Learn Danish: Kan du slukke lyset på badeværelset? - Can you turn off the light in the bathroom?

In Danish, you use the preposition på (on) for rooms that traditionally have a specific utility or function, like the bathroom (badeværelset) and the kitchen (køkkenet). For most other rooms, like the living room (stuen) or the bedroom (soveværelset), you use i (in).

Does slukke only mean to turn off lights?

You can use slukke to talk about turning off anything electrical, like a TV, an oven, or a phone. It originally means "to extinguish," so it is also the word you use for putting out a fire or blowing out a candle. The opposite word, meaning to turn on or light, is tænde.

Why do both lys and badeværelse end with a -t in this sentence?

They are both neuter words, meaning they use et instead of en for "a" or "an". To make them definite (meaning "the light" and "the bathroom"), that article moves to the end of the word. Lys becomes lyset, and since badeværelse already ends in an "e", it just gets a -t at the end to become badeværelset.

Why isn't the verb slukke in the present tense (slukker) here?
