Learn Hardcore Danish: Sluk lyset i køkkenet, når du går, så vi sparer strøm. - Turn off the light in the kitchen when you leave, so we save electricity.

Sluk is the imperative form of the verb at slukke, meaning “to turn off.” It is used to give a direct command—in this case, instructing someone to switch off the light.

How do the words lyset and køkkenet function in this sentence?

Both lyset (“the light”) and køkkenet (“the kitchen”) are in their definite forms. In Danish, adding the suffix (like “-et”) creates the definite form, similar to using “the” in English. This specifies exactly which light and which kitchen are being referred to.

What is the meaning of the phrase når du går, and why is the present tense used here?

Når du går translates to “when you go” or “when you leave.” Although it uses the present tense (går), Danish often employs the present tense to denote actions that will happen in the near future or under certain conditions, much like in English when context makes the timing clear.

What does så vi sparer strøm mean, and how does it connect with the rest of the sentence?

Så vi sparer strøm means “so we save electricity” (or “so we conserve energy”). It explains the purpose or benefit of the action in the first part of the sentence, showing that by turning off the light when leaving, energy is saved.

Why are commas used before når du går and så vi sparer strøm?

In Danish punctuation, commas are commonly used to separate clauses to ensure clarity. Here, a comma is placed before når du går to set off the subordinate time clause from the imperative command, and another comma precedes så vi sparer strøm to clearly separate the resulting clause that explains the intended outcome. This structure helps the reader understand the logical flow of the instructions.

Can you break down the overall structure of the sentence?

Certainly. The sentence consists of three key parts:

The imperative command: Sluk lyset i køkkenet (“Turn off the light in the kitchen”).
A subordinate clause: når du går (“when you go” or “when you leave”), which indicates when the action should happen.
A result or purpose clause: så vi sparer strøm (“so we save electricity”), which explains the reason for the action. Together, these parts form a clear instruction that links an action to its positive outcome.
