Clause combining, or clause linkage, is traditionally analysed on the syntactic, semantic and prosodic (spoken) levels, and the combinations are called complex sentences in many popular grammars. What is widely accepted today is that clause combining or clause linkage should be understood as mechanisms of connecting clauses rather than sentences. Since the clause is the most fundamental grammatical unit, Chapter 5 considers how non-finiteness plays its role in clause combining from the process-relation perspective. Three types of clause relations are proposed: paratactic, circumstantial and participantial. Non-finite clauses act as the bridges in clause combining viewed from the perspective of metaphoric syndrome. Thus, an answer to the third research question (How does non-finiteness function for inter-clausal connectivity?) is provided.
