Let $\mathcal L_0$ be the language of propositional logic.

Let $\circ$ be a connective of $\mathcal L_0$.

Let $\mathbf W$ be a well-formed formula of $\mathcal L_0$.


The scope of an occurrence of $\circ$ in $\mathbf W$ is the smallest well-formed part of $\mathbf W$ containing this occurrence of $\circ$.
