Definition

Let $\mathcal L$ be a formal language (for example, the language of predicate logic $\mathcal L_1$).


A constant symbol is a letter of $\mathcal L$ 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 $\mathcal L$.
