Intension refers to the inherent meaning or conceptual content of a term, expression, or idea. It is often contrasted with "extension," which refers to the set of objects or instances that the term refers to in the real world. In philosophy and linguistics, intension is concerned with the qualities and attributes that define a concept. For example, the intension of the term "dog" would include characteristics like being a domesticated mammal, typically having four legs, and being a known species.
