Innovating postverbal negation in North Africa


The present study investigates the grammatical origin of the postverbal negator ḇu in Rif Berber (Afroasiatic, Berber; North, Northeast, and Northwest Morocco) and in Moroccan Arabic of Oujda (Afroasiatic, Semitic; Northeast Morocco), the only languages in which it is commonly attested up till now. Based on new data obtained from recent fieldwork in Morocco, the study will demonstrate that this negator is most probably of Berber origin and has been construed out of an existential by system-internal grammaticalization. The study will also provide evidence for quadruple negation marking in Rif Berber, relating to a reduplication of the ḇu-negator. Moreover, it will show how Berber constantly innovates its cyclical negation system, in which, in this case, different Jespersen Cycles and a Negative Existential Cycle are interlaced. Accordingly, the study will prove that ḇu in Moroccan Arabic is an innovation phenomenon induced by contact with Rif Berber and instantiated through the processes of pattern replication and matter borrowing.
