What is tet dour in cajun french?
I am going to venture it comes from the French "tête dure", meaning strong head, stubborn.
Cajun French is a mixture of French and the native tongue of the Indians living in Louisiana during the French and Indian war. After the Louisiana Purchase, people in that region still kept the language alive (and Cajun is spoken all over Louisiana). (I have heard that Cajun is such a mixture, that many native French speakers have trouble picking up what is spoken.) --shel
