(Wall Street Journal) Building on linguistic data from Dr. Bert Vaux of Cambridge University, North Carolina State University graduate student Joshua Katz has highlighted key differences in American dialects. These maps show the differences.
Soda vs. pop: Coastal residents are more likely to use the word ‘soda’ (in red), while residents of the upper Midwest tend to use the word ‘pop’ (blue). ‘Coke’ (in green) serves as a stand-in for any sweetened, carbonated beverage in some Southern states.
Crawfish vs. crayfish: In the South—particularly in Louisiana, the southeastern part of Texas and in lower Mississippi—and in various parts of the U.S., the crustaceans that resemble lobsters are often called crawfish (in red).
Traffic circle vs. roundabout: Residents of the East Coast, some southerners and a few West Coast residents prefer ‘traffic circle’ (in red). ‘Roundabout’ (blue) is more popular to the west. ‘Rotary’ (yellow) is popular in New England.
