When a pidgin has become the primary language of a speech community, and is acquired by the
children of that speech community as their native language, it is said to have become a Creole. The
structure of the original pidgin is expanded to enable it to fulfill its new functions. The vocabulary is
vastly enriched, and new syntactic-semantic concepts developed. Notable examples of Creole are the English-based Creole of Jamaica, and the French-based Creole of Haiti.
