Since 1990, the American Dialect Society has identified one or more words or expressions as the word of the year. According to the society's website, "Words of the Year are those that reflect the concerns and preoccupations of the year gone by. They need not be new, but they usually are newly prominent."
Words are selected by members of the society, acting "in fun" and not "officially inducting words into the English language." The purpose of the annual event is to illustrate the point that "language change is normal, ongoing, and entertaining."
Here, as determined by members of the American Dialect Society, are the words and expressions that have been recognized as Words of the Year since 1990.
