extensional
Defined by instances
Extensional describes meaning or definition based on what something actually includes rather than abstract qualities.
In logic and philosophy, an extensional definition lists the members of a category rather than describing characteristics: defining "planet" by naming Mercury, Venus, Earth, etc. is extensional; defining it by orbital properties is intensional.
The extensional meaning of "dog" is all actual dogs that exist.
