A singularity originally referred to a single point where (the mathematical description of) a field has infinite strength. That's not really true. The term singularity was almost certainly first used in mathematics. Most physicist don't believe that there are singularities in nature, it's just our incomplete or simplified physical theories that have them in their equations. And in mathematics there are quite a few kinds of singularities, of isolated points that have drastically different behavior than their neighborhood, and diverging to infinity is just one example.
