The author argues for the thesis that pronominal clitics, pronouns, and pronominal affixes are allomorphs of one another, derived from lexical storage of individual grammatical features, e.g., person number, and gender, which are then "spelled-out" as pronouns, affixes, or clitics, depending on how they are stacked, as well as how they are inserted. This study thus crucially assumes a separationist theory of morphology, wehre phonological realization and lexical insertion are separate steps.
