The phrase breaks down into 電気 (denki), meaning 'electricity' and the verb 点ける (tsukeru), which means 'to light' or 'to turn on' a source of light or fire.

Did you know?

  • If you use the verb つける (tsukeru), it can also mean 'to apply' or 'to dip' in other contexts. Depending on the kanji used, the word for 'turning on the light' is a homonym for 'dipping a piece of food into sauce'.
  • If you want to say 'turn off the light', you use the verb 消す (kesu), which is also the standard verb used for 'erasing' or 'deleting' something written on paper. The conceptual link is the removal or negation of something present.
  • The verb 点ける (tsukeru) used for turning on lights is the exact same word used to describe lighting a cigarette. This linguistic connection links the modern act of flipping an electric switch to the ancient act of striking a flame.

Examples in context
