the verb you're looking for is けす (kesu).
It's a versatile verb that you can use for various situations, such as turning off lights, the TV, or even erasing something written on a whiteboard.
For example, if you want to say "Please turn off the light," you would say "でんきを けしてください" (denki o keshite kudasai).
Or, if you need to erase a mistake, you could say "まちがいを けす" (machigai o kesu).
When using 消す (kesu), it's important to understand the nuance of what you are 'turning off' or 'erasing'. For electronic devices like lights, TVs, or air conditioners, it means to switch them off. For data, such as a file on a computer or writing on a whiteboard, it means to delete or erase it. You can also use it when talking about extinguishing a fire or even making your presence disappear, like 'erasing your footsteps'.
When discussing Japanese vocabulary, it's really useful to look at verbs like けす (kesu). This verb is quite versatile, meaning both "to turn off" and "to erase." Think about how we use it for something like turning off lights (電気をけす - denki o kesu) or erasing a mistake from a whiteboard (間違いをけす - machigai o kesu).
Understanding verbs with multiple meanings, especially common ones, helps a lot with fluency. It's not about memorizing separate entries, but seeing how one core idea can apply to different situations. This efficiency in language is something you'll notice often in Japanese.

§ Common Mistakes with けす (kesu)
Many Japanese learners struggle with the nuances of けす (kesu) because it has multiple meanings that don't always directly translate from English. It's not just about turning things off or erasing; context is key. Here, we'll look at some of the most common errors and how to avoid them.
- Mistake 1: Using けす for 'turning off' electronic devices
- While けす can mean 'to turn off,' it's primarily used for things that emit light, sound, or heat. For general electronic devices, たんをいれる (tān o ireru - to turn on) and たんを切る (tān o kiru - to turn off) or 電源を入れる (denpō o ireru - to turn on power) and 電源を切る (denpō o kiru - to turn off power) are more common. Think about the direct action of stopping the flow of power, rather than just extinguishing something.
テレビの電源を切る。(Terebi no denpō o kiru.) - Turn off the TV.
- Mistake 2: Not understanding the 'erase' context
- When けす means 'to erase,' it refers to removing something written, drawn, or recorded. It's not for physically destroying something or getting rid of trash. For 'throwing away' or 'disposing of,' you'd use 捨てる (suteru).
ホワイトボードの字を消す。(Howaito bōdo no ji o kesu.) - Erase the writing on the whiteboard.
ごみを捨てる。(Gomi o suteru.) - Throw away the trash.
- Mistake 3: Confusing with transitive vs. intransitive verbs
- けす (kesu) is a transitive verb, meaning it needs a direct object (marked by the particle を (o)). The action is performed *on* something. The intransitive counterpart is 消える (kieru), which means 'to disappear' or 'to go out' on its own. Forgetting this distinction leads to incorrect sentence structures.
電気を消してください。(Denki o keshite kudasai.) - Please turn off the light. (You perform the action.)
電気が消えた。(Denki ga kieta.) - The light went out. (The light itself went out.)
Understanding these distinctions will significantly improve your accuracy when using けす. Always consider the specific context and whether the action is being performed by an agent or if something is happening spontaneously.
- Use けす for extinguishing flames, turning off lights/sound.
- Use けす for erasing written text or data.
- Remember it's a transitive verb, requiring an object with を.
- For general electronic devices, consider 切る (kiru) or 閉める (shimeru) for closing.
§ Understanding けす (kesu)
けす (kesu) is a versatile Japanese verb with two main meanings: "to turn off" and "to erase." It's an A2-level word, meaning it's quite common and useful for daily conversations. Let's break down its uses and then look at some similar words.
- Japanese Word
- けす (kesu)
- Meaning 1
- To turn off (lights, electronics, etc.)
電気を消す (denki o kesu).
Turn off the light.
(テレビを)消してください (terebi o keshite kudasai).
Please turn off (the TV).
- Meaning 2
- To erase, to delete, to cross out
字を消す (ji o kesu).
Erase the letters/words.
コンピュータのファイルを消しました (konpyuuta no fairu o keshimashita).
I deleted the computer file.
§ けす (kesu) vs. Alternatives
While けす (kesu) is broadly useful, there are other words you might encounter that have similar meanings. Knowing when to use which will make your Japanese more natural.
けす (kesu): This is your go-to for turning off most electronic devices and lights, and for general erasing (like with a pencil and eraser, or deleting digital files). It implies that something that was 'on' or 'present' is now 'off' or 'gone'.
止める (tomeru): While けす (kesu) is for turning things off, 止める (tomeru) means "to stop" or "to halt." You would use this for stopping a car, stopping a clock, or stopping an action.
車を止める (kuruma o tomeru).
Stop the car.除去する (jokyo suru): This is a more formal way to say "to remove" or "to eliminate." While けす (kesu) can be used for deleting digital data, 除去する (jokyo suru) is often used in a more technical or administrative context, like removing obstacles or deleting accounts.
不要なファイルを除去する (fuyou na fairu o jokyo suru).
Remove unnecessary files.削除する (sakujo suru): This is specifically "to delete," usually referring to data or content. It's more precise than けす (kesu) when talking about digital deletion, especially in a formal setting.
メールを削除する (meeru o sakujo suru).
Delete the email.
§ When to use けす (kesu)
Stick with けす (kesu) for these common situations:
Turning off lights, TVs, radios, air conditioners, heaters, etc.
Erasing something written with a pencil, chalk, or on a whiteboard.
Deleting files or data on a computer or phone in a casual context.
Extinguishing a fire or a cigarette.
タバコの火を消す (tabako no hi o kesu).
Extinguish the cigarette.

neutral혼동하기 쉬운
Many English speakers confuse '消す' (kesu) with 'つける' (tsukeru) due to the similar, but opposite, action of turning something on/off. They might also confuse it with other verbs related to removing or deleting things.
'消す' specifically means to turn off (lights, electricity, etc.) or to erase/delete (data, writing, a fire). It implies making something disappear or cease to function.
電気を消してください。 (Denki o keshite kudasai.) - Please turn off the light. この文字を消す。 (Kono moji o kesu.) - Erase these characters.
Can be confused with '消す' when thinking about removing something like dirt or a stain, as both actions can result in something being gone.
'拭く' means to wipe or to dry. It's about physically removing something from a surface using a cloth or similar object, rather than turning something off or erasing it in a more abstract sense.
テーブルを拭く。 (Tēburu o fuku.) - Wipe the table.
Both '消す' and '削除する' can mean to delete. Learners might struggle to know when to use which.
'削除する' is a more formal and typically stronger verb for 'to delete' or 'to remove,' often used for files, data, or items from a list. '消す' is more general and can apply to a wider range of things from turning off a light to erasing a mark.
ファイルを削除する。 (Fairu o sakujo suru.) - Delete the file.
Some might confuse '消す' with '閉める' because both actions stop something, like closing a window and turning off a light.
'閉める' means to close (a door, window, book, etc.). It's about physically moving something to a closed position, not turning off or erasing.
窓を閉める。 (Mado o shimeru.) - Close the window.
Both '消す' and '止める' can be translated as 'to stop,' leading to confusion.
'止める' means to stop (an action, a car, a flow of water). It implies halting movement or a process. While turning something off ('消す') stops its function, '止める' is more about cessation of motion or activity.
車を止める。 (Kuruma o tomeru.) - Stop the car.
팁
Basic Meaning of Kesu
けす (kesu) has two primary meanings: to turn off (lights, electronics, etc.) and to erase (writing, data, etc.).
Using Kesu for Electronics
When talking about electronics, you'll often hear 「電気をけす」(denki o kesu) for turning off the light, or 「テレビをけす」(terebi o kesu) for turning off the TV.
Using Kesu for Erasing
For erasing, you might use 「字をけす」(ji o kesu) to erase characters or 「ごみをけす」(gomi o kesu) to delete data (literally, 'erase trash').
Transitive Verb
けす is a transitive verb, meaning it needs a direct object. This object is marked by the particle を (o). For example, 「電気をけす」.
Related Verb: Kieru
The intransitive counterpart of けす is きえる (kieru), which means to turn off by itself or to disappear. For example, 「電気がきえる」(denki ga kieru) means the light turns off.
Polite Form: Keshimasu
The polite form of けす is けします (keshimasu). Use this when speaking to people you don't know well or in formal situations. For example, 「テレビをけしますか？」(terebi o keshimasu ka?) means Shall I turn off the TV?
Past Tense: Keshita
The plain past tense of けす is けした (keshita). For example, 「電気をけした」(denki o keshita) means I turned off the light.
Negative Form: Kesanai
The plain negative form is けさない (kesanai). For example, 「電気をけさないでください」(denki o kesanai de kudasai) means Please don't turn off the light.
Don't Confuse with Kieru
Remember the difference between けす (you do it) and きえる (it happens). It's a common point of confusion for learners, so pay attention to whether an action is being performed or if something is happening on its own.
Practice Examples
Try making your own sentences: 「スマホの電源をけす。」(sumaho no den'gen o kesu.) - Turn off the smartphone power. 「ホワイトボードの字をけす。」(howaitobōdo no ji o kesu.) - Erase the writing on the whiteboard.
암기하기
기억법
Imagine you're **kicking a shoe** (kesu sounds a bit like 'kick shoe') to **turn off** a light switch or **erase** a chalk drawing on the ground. The action of kicking something away helps you remember both 'turning off' and 'erasing'.
시각적 연상
Picture a remote control with a giant '消す' button on it. When you press it, the TV immediately turns off, and any writing on a whiteboard in the room also magically gets erased. The character for '消' (kesu) itself looks a bit like something being extinguished or disappearing.
Word Web
챌린지
Try using 'kesu' in two different sentences: one where you're turning something off, and one where you're erasing something. For example, 'I turn off the lights' and 'I erase the whiteboard.' Share your sentences with a study buddy!

자주 묻는 질문
10 질문While both can mean 'to stop,' 消す (kesu) specifically means 'to turn off' (lights, electronics) or 'to erase' (data, writing). 止める (yameru) is more general, meaning 'to stop' an action, a car, or even to quit something. Think of it this way: you 消す a light, but you 止める a car.
Yes, absolutely! You can say 携帯を消す (keitai o kesu) to mean 'to turn off your phone.' It's a very common usage.

Yes, it does. You can say パソコンを消す (pasokon o kesu) for 'to turn off the computer.' Many electronics use 消す when you're powering them down.

Yes, you can. ファイルを消す (fairu o kesu) means 'to delete a file.' It's a natural way to express that action in Japanese.
No, not typically. For water, you would usually use 止める (yameru), like 水を止める (mizu o yameru) 'to turn off the water.' For gas, it's more common to say ガスを止める (gasu o yameru) or sometimes ガス栓を閉める (gasusen o shimeru) 'to close the gas valve'.
The polite form is 消します (keshimasu). This is what you'd use in most formal or polite conversations.
Not directly. 消える (kieru) is the intransitive verb for 'to disappear' or 'to go out.' 消す (kesu) is transitive, meaning someone or something performs the action of turning off or erasing. Think of it as: You 消す the light, and then the light 消える.
A common one is 電気を消す (denki o kesu) 'to turn off the light.' Another is 火を消す (hi o kesu) 'to put out a fire.' These are very practical phrases you'll hear often.
