This book sheds new light on Appositive Relative Clauses (ARCs), a
structure that is generally studied from a merely syntactic point of view,
in opposition to Determinative (or Restrictive) Relative Clauses (DRCs). In
this volume, ARCs are examined from a discourse/pragmatic point of view,
independently of DRCs, in order to provide a positive definition of the
structure. After a presentation of the morphosyntactic, semantic and
pragmatic characteristics of ARCs, a taxonomy of their functions in
discourse is established for both written and spoken English based on the
results of a corpus-based investigation. Constraints are then defined
within an information-packaging approach to syntactic structures to show
why speakers choose ARCs over other competing allostructures, i.e.
syntactic structures that fulfill similar discourse functions (e.g. nominal
appositives, independent clauses, adverbials, noun premodifiers,
topicalization). The end result is a deeper understanding of the richness
of ARCs in their natural contexts of use.
