Paragraph development by illustration or example involves using specific instances or anecdotes to clarify and support a general statement or idea. Instead of relying on abstract concepts, this method uses concrete examples to make the point more relatable and understandable. By providing vivid details and real-life scenarios, the writer can bring the argument to life and engage the reader's imagination. This technique is particularly effective when explaining complex concepts, demonstrating a pattern, or proving a claim. For instance, in a paragraph about the importance of reading, one could illustrate this point by sharing a personal experience about how reading a particular book changed their perspective or inspired them to pursue a new hobby.
