When I lived in Lafayette a bit over 30 years ago there was an effort to create a Cajun French dictionary, since it had become a spoken as opposed to written language. My wife had a bunch of Cajun women working for her. She had trouble understanding them given her high school and college French. At that time there were distinct dialects of Cajun French even among the towns fairly close together, and the women from Lafayette made fun of the accent of people from Abbeville.
