In this thesis, the referential properties of Oromo overt argument noun phrasesrnare described. The thesis has four chapters. In the first chapter, introductoryrnissues are discussed. These include a brief description of the language, thernstatement of the problem, the objective, the significance, the methodology, thernscope of the study, theoretical framework, and review of literature.rnIn the second and third chapters, the central objective is dealt with. With regardrnto this, the principles of binding which deal with pronominal reference arerndiscussed. Accordingly, anaphoric pronominals are bound within theirrngoverning categories, in which there is a governor within a c-command domain,rnan accessible subject, and anaphors should be in agreement with theirrnantecedents. Non-anaphoric pronominals are free in such domain. Sincernlanguages behave differently with regard to the way the binding principlesrnoperate, and with regard to the level of linguistic representation at which thernprinciples apply, that is, SS or LF, this study attempts to account for thernsituation in Oromo.rnIn the last chapter, the summary of the whole analyses is presented. The bindingrnprinciples apply to pronominals predominantly at SS. There are, however, cases,rnwhere they apply at LF. Furthermore, there are some movements that take placernfor the binding relationship to hold between bound pronominals and theirrnantecedents.rnviiirnother hand, however, significant number of the comments seems to have metrnthe students' preferences to a certain extent. Based on the finding of thernstudy, some possible recommendations are suggested.
