This study addresses the relationship between the formation and development of Nigerian English and the phases proposed in Schneider's (2007) Dynamic theory. In the present study, the propositions of the Model with respect to the formation and growth of Nigerian English are examined and evaluated in the perspective of the contact theory of the evolution of postcolonial varieties of English. It draws attention to properties associated with Nigerian English within the conceptualisation of the Model, focussing on the twin conditions of "sociolinguistic conditions" and "linguistic effects" proposed in the Model, indicating areas which need to be updated. The result critiques the theory and suggests new dimensions for future meta-theoretical development.
