Abstraction is a process by which concepts are derived from the usage and classification of literal ("real" or "concrete") concepts, first principles, or other methods. "An abstraction" is the product of this process?? a concept that acts as a super-categorical noun for all subordinate concepts, and connects any related concepts as a group, field, or category.
