The American Dialect Society, founded in 1889, is dedicated to the study ofthe English language as practiced in North America, and of the other languages or dialects that influence it (or are influenced by it). Its website describes its membership as including "academics and amateurs, professors and students, professionals and dilettantes, teachers and writers, undergraduates and graduates."

Each year since 1990, the group has anointed a Word of the Year to illustrate that "language change is normal, ongoing and entertaining." This is said to be the oldest continuous such effort, and the only one unaffiliated with a dictionary publisher or other commercial enterprise.
