Questions & Answers about An dieser Stelle ist der Weg glatt.
Because an is a two-way preposition in German, and here it describes a location rather than movement.
- movement toward a place → accusative
- location in/at a place → dative
In An dieser Stelle, the meaning is at this spot / at this point, so German uses the dative.
- die Stelle = nominative
- an dieser Stelle = dative
Also, Stelle is a feminine noun, so the form of dieser must match:
- nominative feminine: diese
- dative feminine: dieser
So an dieser Stelle is the correct form.
It is an adverbial phrase of place. It tells you where the path is slippery/smooth.
So the sentence structure is basically:
- An dieser Stelle = at this spot / here
- ist = is
- der Weg = the path
- glatt = slippery/smooth
It answers the question Where is the path glatt?
