Description

Printed Page 473

When you use description, you use words to paint a mental picture for your listeners, so that they can close their eyes and imagine what you are saying. If you provide sufficient information and detail, your audience may be able to experience vividly what you describe—and through multiple senses. For example, you might decide to use description to help your audience understand one of the following:

Example
Dictionary The meaning of a term as it appears in a dictionary Merriam-Webster’s Collegiate Dictionary, Eleventh Edition, defines obscenity as “something that is obscene”—that is, “disgusting to the senses.”
Expert Comes from a person or an organization that is a credible source of information on your speech’s topic According to Chief Justice Burger of the U.S. Supreme Court in the 1973 case Miller v. California, obscenity is expression that appeals to a “prurient” (sick or unhealthy) interest in sex or sexual matters; depicts sexual conduct in a “patently offensive way”; and, when taken as a whole, “lacks serious literary, artistic, political, or scientific value.”
Etymological Understanding a word or concept by tracing its roots in the same or other languages The word obscenity may derive from the Latin word obscaenus, combining the prefix ob (meaning “to”) and the word caenum (meaning “dirt,” “filth,” “mire,” and “excrement”).
Functional Defining a concept by examining how it is applied or how it functions In practice, American law recognizes obscenity as hard-core pornography (and, ironically, not as violence, disease, or other social ills).

You can exert maximum impact through description by using vivid language, presentation aids, and details that evoke the senses of sight, sound, smell, touch, and taste. This can be especially effective if you use it as a subpoint to engage listeners’ imaginations and place them in the middle of what you’re describing. (See Chapter 12 for more on effective description.)
