Meh, Eh?

A reader writes:

Writing as one of your readers from Cajun country (Lafayette, Louisiana) I can tell you that people of French Canadian descent have been using the word "mais" which they pronounce "meh" in exactly the same manner as you and others have used the word "meh." Of course, in French the word "mais" means "but." Cajuns casually throw the word around in all sorts of ways, sometimes all by itself to mean nothing at all. "Mais!"

Just thought you'd like to know that some people in this country have been using that word for centuries.
