"As soon as I know what it is, I will tell you."
Translation:Sobald ich weiß was es ist, sage ich es dir.
I'm confused that the verb doesn't seem to be in the second position here. There is a conjunction and then a subject, then the verb weiß in the third position. Shouldn't it be "Sobald weiß ich..."
That is on top of the questions everyone else has asked - Why can't the second clause be in future tense, and why is the second "es" necessary?
