What does singularity mean?
Singularity most often means the state or condition of being unique, individual, or exceptionally unusual. It can describe a person, place, object, or event that cannot be matched by anything else, although the word sometimes suggests such an extreme rarity that it appears deliberately dramatic. In mathematics, a singularity is a point at which a function or geometric object is not well-defined or undergoes exceptional behavior. In physics and astronomy, the term refers to a region in which a theory predicts unbounded or otherwise extreme values; classical general relativity, for example, predicts a singularity within a black hole. The word derives from Latin singularitas, meaning singleness or uniqueness. Today it is useful both as an elevated synonym for “one of a kind” and as a precise term for the places where established mathematical or physical descriptions fail to remain ordinary.
nounThe state or condition of being single, unique, or exceptionally unusual. In mathematics and physics, it also denotes a point or region where the ordinary rules of a theory break down, become undefined, or predict unbounded values.
- The state or condition of being unique, individual, or exceptionally unusual.
- A point at which a mathematical function or geometric object fails to be well-defined or exhibits exceptional behavior.
- A region described by a physical theory in which one or more quantities, such as density or curvature, become unbounded.
"Her unusual talent was a singularity that no one else in the class shared."
"The island's singularity lies in its being home to a species found nowhere else."
"General relativity predicts a singularity at the center of a black hole."
The standard plural refers to unique individuals, entities, or instances, or to multiple mathematical or physical singularities.
"The model predicted several singularities at the boundaries of the expanding region."
A mathematical singularity is not an ordinary dot on a graph: it is where the graph's usual rules collapse.

Where does singularity come from?
The word entered English during the Middle English period through Old French singularité, which was borrowed from Latin singularitas, meaning “singleness” or “uniqueness.” Latin singularitas derives from singularis, “single, one, or individual,” ultimately associated with the root singus, meaning “one.” The same source produced English words including singular, singularly, and singularize.
How singularity is actually used
In general use, the word often conveys unusualness or distinction and may have a mildly complimentary or dramatic tone. In mathematics, physics, astronomy, and cosmology, it is a technical term whose precise meaning depends on the theoretical framework.
Easily confused with singularity
Singular is an adjective meaning existing as one person or thing, or unusual and remarkable, whereas singularity is the noun naming the state or condition.
