Singleton

A singleton refers to a single, isolated instance or entity, often used in contexts where only one of something is permitted or exists. This can apply to objects in programming, individuals in a group, or unique occurrences. The term emphasizes the lack of a counterpart or the restriction to a solitary existence. Its implication is often of uniqueness, singularity, or the enforced absence of any duplication. In various fields, singletons may be valued for their exclusivity or practicality when a single resource is most efficient.
