whether or not

In any case

Whether or not introduces alternatives where the outcome doesn't change the result: I'm going whether or not you come with me.

It can also frame a question about which of two possibilities is true: I don't know whether or not she's coming.

In many cases, "or not" is optional—whether she's coming means the same thing—but the fuller phrase adds emphasis or clarity.
