Some who create new words later wish they hadn’t. They experience “coiner’s remorse.” Such penitents include Alan Greenspan (irrational exuberance), Trent Lott (nuclear option), Peter Drucker (profit center), and John Gyakum (bomb cyclone). Coinage regret is felt for a variety of reasons: coiners can develop reservations about their verbal offspring, terms they coined years earlier may no longer reflect their outlook, or the ways others use and misuse it is not to their liking. In that case coinage penitents don’t regret a term they created as much as its usage. As part of the process of semantic change, linguists assume that the meaning of coined words will diversify in ways never intended by their coiner. This is small consolation to those who introduced such terms, however. They’re far more likely to be perturbed than reassured by this inevitable process of definition diffusion.
