The Cognitive Metonymic Motivation ofthe English There be Existential Construction

The There be existential construction is an iconic English sentence pattern, which establishes a spatial cognitive framework for various nouns through the expletive subjectthereand a focus-final structure. So how is such a construction generated? Based on Grammatical Metonymy Theory, this paper proposes that the cognitive motivation of the English existential construction is the core metonymic operation of PLACE-FOR-EXISTENCE, while abstract nouns additionally require the secondary metonymy ENTITY-FOR-STATE to achieve reification. To validate this model, this study employs a corpus-based approach combined with diachronic analysis and contrastive study to analyze 4,000+ instances of the construction extracted from the COCA, COHA, and OED corpora, which indicates that: (1) Concrete nouns, by virtue of their inherent spatial entity status, predominantly enter the construction directly in non-definite forms; (2) Abstract nouns rely on multiple reification means to achieve boundedness; (3) The grammaticalization ofthereis essentially spatial metonymy; (4) A Chinese-English contrast reveals that English adjusts cognitive salience through highly grammaticalized means, whereas Chinese relies more on lexical means and word order to directly present a scene. This study, combining previous research evidence and empirical studies, has firstly proposed a two-tier metonymy model to explain the cognitive motivation of English existential construction.
