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 word.

The meaning of “concept” is explored in mainstream cognitive science, metaphysics, and philosophy of mind.
