I came across a site yesterday which should be helpful to my year 11 and 12 students studying Cicero at the moment. It offers an exhaustive glossary of rhetorical terms, and gives examples of how they are used from a variety of classical and modern sources. If you've ever wondered what aposiopesis or paronomasia mean, this is the site for you! Here's a short example:
Repetition of the same sound beginning several words in sequence.
*Let us go forth to lead the land we love. J. F. Kennedy, Inaugural
*Viri validis cum viribus luctant. Ennius
*Veni, vidi, vici. Julius Caesar
