Questions & Answers about Engelen står ved døren.
Because Norwegian usually puts the definite article at the end of the noun.
- engel = angel
- engelen = the angel
This is very different from English, where you add the before the noun. In Norwegian, the noun itself changes form.
For the same reason: døren is the definite form, meaning the door.
- dør = door
- døren = the door
So in this sentence, both nouns are definite:
- Engelen = the angel
- døren = the door
In Norwegian, stå often describes a person or thing as being in a standing position or being located upright somewhere.
So:
- Engelen står ved døren = The angel is standing by the door
If you used er, that would simply mean is, without the idea of standing posture.
Compare:
- Engelen er ved døren = The angel is by the door / The angel is at the door
- Engelen står ved døren = The angel is standing by the door
So står adds a more physical, visual sense.
