For a comprehensive and correct description of the variable, additional features beyond the variable's "type" are required. Each variable has its own unique data type and set of characteristics. Provide a concrete illustration of how this concept may be used to characterize any given variable.

In order for a variable to be correctly defined, it is necessary, in addition, to provide an explanation of its other properties. According to a definition that is more technical, each variable is specified by a data type in addition to other qualities. Describe the general concept that underlies our ability to characterise the features of any given variable.

One must explain a variable's other traits before explaining it. Each variable has a data type and other properties. Explain the basic concept that allows variable qualities to be characterised.

Variable definitions need not just a name, but also the variable's "type" and "additional attributes." The data types of all variables are arbitrary. Clarifying the idea allows us to better define future variables.
