Illustrators. By definition, illustrators demonstrate the verbal messages they accompany. Waving a hand to say "hello" is an example of an illustrator. Illustrators are also used to communicate dimensions or direction. When asked to describe the length or width of an object, a person might hold out her hands or separate her thumb and forefinger to illustrate the measurement.
