What does it mean to illustrate a point in writing?

To illustrate a point in writing means to clarify or explain an idea by using examples, images, or descriptions that make the concept more understandable for the reader. When a writer illustrates a point, they provide concrete instances or visual aids that help to clarify complex ideas, making them more relatable and easier to digest. This technique enhances the reader's comprehension and retention of the material by connecting abstract concepts to familiar examples or situations, effectively bridging the gap between the writer's thoughts and the reader's understanding.
