What is the dialect of mice and men?
The story takes place in California, USA, during the Great Depression (1930s). Doubtless many of the characters would have spoken with a Californian dialect, perhaps that of the farm workers and laborers. Some may have other accents and dialects, because there were also many itinerant work-seekers in California at that time, men who travelled far and wide looking for work and for ways to earn some money to live.
