Singleton is a word that is used to refer to something that is singular or one-of-a-kind. For example, if you have a group of friends and one person is always single and never in a relationship, that person might be called a singleton. You can also use the word to describe objects that are uniquely designed or created as a single item, like a rare painting or an antique vase. In computer programming, a singleton refers to a design pattern where a class can only be instantiated once. Overall, singleton is used to describe something that is unique or singular in its kind or category.
