This marvellous page hyperlinks a range of classical rhetorical terms and explanations,with examples of each. The links on the left are most useful - organising and classifying the approaches to speechifying in a range of well-crossreferenced ways.
An exploration of rhetoric isn't only useful as a way into thinking about discourse structures, sentence structures and semantic tricks – though the terms aren't ones we need to know at A Level – but also a way to think about structuring your own writing and presentations.
