Questions & Answers about Wir fordern vollständige Kooperation vonseiten der Eltern.
Why do we use der Eltern after vonseiten?
The preposition vonseiten (meaning "on the part of" or "from") requires the genitive case. Since Eltern (parents) is plural, the plural genitive definite article is der.
Could we use seitens instead of vonseiten in this sentence?
Yes, seitens der Eltern means exactly the same thing. Both seitens and vonseiten are formal genitive prepositions used to express who is producing an action, attitude, or statement. Vonseiten is just a slightly longer alternative.
Is it wrong to just say von den Eltern?
No, von den Eltern is grammatically correct and would mean "from the parents". However, vonseiten elevates the register of the sentence. It sounds more official, bureaucratic, or institutional, which perfectly matches the strong, authoritative tone of Wir fordern (We demand).
Why does vollständige end in -e here?
