Let $\LL$ be a formal language with alphabet $\AA$.

Let $S$ be a string in $\AA$.

Let $T$ be a string in $\AA$ such that:

$S = S_1 T S_2$

where:

$S_1$ and $S_2$ are strings in $\AA$ (possibly null)

$S_1 T S_2$ is the concatenation of $S_1$, $T$ and $S_2$.

Then $T$ is called a substring of $S$.
