Well, I suppose calling it a "singularity" means that it has infinite density by definition, but I'm guessing that "correct definition of the word" is not what you were asking. "Finite mass with zero volume" is what "singularity" means, but for reasons related to time dilation, I don't think true singularities exist.
I chose "Not...Defined...".

Well I voted for "not necessary to be defined as singularities"
but I would certainly appreciate some more discussion.
Not sure what comfort time dilation gives to one unfortunate to fall into a black hole. May he not encounter all the nastiness
we may reasonably expect and conclude that it is a true singularity. Please provide some detail.
A black hole singularity is a region of space-time where the gravitational pull is so strong that it causes matter and energy to collapse into an infinitely small and dense point. This point is known as the singularity, and it is surrounded by the event horizon of the black hole.
Black hole singularities are formed when a massive star collapses under its own gravity at the end of its life cycle. As the star's core runs out of fuel, it can no longer generate enough energy to counteract the force of gravity, causing it to collapse and form a singularity.
According to current theories, nothing can escape from a black hole singularity, not even light. The gravitational pull of the singularity is so strong that it traps everything, including light, within the event horizon.
Yes, according to our current understanding of physics, black hole singularities are infinitely dense. This means that all the matter and energy that make up the singularity are compressed into an infinitely small point, with an infinite density and gravitational pull.
Because nothing can escape from a black hole singularity, it is impossible to directly observe or study them. However, scientists can study the effects of black holes on their surroundings and use mathematical models to understand the properties of black hole singularities.
