| Variables, philosophy: variables are symbols in statements or logical formulas, in the place of which various, more precise determinations, such as constants or names of objects, can be inserted. In logic, free and bound variables are distinguished. Free variables, which are not bound by a quantifier such as (Ex) or (x), do not form a statement yet but a statement function such as e.g. "Fx" - "Something is F". Numbers or objects are not variable entities. The variability consists in the applicability of more than one possible value. See also free variables, bound variables, constants, individual constants, individual variables, substitution, substitutability, logic, statements, statement function, formulas._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.

Noam Chomsky on Variables - Dictionary of Arguments
Lyons I 266 Constituent Structure Rule/Transformational Rule/Constant/Variable/Chomsky/Lyons: if the formalization of a system requires that the T-rules should be according to the PS-rules (phrase structure rules) (as in N. Chomsky, 1957)(1), a constituent structure rule would have to be reclassified as a T-rule. This is possible because a constant can always be considered as a variable with only one value. This again demonstrates the heterogeneity of the T-rules. >Constants. 1. N.
