A descriptive variable is a relation between a set of beings to be described and a set of descriptive values with the property that each being is related to exactly one descriptive value.

A descriptive variable can be noted *X*: *Ω* -> M(*X*), where *Ω* and M(*X*) denote the set of beings to be described, and the set of possible descriptive values, respectively.
