Pity the poor speaker. 

All that he or she has to work with during their  speech is words. It is their challenge to find a way to draw their  audience into their speech and make them experience what they have  experienced only using words. In order to make this happen, we need to  find a way to paint a “verbal picture” with the words that we use. We  want our words to create a mental image in the mind of each member of  our audience. 

Just exactly how can we go about making this happen?
