The Cambridge Dictionary has selected “parasocial” as its word of the year for 2025. This term describes the perceived connection individuals feel with people they have never met, including interactions with artificial intelligence.

Originally introduced in 1956 by sociologists Donald Horton and Richard Wohl, the term “parasocial” was used to explain how television audiences developed relationships with TV personalities, according to a statement by the dictionary.

The concept remains relevant today as social media users increasingly form parasocial bonds with celebrities.

“The evolution of parasocial relationships has transformed the nature of fandom and celebrity culture,” commented a representative from the dictionary. “With the advent of AI, it also reshapes how people engage online.”

She continued, “In today’s digital age, many find themselves developing intense and sometimes unhealthy parasocial relationships with influencers.”

“Such connections can lead individuals to believe they know and trust these figures, fostering a sense of extreme loyalty,” she explained. “However, these relationships are entirely one-sided.”

Cambridge Dictionary also highlighted a number of other words that it said have had a “significant impact” this year.

Among their number is “slop,” defined as “content on the internet that is of very low quality, especially when it is created by artificial intelligence,” as well as “memeify,” or “to turn an event, image, person, etc. into a meme.”

And the dictionary added 6000 new words this year, with notable newbies including “delulu,” “skibidi” and “tradwife.”
