German Futur II: How to Express Assumptions and Future Completions

B2 Sophistication: Futur II (Future Perfect)

In Level B2, language is not just about facts; it is about speculation and precision. Futur II is used in two main ways:

1. Future Completion: Describing an action that will be finished at a specific point in the future (e.g., “By next year, I will have finished my degree”).
2. Assumptions about the Past: This is the most common use! It’s when you guess about something that happened (e.g., “He probably lost his keys”).

1. The Formula: Werden + Partizip II + Sein/Haben

To form Futur II, you need three elements. It looks complex, but the word order is very strict:

Example: “Ich werde die Arbeit gemacht haben.” (I will have done the work).

2. Using Futur II for Assumptions (Vermutungen)

This is where you sound like a native. If someone is late, instead of a simple past sentence, you can say:

• “Er wird den Bus verpasst haben.”
  (He probably missed the bus / He must have missed the bus).
• “Sie wird wohl eingeschlafen sein.”
  (She probably fell asleep).

Note: The word “wohl” is often added to emphasize that it is a guess.

3. Using Futur II for Future Completion

Use this when you want to sound very organized about your goals.

• “Bis morgen werde ich den Bericht geschrieben haben.”
  (By tomorrow, I will have written the report).
• “Bis Ende des Jahres wird er Deutsch gelernt haben.”
  (By the end of the year, he will have learned German).

4. Practical Expat Context: Workplace Speculation

Colleague A: “Wo ist der Chef? Er ist nicht im Meeting.”
You (B2 level): “Er wird den Termin wohl vergessen haben.” (He probably forgot the appointment).
Colleague A: “Glaubst du?”
You: “Ja, aber bis heute Abend wird er sich gemeldet haben.” (Yes, but by this evening, he will have checked in/contacted us).

5. Practice Exercises

A. Form a Futur II sentence (Assumption) from these cues:

1. Thomas / die Prüfung / bestehen (haben)
   -> Thomas ________ die Prüfung ________ ________.
2. Sie / nach Hause / gehen (sein)
   -> Sie ________ wohl nach Hause ________ ________.

B. Translate to German (Future Completion):

1. By next week, I will have found a solution. (Bis nächste Woche…)
2. By 2027, he will have moved to Germany. (Bis 2027… umziehen / sein).
