Generally, a singleton is something which exists alone in some way. The word is used in several different areas: * In mathematics, a singleton is a set with unique element. See singleton (mathematics). * In computer programming, a singleton is a common design pattern (computer science). It refers to a Class (computer science) which is meant to be instantiated once, and only once. It is much like a global variable in functional programming, but a "global class-instance" instead. See Singleton pattern. A singleton is also a variable that is only used once in a program, usually indicating a programming mistake. See singleton variable. * In variable-width encoding schemes for computer character sets, a singleton is a character encoded with one unit, as opposed to characters encoded with multiple-unit sequences. * In Unicode, a singleton is a character the decomposition of which consists of a single character (e.g. the "ohm sign" (Ω) is decomposed as the "Greek capital letter omega" (Ω)). * A singleton is a baby that is not a twin or other multiple birth. * In the wake of the popularity of the novel and movie Bridget Jones's Diary, the word has also become popular as a (self-)description of individuals without romantic partners, particularly applied to 20/30-something females. There is an undertone to this use of ignoring societal pressures towards partnerships. * In trick-taking games where suit is important, such as contract bridge and Hearts, if a hand contains only one card of a particular suit, that card is called a singleton. Certain bidding systems (notably Acol) add notional value to the hand for a short suit of this type since it exposes the possibility of trumping. Similarly, holding a "singleton Queen" (of Spades) in Hearts is a very disadvantageous position. * In Whisky singleton describes the last cask or charge of a Whisky. * In espionage a singleton is an an intelligence officer who works alone, in that he has no network. * In science-fiction stories involving multiple parallel realities, a singleton is a person, place, or thing that exists in only one reality, regardless of how alike said realities might be otherwise. This is often used as a rationale for travel between those worlds. * ''Singleton'' is the title of a short story by Greg Egan ==Places called Singleton== In Australia: * Singleton, New South Wales, New South Wales * Singleton, Western Australia, a suburb of Perth, Western Australia, Western Australia In the United Kingdom: * Singleton, Lancashire, Lancashire * Singleton, West Sussex, West Sussex
