The Futur II is used on different occasions.
a) You use Futur II to refer to actions that will take place in the future and that will have been completed in the future. You form sentences with the conjugated form of the auxiliary verb werden (will), the past form of the verb, and the unconjugated form the auxiliary haben (to have) or sein (to be).
| Singular | Plural | |
| 1st person | ich werde(I will) | wir werden(we will) |
| 2nd person | du wirst / Sie werden(you will) | ihr werdet / Sie werden(you will) |
| 3rd person | er/sie/es wird(he/she/it will) | Sie werden(they will) |
