Today my conversation group had a heated argument about whether it is correct to say "Ich (or er, sie etc.) wurde (in Berlin, etc.) geboren" or "Ich (...) bin (...) geboren". I looked at a few links and none of them gives a definitive answer:
- Some links say that "bin" is the more colloquial version, but both are correct
- Some say that "bin" must be used if the subject is living, otherwise "wurde".
- Some say that "bin" can only be used if the speaker is talking about the place of birth, otherwise wurde should be used (for example, "Ich wurde 1990 geboren" would be the only correct form according to this version.)
Is there a definitive answer?
