Definition:Constant Symbol

Definition
Let $\LL$ be a formal language (for example, the language of predicate logic $\LL_1$).

A constant symbol is a letter of $\LL$ used to describe a constant.

The name constant symbol is a gesture to the reader to make clear what such a symbol should (intuitively) represent in the formal language $\LL$.
