 \begin{definition}
 	Let $F$ be a field and $p(x) \in F[x]$ a polynomial of degree $n$.
 	Then $p(x)$ has roots $\alpha_1, \dots, \alpha_n$ in an algebraic closure of $F$.
-	The \vocab{splitting field} of $F$ is defined as $F(\alpha_1, \dots, \alpha_n)$.
+	The \vocab{splitting field} of $p(x)$ over $F$ is defined as $F(\alpha_1, \dots, \alpha_n)$.
 \end{definition}
 In other words, the splitting field is the smallest field in which $p(x)$ splits.
