Dass (that) is one of the most common subordinating conjunctions in German. Like weil, it sends the conjugated verb to the end of the clause. It is used after verbs of thinking, saying, knowing, wanting and feeling.

Word order with dass

The verb moves from position 2 in the main clause to the very end of the dass clause:

Main clause dass clause
Ich weiß es. Ich weiß, dass es morgen schneien wird.
Er sagt es. Er sagt, dass er keine Zeit hat.
Sie denkt es. Sie denkt, dass heute schon Freitag ist.

Comma rule: always place a comma before dass.

Spelling: dass (conjunction, "that") is always written with double-s. Do not confuse it with das (article/pronoun).
