German Conjunctions weil and dass

The conjunctions weil (because) and dass (that) are two of the most frequently used subordinating conjunctions in German. Both introduce subordinate clauses, which means they initiate a shift in word order: the conjugated verb must be placed at the absolute end of the clause. A comma is strictly required to separate the main clause from the subordinate clause introduced by weil or dass.

When building sentences with these conjunctions, the clause structure follows the pattern: Subject + other elements + Conjugated Verb. If there is an auxiliary or modal verb in the clause, it sits at the very end, following any past participles or infinitives (e.g., ...dass er kommen will). In conversational spoken German, you may occasionally hear speakers use weil with main clause V2 order, but this is considered grammatically incorrect in standard written German.

A typical error is forgetting the verb kick, keeping the verb in the second position (e.g., saying Ich glaube, dass er ist nett instead of Ich glaube, dass er nett ist). Another mistake is omitting the comma before weil or dass, which violates German punctuation rules. Be careful to place negations like nicht before the elements they negate, but always keep the verb at the very end.
