whys and wherefores

1. All the underlying causes and reasons, as in She went into the whys and wherefores of the adoption agency's rules and procedures. This idiom today is a redundancy since why and wherefore mean the same thing. Formerly, however, why indicated the reason for something and wherefore how it came to be. [c. 1600]
