Specificational and Predicative Clauses : A Functional-Cognitive Account

In studies of copular clauses, the relation between specificational and predicative clauses has been a contentious issue. While most studies agree on the analysis of predicative clauses, specificational clauses have sparked much debate. A key concern is how specificational clauses with indefinite ‘variable’ NP (e.g. "A popular holiday go-to is Rome") compare to, and contrast with, other copular clauses, especially specificational clauses with definite ‘variable’ NP (e.g. "The main can’t-miss in Italy is Rome") and predicative clauses with indefinite predicate nominative (e.g. "Rome is a great city"). This book addresses this concern by offering a functional-structural analysis of these three clause types in terms of their common characteristics and distinguishing features. The analysis of the clauses’ structure and meaning is substantiated by evidence from corpus research which probes into various aspects of their actual usage (e.g. information structure and prosody, discourse-embedding). In doing so, the book offers an empirical basis for testing existing assumptions about predicative and specificational clauses, while also providing new insights into the interaction between the grammar and discourse usage of copular clauses.
