What is a reader doing when they delineate an argument

When a reader delineates an argument, they are breaking it down into its constituent parts and identifying the various elements and components that make up the argument. This process involves analyzing and understanding the structure, logic, and reasoning behind the argument, as well as evaluating the effectiveness and coherence of its claims, evidence, and support. Delineating an argument helps the reader to comprehend and engage with the argument more critically and allows for a thorough assessment of its strengths and weaknesses.
