I'm asking this question because I'm currently trying to learn about Super Symmetry but I'm having trouble understanding the concept of superspace and supermanifold.
I read that in superspaces you have 2 Grassmann numbers for each coordinate.

Could anyone explain to me what these Grassmann numbers are?

And then, what's the difference between a regular manifold and a supermanifold?
