Case Theory interacts with Government Theory in its operation and so, cases are assigned to the complements of governors. Case assigners are the governors of their dependent clauses while the case receivers are the governed NPs. So, the purpose of the study is to survey case assignment in Fulfulde generally by identifying and analysing the elements of Fulfulde structures and their relationship in terms of structural case. Unstructured observation was the method used for eliciting data for this study. Adequate and natural data were recorded and analysed sentence by sentence, the way they were uttered by the native speakers. The Theoretical Framework adopted for data analysis by this study is Principle and Parameters Theory. The study discovered that in Government, apart from (V)erbs, (P)repositions and tensed INFL, (N)ouns, (A)djectives and Focus Markers FMs can also govern and assign case to their complements in Fulfulde. The study has proved that in Fulfulde, cases can be assigned either to the left or to the right, depending on the relation.
