Abstraction is a process where general rules and concepts are derived from the use and classifying of specific examples, literal (real or concrete) signifiers, first principles, or other methods. "An abstraction" is the outcome of this process — a concept that acts as a common noun for all subordinate concepts and connects any related ...
In software engineering and computer science, abstraction is the process of generalizing concrete details, [1] such as attributes, away from the study of objects and systems to focus attention on details of greater importance. [2]
Abstraction in mathematics is the process of extracting the underlying structures, patterns or properties of a mathematical concept, removing any dependence on real world objects with which it might originally have been connected, and generalizing it so that it has wider applications or matching among other abstract descriptions of equivalent phenomena.
These devices, by definition, do not apply literally and thus exclude any fallacious conclusion that the formal reification is real. For example, the metaphor known as the pathetic fallacy, "the sea was angry" reifies anger, but does not imply that anger is a concrete substance, or that water is sentient. The distinction is that a fallacy ...

An example of a mental construct is the idea of class, or the distinguishing of two groups based on their income, culture, power, or some other defining characteristic(s). An operational definition specifies concrete, replicable procedures that reliably produce a differentiated, measurable outcome. Similarly, concepts can remain abstract or can ...
The term abstraction has a number of uses in the field of linguistics. It can denote a process (also called object abstraction) in the development of language, whereby terms become used for concepts further removed from the objects to which they were originally attached. It can also denote a process applied by linguists themselves, whereby ...
In philosophy and the arts, a fundamental distinction exists between abstract and concrete entities. While there is no universally accepted definition, common examples illustrate the difference: numbers, sets, and ideas are typically classified as abstract objects, whereas plants, dogs, and planets are considered concrete objects.
