Just wondering if nachdem is the only preposition which induces a change in the tenses:
Nachdem wir gegessen hatten, bin ich nach Hause gefahren.
As far as I know, here it wouldn't be correct to keep both sentences with the same grammatical tense:
Nachdem wir gegessen haben, bin ich nach Hause gefahren. ← falsch(?)
- Is this true?
- Is nachdem the only preposition which needs this consecutio temporum?
For instance, the original sentence would be quite the same as:
Bevor ich nach Hause gefahren bin, haben wir gegessen.
Shouldn't I use here Plusquamperfekt
in the subordinate clausule for sake of consistency? Or is this last sentence wrong?
nachdem
-clause, then present if of course not possible, but present perfect is: "Nachdem ich gegessen habe, werde ich schlafen." – Toscho Nov 6 '13 at 18:34
