Negation of non-indicative mood in Hausa, Fulfulde and Kanuri
Negation of non-indicative mood in Hausa, Fulfulde and Kanuri differs from negation of indicative mood in several aspects. For instance, negation markers of non-indicative mood are morphologically different from those of indicative mood and they occupy different positions within the sentence. This results in a clear contrast between negation of indicative and non-indicative TAM paradigms. What becomes apparent is that the typological feature ‘contrast between negation of indicative and non-indicative mood’ is shared by genetically unrelated languages spoken in northern Nigeria. At first glance one could assume that this phenomenon is the result of structural diffusion in the respective contact region. This feature, however, is also shared by many languages of the West African Sahel.
