The term 'A Little World' can be summed up as a microcosm, which is a nine-letter word. A microcosm is a small system or community that is seen as an example of a larger system or society. It is often used to describe a situation in which a small group of people or things represent a larger group. For example, a small town could be seen as a microcosm of the larger country in which it is located.
