Concept is an abstract idea, a mental symbol, or an image of a thing held in the mind. Unlike perceptions, which are particular images of individual objects, concepts cannot be visualized. Because they are not themselves individual perceptions, concepts are discursive and result from reason.
Concept typically associated with a corresponding representation in and language or symbology, the basic elements of propositions, much the same way a word is the basic semantic element of a sentence. For example, conceptual physics is the study and description of properties and interactions of space, time, matter, and energy in conceptual non-mathematical form with emphasis on logical reasoning in order to derive fundamental laws of nature and obtain conclusions from these laws by a sequence of logical steps. It is a branch of theoretical physics.
A single concept can be expressed by any number of languages. The fact that concepts are in some sense independent of language makes translation possible. Words in various languages have identical meaning, because they express one and the same concept.
Conceptualization is the process of forming the patterns, judgements, concepts and ideas within the field of thought represented by points of consciousness. It is a process of abstraction, data compression, simplification, and summarization (118).
