Plot: Why is the English spoken by Maine lobstermen so different from thatscene from the broadcast spoken by cowboys in Texas? Does Spanish pose a threat to English as the dominant language in America? And what on earth do yins, wickety wack, ayuh, catty whompus, and stomping it clean mean? Robert MacNeil travels cross-country to answer these questions and examine the dynamic state of American English – a language rich with regional variety, strong global impact and cultural controversy.
