On the loss of Ergative Displacement in Basque and the role of analogy in the development of morphological paradigms

Finite verbs in Basque agree with subject, direct object and indirect object. Argument agreement is complicated by the phenomenon of Ergative Displacement. In Bermeo ED has been lost. Both dialectological and diachronic evidence show that this has been the final resul of a process whereby forms are replaced one by one, starting with the least commonly used forms. Speakers employ analogies to derive less common forms, without complete morphological analysis
