In modern Reunion Creole, the traditional syncretism of zot 'you' and zot 'they' has led to the use of bannla (or banna) as the form of the 3rd person plural. It is, however, debatable whether the syncretism is really the reason for this development. In Barat et al. (1977) about two thirds of the examples have zot, one third bannla. I do not believe that zot and bannla are interchangeable. More research is needed.
