In every language there are competing systems to express the same - or sometimes only almost the same. In English there are two possibilities to refer to something:
The man that stands in the corner over there is my brother.
The man, who stands in the corner over there is my brother.
It seems that French does have more than other languages of these competing systems. We will show them in a comparative way and show the differences and similarities. And, if thinking about it, it will not be as difficult as it seems right now.
