Abstract: Since Persian has some puzzling cases with regard to the past simple stems (i.e the stems Type II), this study focuses on themorphological treatment of the allomorphy of these verbs. This has been a long-standing issue in morphology addressed in
various analyses till now. The one which is going to be described in the current article seems to work approximately wellwithin Optimality Theory. With the evidence of phonological conditioning, the distribution of various morphs appears not tobe entirely morphological in character. This study proposes an Output-Oriented morphology in which morphologicalprocesses are encoded in FIAT constraints, a type of constraint, and interact with the familiar Faithfulness constraints ofOptimality Theory.
Keywords:Keywords: Optimality theory, output-oriented morphology, faithfulness, FIAT constraint.
