Force mismatch in clausal ellipsis

Abstract Recent studies reveal that the values of finiteness, tense, modality and polarity in a clause elided under sluicing may be distinct from their correlates in the antecedent clause. Focusing on CP ellipsis in Hebrew (an instance of Argument Ellipsis), we first demonstrate that it is distinct from both Null Complement Anaphora and (null) pronominalization, and then show that the values of force (declarative, imperative, interrogative) can be distinct between the antecedent and the missing clause as well. Possible mismatches are bidirectional, ruling out “subset” theories of identity in ellipsis and challenging certain accounts of the semantics of polar questions. Implications for the general theory of ellipsis are discussed and evaluated.
