Jebli (Jebelia) is a pre-Hilalian Arabic dialect spoken in the mountains of northwestern Morocco. The historical development of this Moroccan dialect is unclear. The word jebli means "of/from the mountain". It is mainly spoken in the western and southern Rif by tribes of Sherifian, Berber and Morisco descent over the past ten centuries. Jebli is heavily influenced by Berber; the grammar of Jebli is almost Berber while most of the words are Arabic. The vocabulary is highly influenced by Spanish.
