In my talk, I will argue for the importance of distinguishing two levels of discourse linking: conceptual and referential anaphora. As a test case, I use the German indefinite pronoun einer ('one' or 'someone'), which is ambiguous between (among other) a partitive, an elliptic and an independent reading. I will present experimental evidence on how discourse factors influence the interpretation of einer and discuss how the different types of linking relate to general pragmatic constraints such as DOAP (Don't Overlook Anaphoric Possibilities, Williams 1997).
