Usage Discussion of KUDO
Some commentators hold that since kudos is a singular word it cannot be used as a plural and that the word kudo is impossible. But kudo does exist; it is simply one of the most recent words created by back-formation from another word misunderstood as a plural. Kudos was introduced into English in the 19th century; it was used in contexts where a reader unfamiliar with Greek could not be sure whether it was singular or plural. By the 1920s it began to appear as a plural, and about 25 years later kudo began to appear. It may have begun as a misunderstanding, but then so did cherry and pea.
