Dialects and word variations are fascinating, and statistics researcher Joshua Katz of NC State University has brought them to life in colorful maps — don’t worry, there’s nothing dry about his analysis. He charts where people say “pop” or “soda,” for example, and their answers to more than a hundred other questions on word choices and vowel sounds, using the data from a University of Cambridge study. Not surprisingly, there are a number of food questions on the list. Do you say “frosting” or “icing”? What do you call the long sandwich with cold cuts and lettuce? Check out the full list of questions here, and be prepared to get lost in the colorful maps — it’s interesting to see how words and expressions vary across the country.
