1. Constructing Complex Sentences
Complex sentences result when other more sophisticated devices are used to join clauses; this means a subordinate (dependent) clause is joined with a main (or independent) clause.
There are three main ways to join clauses to make complex sentences. By using:
Relative pronouns – that, which, who, whose
Conjunctions (subordinating) – while, because, although, as, when, until, unless, through, by, since, whenever, if, where, before, etc
