How do I use "pertinent illustration" in a sentence?
You can use it to introduce a supporting case, such as: "The recent market crash provides a "pertinent illustration" of the risks involved in speculative trading."
What is the difference between "pertinent illustration" and a "relevant example"?
While both are similar, "pertinent illustration" sounds more formal and often implies that the example 'illustrates' or sheds light on a complex concept rather than just being a simple data point.
