What It Means
Denki o kesu is your go-to phrase for darkness. It combines denki (electricity or light) with kesu (to extinguish or erase). It is simple, direct, and very common. Think of it as 'erasing the light' from the room. It is one of the first collocations you will learn. It feels natural and is used every single day.
How To Use It
You just need the noun and the verb. Put the particle o in the middle. Use kesu for casual talk with friends. Use keshimasu for polite situations or work. It works for ceiling lights and desk lamps. You can also use it for electronic screens. It is a very versatile 'off' button for your vocabulary.
When To Use It
Use it when you leave a room. Say it before you go to sleep. It is perfect for saving energy at home. Tell your roommates to do it often. Use it at the office when leaving. It is also common in schools and public spaces. If the sun is bright, turn them off!
When NOT To Use It
Do not use it for water faucets. For water, use the verb tomeru instead. Do not use it for closing a laptop lid. It is specifically for things with power switches. Avoid it when talking about 'putting out' a large fire. For big fires, use shouka or hi o kesu. Stick to switches and buttons here.
Cultural Background
Japan loves the concept of Mottainai. This means 'don't be wasteful.' Turning off lights is a national habit. Many offices have 'No Overtime' light-off times. It is a small way to show respect. In summer, 'Setsuden' (saving power) is a huge deal. Turning off one light is seen as a group effort. It shows you care about the environment.
Common Variations
Denki o keshite is a soft command for friends. Denki o keshite kudasai is the polite version. Keshite mo ii? asks for permission to darken the room. Keshitara? suggests turning it off to save money. Keshite oku means turning it off beforehand. You will hear these variations everywhere in daily life.
