a real instance, not abstract
A material object or specific tangible detail, rather than an abstract state, quality, or generality. A concrete description is one that contains specific details that the reader can easily visualize or imagine.
Used to describe a class which implements the behaviour defined by an abstract class. See also: abstract
In philosophy, a concept is considered concrete if it is not abstract: it must be both particular and an individual, and hence occupy both space and time. To say that a physical object is concrete is to say, approximately, that it is a particular individual that is located at a particular place and time.
