Divisible, Separable
noun
When it's possible to separate something, it's divisible. Just imagine separating things into parts. It's possible. So, if that's possible, it's divisible. Now think of something that's nothing (i.e. "no candy bars"). That is not possible to separate into parts. That is not divisible.
