Claim: Of the three major dialects of the French language in the United States (Louisiana French, Missouri French, and New England French), Louisiana French is traditionally subdivided into Colonial French, Louisiana Creole French, and Cajun French (which linguists would identify as Louisiana Creole).
Evidence: There are three major groups of French dialects that emerged in what is now the United States: Louisiana French, Missouri French, and New England French (essentially a variant of Canadian French). Louisiana French is traditionally divided into three dialects, Colonial French, Louisiana Creole French, and Cajun French. For example, speakers of Louisiana Creole who identify as Cajuns often label their language 'Cajun French', though on linguistic grounds their language would be considered Louisiana Creole.
