This document provides an overview of pidgins and creoles. It defines pidgins as contact languages that arise between distinct linguistic groups for communication, featuring reduced grammar and vocabulary. Creoles develop from pidgins when a new generation acquires the contact language as its native tongue, expanding its structure. The document outlines the processes of pidginization and creolization, and notes that creoles may decreolize over time to resemble the standard language. It provides examples of pidgins and creoles, and a model of their life cycle from jargon to creole and possible convergence with the standard form.
