I have some questions when to use "haben" and "sein" when building the temporal form "Das Perfekt" with the following verbs:
- Begegnen
- Heiraten
- Abbrennen
I'm trying to find out why the following sentences are incorrect:
Ich bin im Januar geheiratet. (It should be "Ich habe [...] geheiratet", but why? "Heiraten" is supposed to indicate a "Zustandswechsel", isn't it?)
Wo habt ihr euch zum ersten Mal begegnet? (It should be "Wo seid ihr [...] begegnet", so does "begegnen" indicate a "Ortswechsel" or "Zustandswechsel"?)
Das Haus hat bis auf die Grundmauern abgebrannt. (This one got me a little confused. It should be "Das Haus ist [...] abgebrannt." I understand that there is a "Zustandswechsel"; the house burned down. Ok, but there is an "Akkusativergänzung" --> "auf die Grundmauern", so why do we use "sein" instead of "haben"?)
