Nafusi (also spelt Nefusi; in Nafusi: Ažbali / Maziɣ / Mazoɣ or Tanfust) is a Berber language spoken in the Nafusa Mountains (Adrar 'n Infusen), a large area in northwestern Libya. Its primary speakers are the Ibadi communities around Jadu, Nalut (Lalut) and Yafran.[3]
The dialect of Yefren in the east differs somewhat from that of Nalut and Jadu in the west.[4] A number of Old Nafusi phrases appear in Ibadite manuscripts as early as the 12th century.[5][6]
The dialect of Jadu is described in some detail in Beguinot (1931).[7] Motylinski (1898) describes the dialect of Jadu and Nalut as spoken by a student from Yefren.[8]
Nafusi shares several innovations with the Zenati languages, but unlike these other Berber varieties it maintains prefix vowels before open syllables. For example, ufəs "hand" < *afus, rather than Zenati fus. It appears especially closely related to Sokni and Siwi to its east.[9]
