The word "kayoed" is a slang term that originated in the early 20th century in the United States. It comes from the sport of boxing and specifically from the term "knockout" (often abbreviated as "KO").
The word "knockout" itself entered English in the mid-19th century and was originally used in the context of boxing to describe a situation where one boxer successfully landed a punch that rendered the opponent unable to continue fighting.
Over time, "knockout" started to be shortened, and "kayoed" emerged as a colloquial variation, particularly in American English. The addition of the "-ed" ending serves as a past tense verb form, indicating that someone has been knocked out or defeated in a decisive manner.
