According to wikipedia the term concept is defined as such:

"A concept is a cognitive unit of meaning—an abstract idea or a mental symbol sometimes defined as a "unit of knowledge," built from other units which act as a concept's characteristics. A concept is typically associated with a corresponding representation in a language or symbology such as a single meaning of a term. The meaning of "concept" is explored in mainstream information science, cognitive science, metaphysics, and philosophy of mind. The term "concept" is traced back to 1554–60 (Latin conceptum - "something conceived"), but what is today termed "the classical theory of concepts" is the theory of Aristotle on the definition of terms."
