Abstract

This study designed a model that can detect syntax errors in Yorùbá simple declarative sentences using pushdown automata (PDA). Information on the structure of Yorùbá simple declarative sentences was gathered and analysed. The structure of these sentences was then modelled using PDA. The PDA model was simulated using Java Formal Languages and Automata Package (JFLAP). T h e behaviour of the model was explored by testing several case scenarios. The model accepted all the cases with the correct syntax and rejected all cases with the incorrect syntax. The PDA model, if implemented, can serve as the logic behind error detection in a Yorùbá grammar checking.
