Questions & Answers about Du wirst mir sofort gehorchen, denn du bist der Lehrling!
Why use wirst ... gehorchen instead of the normal imperative Gehorche?
Using the Futur I (werden + infinitive) is a way to issue an indisputable, authoritative command. By saying 'You will do this,' it leaves no room for argument or refusal. It sounds much stricter and more dominant than a standard imperative like Gehorche mir sofort.
What role does sofort play in making this a command?
Words like sofort (immediately) or jetzt (now) are strong clues that a Futur I sentence is a command rather than a genuine prediction about the future. Without it, Du wirst mir gehorchen might just mean a factual 'You will obey me (eventually).' Adding sofort locks in the demanding, authoritative tone.
Why is it mir instead of mich?
The verb gehorchen (to obey) always requires a dative object. Even though in English we obey someone directly, in German you are essentially rendering obedience to someone. That is why the dative pronoun mir is used instead of the accusative mich.
Why doesn't the verb bist go to the end of the sentence after denn?
