Questions & Answers about Der Schlitten rutscht über den zugefrorenen Fluss.
How is zugefrorenen formed, and why does it have that -en ending?
It comes from the separable verb zufrieren (to freeze over). The past participle is zugefroren. When we put it in front of the masculine noun Fluss to describe it, it acts just like a normal adjective. Because the phrase is in the accusative case after über, it takes the masculine accusative adjective ending -en.
Why do we use the accusative case (den ... Fluss) after über here?
The word über is a two-way preposition. Because the sled is moving across the river from one side to the other, it indicates a direction or a path being taken. This directed movement requires the accusative case. If you wanted to talk about a fixed location rather than movement across something, a two-way preposition would take the dative case instead.
What does the prefix zu- add to the verb frieren?
The verb frieren means to freeze (either feeling cold or turning to ice). The separable prefix zu- often implies closing or shutting something. Combined, zufrieren means to freeze over or freeze shut, which perfectly describes a river whose surface has been sealed off by a layer of ice.
Can the past participle of any verb be used as an adjective like zugefroren?
