Imagine the following online dialog.
Question: What is a hyperlink?
Answer: Click on the following,
, or type it into your web browser.
(Thanks to @RegDwigнt♦ for suggesting I use a definition from somewhere other than Google.)
The answer provides an example of a hyperlink that shows the answer to the question of what a hyperlink is.
Is there a specific name for this rhetorical device, where one is shown how to find an answer through an example of the answer?
My first thought for the right word was meta. From wiktionary ...
(informal) Self-referential; structured analogously, but at a higher level.
Suppose you have a genie that grants you three wishes. If you wish for infinite wishes, that is a meta wish.
... but I wonder if there is a more specific rhetorical device that would describe the situation.
Thanks. I'm excited to be part of this site.
Edit: I was originally motivated to ask this question because of a programming example on another forum. @RobbieGoodwin suggested that the question be limited to English language, so I am including a link to a screenshot of that programming example and my explanation. The question is not about programming, it's about a strategy used for answering a question. (As a new user, I appreciate the suggestion.)
