Cajun French
Cajun French (French: français cadien/français cadjin) (commonly called Louisiana Regional French, and related to but distinct from the historical Colonial, or Plantation Society, French) is a variety of the French language spoken primarily in Louisiana, specifically in the southern parishes. The Cajuns assimilated the Colonial Louisiana French dialect, but many mistakenly label it Cajun French. Significant populations of Louisianians—descended from European, African, and Native American ancestors—continue to speak these varieties of French. Parishes where these dialects are still found include, but are not limited to, Acadia, Assumption, Avoyelles, Cameron, Iberia, Lafayette, Lafourche, St. Martin, St. Mary, Terrebonne, Pointe Coupée, Vermillion, and other parishes of southern Louisiana.
Cajun French is derived from the original French spoken by French soldiers and settlers in Louisiana before the arrival of the Acadians. The language incorporates words of African, Spanish, Native American and English origin, unknown in Acadian French. Areas of the state that have almost no population of Acadian origin, such as the parishes of Avoyelles, Evangeline and St. Landry, speak a French that is to some degree mutually comprehensible with the French spoken in areas where the population is heavily of Acadian origin.
