Consider three examples of jargon that you use with your friends. Then try explaining them in ways that make them understandable to other people.

Open a dictionary at random, and look at one particularly long entry. How many different meanings are listed for the word you found? How do the meanings vary? Can you think of any connotative meanings not listed in the dictionary?

Find a news article that references a relatively complicated study, a piece of legislation, or a reputable survey. Compare the news article with the original item (which you can usually find through a Web link or search). How different is the language presented in each? What choices has the news writer made in deciphering the study, legislation, or survey for a more general audience?
