I have researched black holes but I can't seem to find the answer. Any help would be appreciated.

A black hole itself is not a singularity, but General Relativity predicts that a singularity exists at the center of a black hole.
As far as I can determine, it's called a singularity because the laws of physics cease to describe what happens there. Curvature of space-time and density of matter become infinite. They are undefined. In mathematics, a singularity is an object that is undefined, or a point in a set where an object is not well-behaved.
