Do You Say 'Y'all' or 'You Guys'?
In another example of how expansive and diverse the U.S. is, The Atlantic produced an audio map that charts 10 different English language dialects across country. Based on Bert Vaux's 2003 Harvard Dialect Survey, and visualizations by Joshua Katz, reporters called people across the country and asked them to pronounce words such as "pecan," "roly poly," and "bag." The map reflects unique phrases and pronunciations that might give some hints as to migration patterns and cultural differences across the nation.
