Do and does use examples?

Inquiring minds want to know: does the utilization of illustrative instances in a discourse truly enhance comprehension and clarity? Are examples merely a decorative flourish, or do they serve a vital role in the construction and delivery of arguments? Are there specific scenarios or contexts where the inclusion of examples becomes paramount, and where their absence might lead to confusion or ambiguity? Does the use of examples vary depending on the audience or the subject matter being discussed? Ultimately, does the practice of incorporating examples into our language and communication serve to strengthen the message, or is it a mere matter of preference?
