Square Number: Also known as

A square number is often referred to as a square.

A square number is also often referred to as a perfect square, but this could cause confusion with the concept of perfect number, so its use is discouraged on $\mathsf{Pr} \infty \mathsf{fWiki}$.

In fact it is prime.mover's opinion that perfect square is so utterly bletheringly pointlessly stupid that he has difficulty wondering whether it's worth carrying on sharing a universe with the utter imbeciles who continue to think it's worthwhile to try and defend its use.

This usage may in fact be regional.
