whatness
Core identifying nature
Whatness is the essential nature or defining quality of something—what makes it the thing it is rather than something else.
The term belongs to philosophy, translating the Latin *quidditas*: The whatness of a chair includes its function as something to sit on.
It asks not whether something exists, but what it fundamentally is.
