The English suffix -nik is of Slavic origin. It approximately corresponds to the suffix "-er" and nearly always denotes an agent noun (that is, it describes a person related to the thing, state, habit, or action described by the word to which the suffix is attached).[1] In the cases where a native English language coinage may occur, the "-nik"-word often bears an ironic connotation,[2] as in the case of the terms coined for the failed rocket launch of the U.S. satellite rival to Sputnik, such as kaputnik, dudnik and flopnik among others.[3]
