U.S. dialects are continuously evolving, with adolescent girls identified as key drivers of linguistic change, according to Betsy Sneller, an associate professor of linguistics at Michigan State University. The Telsur Project, pioneered by the University of Pennsylvania in the 1990s, surveyed over 700 individuals from major U.S. urban areas to examine pronunciation, word choices, and syntax, identifying eight major dialects across the country.

"Consistently across every dialect that we have ever studied, it is adolescent girls who are half a generation to a full generation ahead of the curve," Sneller said. "What they're doing is where language is gonna go." She added, "If you really want to get a snapshot of the future of a language, record a 20-year-old woman talking crap about somebody." Sneller also noted that language is central to personal identity. "Your language is so central to your identity," she said. She described how a New York English phrase evokes an image of toughness, a perception often reinforced in media portrayals. "So if you hear somebody speaking in New York English, you know, 'Hey, give me a coffee,' immediately in your mind, you're thinking of like rough and tumble, I'm tough," Sneller said. "That's the vibe of a New York accent, and you see this in media, like when movies want to portray somebody as being tough, they use either a New York accent or a Boston accent."

Salikoko Mufwene, a linguistics professor at the University of Chicago, explained that African American English shares origins with Southern English but developed variations based on the timing of segregation. He noted the Gullah Geechee language, which emerged in coastal South Carolina and Georgia among enslaved people who formed a black majority and experienced segregation in the early eighteenth century. In contrast, in areas with tobacco and cotton plantations, enslaved people were generally a minority, and their English had minimal differences from European settlers until segregation under Jim Crow laws. "We are talking here about two centuries of difference in the timing of residential segregation," Mufwene said. He noted that varieties such as German English, Italian English, and Polish English have disappeared in the U.S. "So they maintain African American English because it is part of their cultural identity," Mufwene said. He added that individuals tend to adapt their language to fit the people with whom they interact regularly. "You want to fit with the people that you are interacting regularly with," he said. Many African Americans, particularly those in racially integrated communities, are bicultural and bi-dialectal.

Karen Norris Newsome, who is 74, was born and raised on a farm in Darlington County, South Carolina. "I'm a very proud Southern woman," Newsome said. "I am very hardworking and very strong as magnolias." She expressed concern about changing social dynamics. "I think we're gonna lose the personal touch that I was raised with, the respect I have for my neighbors," she said. "I think you better get out, take a plate of cookies over to them, and meet them, because you never know whenever you may fall in the yard and need them to come help you up, which has happened to me before." Newsome also commented on national sentiment. "I think America is the land of the free, it still is, but I think we don't appreciate it as much as we used to," she said.
