Abstract Northern Songhay languages are known for combining Songhay and Tuareg-Berber features. Nicolai (1979) divided these languages into nomadic and sedentary sub-branches, something which Benitez-Torres and Grant (2017) confirmed, bears out very well from a grammatical standpoint. This paper explores some of the interactions between Songhay and Berber vocabulary by looking at suppletion in Tagdal, a nomadic Northern Songhay language. In Tagdal, suppletion occurs when a verb root of Songhay origin is replaced by one of Berber origin whenever a Berber derivational prefix is present. It will be demonstrated that when Tagdal was in its formative period, the prosodic features that came along with the Songhay and Berber portions of the language made it either easier or necessary to keep the two apart. The paper ends with a brief discussion of how Songhay and Berber vocabulary may have interacted during the period when Tagdal and other Northern Songhay languages were still being formed.

塔达尔的补充

摘要北宋加语语言以结合松加语和图阿雷格伯伯语的特征而闻名。Nicolai（1979）将这些语言分为游牧和久坐的子分支，贝尼特斯-托雷斯和格兰特（Benitez-Torres and Grant，2017）证实了这一点，从语法的角度来看，这很好。本文通过考察北宋游牧民族塔达尔语中的补充来探讨宋海和柏柏尔语词汇之间的一些相互作用。在Tagdal中，只要存在Berber派生前缀，当Songhay起源的动词根替换为Berber起源之一时，就会发生补充。可以证明，塔达尔（Tagdal）处于其形成时期时，该语言的Songhay和Berber部分所伴随的韵律特征使其更容易或有必要将两者分开。
