Navigate the five master lessons
Use these units as an integrated pathway. You can study them in order or revisit a unit when a writing or speaking task reveals a gap.
1. Choose the form by communicative purpose
At C1, verb forms express stance as well as time. Ask whether you are reporting someone else’s claim, imagining an unreal situation, making a polite request, describing an event or emphasising a state/result.
2. Konjunktiv I in indirect speech
Konjunktiv I is often used in journalism, academic reporting and formal summaries to distinguish reported information from the writer’s own assertion. Common forms include er sei, sie habe, er werde and sie könne. If a Konjunktiv-I form is identical to the indicative, Konjunktiv II may be used to keep the distinction visible.
3. Konjunktiv II: unreal, tentative and polite
Konjunktiv II can express counterfactual situations, imagined outcomes, advice and polite distance. Common forms include wäre, hätte, könnte, müsste, dürfte and würde + infinitive. Prefer a conventional form when it is idiomatic; würde is useful when a synthetic form sounds rare or awkward.
4. Tense and reported time
Indirect speech does not require mechanical tense backshift in the English sense. Choose the form that makes the time relation clear. A reported statement about a current situation may use sei; a prior event may use habe/ sei + Partizip II or a suitable past form, depending on register and meaning.
5. Passive voice and alternatives
Vorgangspassiv (werden + Partizip II) foregrounds an action or process. Zustandspassiv (sein + Partizip II) describes a resulting state. Alternatives such as man, sich lassen, sein + zu-infinitive and -bar adjectives can make formal writing less repetitive.
6. Modal verbs and shades of certainty
Modal verbs express ability, obligation, permission, possibility or inference. In reported and formal contexts, they can also convey the speaker’s assessment: Das dürfte stimmen (that is probably correct), Das muss ein Irrtum sein (that must be a mistake). Interpret modal meaning in context.
Guided practice with explained answers
Try each task before opening the suggested answer. More than one answer may be possible when it preserves the intended meaning and fits the context.
Reported speech
Die Leiterin sagt: „Die Ergebnisse sind belastbar.“ Begin with: Die Leiterin sagt, …
Counterfactual past
Wenn wir früher begonnen hätten, … (die Frist einhalten können)
Process or state?
Describe an ongoing review and then the completed result.
Cautious inference
Use dürfte to say that a delay is probably caused by technical problems.
Writing workshop
Write a short formal report summarising three statements from a meeting. Use Konjunktiv I for reported claims, one Konjunktiv-II recommendation, and both process passive and a passive alternative. Make clear which claims are reported and which are your own conclusions.
Self-assessment
- I can explain why the structure fits the meaning.
- I can distinguish it from a similar structure.
- I can correct at least one common error.
- I can use the structure in connected writing or speech.
- I can edit my work for clarity, register and accuracy.
Grammar works best as part of a complete C1 routine.
