What is "decreolization"

n. The process of decreolize.

Decreolization is a phenomenon whereby over time a creole language reconverges with one of the standard languages from which it originally derived. First proposed by Keith Whinnom at the 1968 Mona conference, the concept has come under fire in recent years from such linguists as Bickerton and Rickford since at its inception it sought to overturn long-held elements of the theory of creole continua.
