German Dass-Sätze (dass-clauses)

What is a "Dass-Clause"? ("dass–Sätze")

Dass-clauses are subordinate clauses that start with the German Conjunction "dass." Without the dass-clause the main clause doesn´t make sense.

  • dass–clauses are Subordinate Clauses (Nebensätze). The verb is therefore at the end of the sentence.
  • The Subordinate Clause with „dass“ describes a fact or action without which the main clause doesn´t make sense.
  • It stands in place of other complements (grammatically necessary parts of sentences) that are required for the the sentence to make sense.

⇒ The main clause makes no sense without the subordinate clause with „dass“ and often stands in place of an accusative complement. That is why the „dass-clause“ is also called a complement sentence.

Verbs with "Dass-Clauses"

When something is known or believed:

  • Ich weiß, dass du gestern bei Maria warst!“
  • Ich bin mir sicher, dass du das besser kannst.“
  • Ich glaube, dass Mark in mich verliebt ist.“

Also: denken, meinen, vermuten, der Meinung sein, hoffen,…


For thoughts, feelings, opinions:

  • Ich finde, dass ihr mehr Deutsch lernen solltet.“
  • Ich finde es gut, dass ihr deutsches Fernsehen schaut.“
  • Es ist wichtig, dass du jeden Tag Deutsch lernst.“
  • Es tut mir leid, dass ich dich angeschrien habe.“
  • Ich freue mich, dass du die Prüfung bestanden hast.“
  • Ich habe Angst, dass du mich verlässt.“

For indirect speech = repeating what someone else said

  • Er sagt, dass er zu Hause sei.“
  • Sie haben geantwortet, dass sie bei Oma gewesen wären.

Dass-clauses are used when the speaker is relatively sure about what they're saying.

„dass“ or „ob“?

When the speaker isn't sure if it's true or not, „ob“ must be used:

  • Ich habe keine Ahnung, ob ich die Prüfung schaffen werde.“
  • Jan überprüft, ob er noch genug Geld auf dem Konto hat.“

More example of „dass“ and „ob“:

  • Er sagt, dass du gestern bei Oma warst.“ (sure)
  • Er sagt mir nicht, ob du gestern bei Oma warst.“ (not sure)
  • Ich weiß, dass du mich liebst.“ (sure)
  • Ich weiß nicht, ob du mich liebst.“ (unsure)

Word Order

Since they are subordinate clauses, the verb goes at the end:

dass-Sätze / Dass-clauses main clause subordinate clause dass and ob
dass-Satz / Dass-clause subordinate clause main clause dass ob

Summary

  • Dass-clauses / dass-Sätze start with "dass" and are needed for the main clause to make sense.
  • Since they are subordinate clauses, the conjugated verb goes at the end.
  • They are used for expressing feelings / opinions / judgments / thoughts / knowledge, as well as for indirect speech.
  • A dass-clause expresses relative certainty about what the speaker is saying.
    Uncertainty can be expressed with "ob."
