vers - turned
The word version comes from the Latin root "vers" which means turned. Different versions of a story can often take a different "turn" in the plot or characters. For example, the story of the Three Little Pigs makes the big bad wolf out to be the antagonist. However, in the wolf's version of the story, the wolf just wanted some sugar and had a nasty cold. His sneezing is what knocked over the houses when he went to ask for some sugar. These are two very different versions of the same story. They each have different turns in them.
