Coordinate ellipsis and information structure

Departing from Rooth's focus interpretation theory the article discusses two types of (German) ellipsis phenomena: direct alternative and implicit alternative coordinative ellipsis. For the first type, which includes Stripping, Gapping, ATB, and RNR, it is characteristic that the semantic value of either conjunct instantiates the context variable of the respective focus operator in the other. For German Polarity ellipsis and Sluicing, which constitute the other type, it is characteristic that the semantic value, which instantiates the variable given by the focus operator in the second conjunct, must be derived from the semantic value of the first conjunct and that the second conjunct always hosts an alternative set inducing item which demands new information focus in the first conjunct.
