This paper examines the morpho-syntax of certain pronouns in Alemannic German, spoken in and around Switzerland. Specifically, this work discusses a type of pronoun, termed R-pronoun in the Germanic linguistics literature. Unlike typical nominal elements in German, R-pronouns precede prepositions, and for many speakers in colloquial "standard" (non-Alemannic) German they can also be extracted from PP. In contrast, in Alemannic use of an R-pronoun in PP or extraction of it from PP requires the inclusion of another morpheme in the PP: "de." As the paper will show, in isolation this morpheme is an R-pronoun meaning "it," though it does not have any semantic contribution in the examples under consideration. This project argues that the redundant "de" in such examples can be understood as doubling, via the spell-out of a trace of movement within the prepositional phrase. The paper also provides an explicit account of this doubling using Distributed Morphology along with a copy theory of movement.
