Questions & Answers about Sollte das Benehmen nicht angemessen sein, gibt es Sanktionen seitens des Internats.
Why does the sentence start with the verb Sollte instead of using Wenn?
Just like in English ("Should the behavior..."), you can form a conditional clause in German by dropping the word wenn (if) and moving the conjugated verb to the very beginning of the sentence. This sounds a bit more formal than a standard wenn clause.
How does seitens work here, and what case does it take?
seitens is a formal preposition meaning "on the part of" or "by." As the lesson covers, it requires the genitive case. That is why the neuter noun das Internat changes to its genitive form, des Internats (with the extra "s" at the end).
Could I use vonseiten instead of seitens in this sentence?
Yes, absolutely. vonseiten des Internats means exactly the same thing. Both are highly formal and are mostly used in written German, legal texts, or official statements like this one about boarding school rules.
Why does the second part of the sentence start with gibt es instead of es gibt?
In German, the conjugated verb must take the second position in a main clause. The entire first half of the sentence (Sollte das Benehmen nicht angemessen sein) counts as the first block of information (position one). Therefore, the verb gibt comes right after the comma to take position two, followed by es.
