The earliest work on a Libyan Arabic variety was written by Hans Stumme (1864-1936), a diligent German linguist who studied a number of language varieties in northern Africa. In his Märchen und Gedichte aus der Stadt Tripolis in Nordafrika (Folktales and Poems from the city of Tripoli in North Africa, 1898), he describes the speakers he interviewed for his research and relates an interesting detail.
Arriving in Tripoli in 1897, Stumme was put in touch with a certain Sidi Brahim bin Ali al-Tikbāli, who he describes as a 45-year old inhabitant of the old city and a skilled poet. Sidi Brahim became Stumme’s main interlocutor for his study of the Tripoli dialect and provided the majority of the texts Stumme transcribed in his book (10 khurrafas and 7 poems). A second speaker, whom Stumme praises as a “walking dictionary”, was a 15-year old black Libyan named Mhemmed bin Jum’a Breñgāli. Besides being Stumme’s guide around the city and general explainer-of-things, Mhemmed provided 3 additional poems which Stumme transcribed. A third person, a Tunisian named Hmed al-Susi who apparently lived in Tripoli, helped translate when Stumme’s knowledge of Tunisian Arabic didn’t suffice to be clearly understood by his Tripolitanian interlocutors.
