Learn Hardcore Norwegian: Bevisstheten kommer langsomt tilbake.

Bevissthet means consciousness or awareness. The ending -en makes it definite singular, so bevisstheten literally means the consciousness.

In Norwegian, this definite form is very common in expressions about a person’s physical or mental state, even when English would usually just say consciousness with no article:

Han mistet bevisstheten = He lost consciousness
Bevisstheten kommer tilbake = Consciousness is returning / He is regaining consciousness

So the definite form sounds natural here.

Why is the article attached to the noun instead of being a separate word?

In Norwegian, the definite article is usually added to the end of the noun as a suffix.

So:

en bevissthet = a consciousness / an awareness
bevisstheten = the consciousness

This is a very basic difference from English. Instead of a separate word like the, Norwegian often builds the definiteness into the noun itself.
