The larger divisions of Tuareg have names by which they are known to themselves and to their neighbours: these names designate the historical or geographical groupings of tribes. In each group of tribes the existence of nobles and serfs is recognised; there are appropriate terms to describe these social distinctions. The nobles are called Imajeghan;[14] the servile people, Imghad. But no name other than Kel Tagilmus,[15] the “People of the Veil,” exists to describe the society of nobles and serfs alike, irrespective of group or caste. These details will require fuller examination in due course, but it is important to realise immediately that the name Tuareg[16] is unknown in their own language and is only used of them by Arabs and other foreigners. It has, however, been so universally adopted by everyone who has had to do with them or who has written of them that, although not strictly accurate, it would be pedantic not to continue using it. The Tuareg all speak the same language, called Temajegh, which varies only dialectically from group to group. They have a peculiar form of script, known as T’ifinagh, which also is practically identical in all the divisions of the Tuareg, but is apparently not used by other peoples. Lastly, the Tuareg are nomads by instinct and, save where much intermarriage has taken place, of the same racial type. The conquest of foreign elements in war and their assimilation into servile tribes have, in the course of time, led to some modification of physique and a growth of sedentarism in certain areas. As a whole, however, the nation has survived in a fairly pure state which is readily distinguishable. There is, I think, no justification for considering the People of the Veil a large tribal group of Berbers in North Africa; they are a separate race with marked peculiarities, distinct from other sections of the latter, and, as I believe, of a different origin.
