Questions & Answers about Angenommen, dass viele kommen, bestuhlen wir den Saal.

What does angenommen mean here?

Here angenommen means something like assuming, suppose, or let’s assume.

It introduces a condition or hypothesis:

• Angenommen, ... = Assuming that ...
• Angenommen, viele kommen, ... = Suppose many people come ...

So it is not being used here as a normal past participle meaning accepted. It functions more like a discourse marker that sets up an assumption.

Why is there dass after angenommen?

Dass introduces a content clause: that many are coming.

However, in this sentence, many learners will notice that Angenommen, dass viele kommen, ... sounds a bit less natural than the more usual:

• Angenommen, viele kommen, bestuhlen wir den Saal.

So:

• with dass: understandable, but less idiomatic here
• without dass: more common after angenommen

A native speaker would very often prefer the version without dass.

Why is kommen at the end of the first clause?
