Language Contact in the Sahara: An overview

I am very happy to announce the publication of my freely accessible overview of Language Contact in the Sahara, written for the Oxford Research Encyclopedia of Linguistics. Apart from being the first introduction to this topic to cover both sides of the Sahara, it encapsulates a good deal of my research program over the past few years, and gives some idea of what remains to be done in this domain. Here's the abstract; if it sounds interesting, go read it!

As might be expected from the difficulty of traversing it, the Sahara Desert has been a fairly effective barrier to direct contact between its two edges; trans-Saharan language contact is limited to the borrowing of non-core vocabulary, minimal from south to north and mostly mediated by education from north to south. Its own inhabitants, however, are necessarily accustomed to travelling desert spaces, and contact between languages within the Sahara has often accordingly had a much greater impact. Several peripheral Arabic varieties of the Sahara retain morphology as well as vocabulary from the languages spoken by their speakers’ ancestors, in particular Berber in the southwest and Beja in the southeast; the same is true of at least one Saharan Hausa variety. The Berber languages of the northern Sahara have in turn been deeply affected by centuries of bilingualism in Arabic, borrowing core vocabulary and some aspects of morphology and syntax. The Northern Songhay languages of the central Sahara have been even more profoundly affected by a history of multilingualism and language shift involving Tuareg, Songhay, Arabic, and other Berber languages, much of which remains to be unraveled. These languages have borrowed so extensively that they retain barely a few hundred core words of Songhay vocabulary; those loans have not only introduced new morphology but in some cases replaced old morphology entirely. In the southeast, the spread of Arabic westward from the Nile Valley has created a spectrum of varieties with varying degrees of local influence; the Saharan ones remain almost entirely undescribed. Much work remains to be done throughout the region, not only on identifying and analyzing contact effects but even simply on describing the languages its inhabitants speak.

A Soninke loan in Songhay

There are a rather large number of words in Songhay, the language of the Niger River valley between Timbuktu and southern Niger, which are almost the same as in Soninke, the language of the semidesert regions around the Mali-Senegal-Mauritania borders well to the west. Since most of the basic vocabulary is very different, these must be considered loanwords. But how do we tell which language coined them and which one borrowed them from the other? In some cases, this can be tricky, but in others it's quite clear-cut.

Three years ago, I discussed a Songhay-Arabic poem including the Timbuktu-area word sete "caravan". This word is well-attested elsewhere in Songhay, from eastern Mali to northern Benin (though not in the Sahara proper):

• Gao šeta "(camels) go on caravan", šetete "go in single file" (Heath)
• Hombori sèt-ò "convoy, caravan", sétt-ó "pack of horses" (Heath)
• Kaado sété "village delegation sent to seek food in times of famine" (Ducroz and Charles)
• Zarma sátá "group, troupe, team" (White and Kaba)
• Kandi sété "row" (Heath)

The root is also found in Fulani, eg Gambian Fula sete "caravan" (Gamble), Pular seteejo "traveller, caravaneer", setagol "go on a trip" (Bah), and Heath glosses it as a Fulani loan in his Hombori Songhay dictionary. In neither language, however, does it have an obvious derivation from some shorter or more basic form. For that, we need to turn to a third language - Soninke.

In Soninke, setú is the normal word for "to ride", glossed by Diagana "to be on top, to ride, to perch". By applying the productive morphological process C1V1C2V2 > C1V1C2C2V2, normally used to form imperfectives, we get sètté "caravan, cavalcade, group on horseback, riding". This etymology is not possible in Songhay, where "ride" is kaaru, nor in Fulani, where "ride" is maɗɗ- / waɗɗ-. We thus see that this commercially and politically significant word must have been coined within Soninke. That fits some aspects of the known history of the region: the early Soninke kingdom of Ghana played an important role in the development of the trans-Saharan trade, and even after its fall a diaspora of Soninke traders, the so-called Wangara, played an important role in tying the region together economically.
