This document discusses forming complex sentences. It reviews simple subject-verb-object sentences and how to add descriptions using adjectives, adverbs, and conjunctions. It then introduces complex sentences, which add a dependent clause using BISAWAVE conjunctions (because, if, since, as, when, although/even though, eventually, besides). Examples show how to build sentences from simple to compound to complex. The goal is to use different structures for varying effects and to enhance writing.
