Word usage from a text
In a song it says: Keiner weiß, was hier geschah
Which makes total sense, it's in the past
Later on in the song it says:
Niemand weiß, was hier geschehen
Could someone tell me why it is geschehen and not geschah
It should always be "geschah" or "ist geschehen" in both spoken or written german. You are only allowed to use "geschehen" without the auxiliary verb if you are a 19th century poet - or apparently Rammstein.
PS. why on earth are Rammstein so popular all over the word? I will never understand this.
