This document discusses the use of grammatical signals to connect ideas and develop patterns of thought in writing. It focuses on the general-to-particular pattern, where a composition begins with a broad general statement and uses specific details and examples to support and explain the general idea. Grammatical signals like "such as", "for example", "for instance", and "namely" can be used to smoothly connect the general statements to the specific supporting details in a way that maintains coherence and clarity for the reader.
