Questions & Answers about Er behauptet, dieses Ritual sei gefährlich.
Why does this sentence use sei instead of ist?
sei is the Present Subjunctive (Konjunktiv I) form of sein (to be) for he, she, or it. We use it here for reported speech because we are reporting what he claims (Er behauptet) without confirming if it is actually true. By using sei, you distance yourself from his statement, making it clear that these are his words and not necessarily a fact.
Since this is reported speech, shouldn't the verb sei go at the very end?
It would go at the end if we used the connecting word dass (that), like this: Er behauptet, dass dieses Ritual gefährlich sei. However, German allows you to drop dass in reported speech. When you drop it, the reported clause uses standard main-clause word order, meaning the verb sei stays in the second position right after the subject dieses Ritual.
Is behaupten a common trigger for this kind of grammar?
Yes! behaupten (to claim) is a very common trigger for the Konjunktiv I. Verbs of speaking, thinking, or claiming—like sagen (to say), meinen (to think/reckon), or berichten (to report)—often introduce reported speech. Because a claim implies it might not be a proven fact, using sei is the perfect way to show neutrality.
Could I just use ist instead of sei in everyday conversation?
