This volume contains essays on ellipsis -- the omission of understood words or grammatical items from a sentence -- and the closely related syntactic phenomena of conjunction and gapping. Ellipsis poses interesting challenges for linguists because speakers are expressing something that is not present in their words. This volume not only addresses the three perspectives resulting from recent research: Chomsky's syntactic Government and Binding approach, the semantic theories, and the processing accounts, but it also examines the cross-linguistic aspects of ellipsis by comparing the possibilities for a given type of elided structure in Japanese, Arabic, Hebrew, and in English. This volume will be of interest to both semanticists and syntacticians.
