What Divides, and What Unites, Right-Node Raising

We argue, following Barros and Vicente (2011), that right-node raising (RNR) results from either ellipsis or multidominance. Four considerations support this claim. (a) RNR has properties of ellipsis and of multidominance. (b) Where these are combined, the structure results from repeated RNR: a pivot created through ellipsis contains a right-peripheral secondary pivot created through multidominance. (c) In certain circumstances, one or the other derivation is blocked, so that RNR behaves like pure ellipsis or pure multidominance. (d) Linearization of RNR-as-multidominance requires pruning. The same pruning operation delivers RNR-as-ellipsis, which explains why the two derivations must meet the same ordering constraints.
