Proposes a new semantics for English statements beginning with "there," which adopts the generally rejected characterization of them as subject-predicate prepositions in which the subject is a property or description of an individual and the predicate affirms the instantiation of the property of description. Develops the interpretation of the construction in both a property-theoretic semantics and a version of File Change Semantics, and includes a complete syntactical analysis. Defends the new approach as more successfully at handling certain problematic data, capturing similarities between existential and copular sentences, and predicting cross-linguistic variation in the definiteness effect.
