電源を入れる
dengen o ireru
To power on in Japanese is 電源を入れる (dengen o ireru).
電源を入れる is used when you want to start the flow of electricity to an electronic device so that it begins to operate, such as a computer, television or various appliances.
What does it mean word for word?
The phrase is composed of 電源 (dengen), meaning 'power source' and 入れる (ireru), meaning 'to put in' or 'to insert'.
How do you pronounce it?
dengen o ireru
Did you know?
- The word 電源 (dengen) combines the characters for 'electricity' and 'source', but the character 源 (gen) also refers to the 'headwaters' or 'spring' of a river.
- If you want to say the power is 'off', you do not use the opposite of 'put in', but rather 電源を切る (dengen o kiru), which means 'to cut the power source'.
- While 電源を入れる is common for electronics, if you are turning on a light, you would say 電気をつける (denki o tsukeru) instead. The verb つける (tsukeru) is used for things that 'attach' or 'fix' a state of being.
