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.

Frequency Effects in Grammar
Holger Diessel and Martin Hilpert
Until recently, theoretical linguists have paid little attention to the frequency of linguistic elements in grammar and grammatical development. It is a standard assumption of (most) grammatical theories that the study of grammar (or competence) must be separated from the study of language use (or performance). However, this view of language has been called into question by various strands of research that have emphasized the importance of frequency for the analysis of linguistic structure. In this research, linguistic structure is often characterized as an emergent phenomenon shaped by general cognitive processes such as analogy, categorization, and automatization, which are crucially influenced by frequency of occurrence.
There are many different ways in which frequency affects the processing and development of linguistic structure. Historical linguists have shown that frequent strings of linguistic elements are prone to undergo phonetic reduction and coalescence, and that frequent expressions and constructions are more resistant to structure mapping and analogical leveling than infrequent ones. Cognitive linguists have argued that the organization of constituent structure and embedding is based on the language users’ experience with linguistic sequences, and that the productivity of grammatical schemas or rules is determined by the combined effect of frequency and similarity. Child language researchers have demonstrated that frequency of occurrence plays an important role in the segmentation of the speech stream and the acquisition of syntactic categories, and that the statistical properties of the ambient language are much more regular than commonly assumed. And finally, psycholinguists have shown that structural ambiguities in sentence processing can often be resolved by lexical and structural frequencies, and that speakers’ choices between alternative constructions in language production are related to their experience with particular linguistic forms and meanings. Taken together, this research suggests that our knowledge of grammar is grounded in experience.
