This book focuses on the structural diversity, semantic variability,
case choice, stylistic characteristics and diachronic distribution of
English absolute clauses. The syntactic roles assumed by absolute
clauses in the traditional sense can be categorized into clausal
adjuncts, attendant circumstances and appositives. These three types of
function correspond to the three hypotactic expansions in the relation
system of clause complexes in Systemic Functional Linguistics, i.e.,
elaboration, extension and enhancement. This research, therefore,
redefines absolute clauses in the framework of SFL and proposes four
syntactic types of absolute clauses: absolute paratactic clauses
(elaboration), absolute hypotactic clauses (extension and enhancement),
absolute projected clauses (fact and act) and absolute embedded clauses
(subject). Based on the Brown family corpora, BNC and COHA, this
research finds that different function types of absolute clauses differ
in terms of their stylistic and diachronic distributions, and both
nominative and accusative cases are acceptable.
