Some linguists, following William J. Samarin, classify it as a Ngbandi-based creole; however, others (like Marcel Diki-Kidiri, Charles H. Morrill) reject that classification and say that changes in Sango structures (both internally and externally) can be explained quite well without a creolization process.
According to the creolization hypothesis, Sango is exceptional in that it is an African- rather than European-based creole [REF].
