Esau Wood is the name of a character in a tongue-twister and acting exercise. In the exercise, a paragraph of text is presented to an actor. The text, although meaningful and grammatically correct, makes heavy use of homonyms and intentional obfuscation. The idea is that oration itself provides very few clues as to its meaning. Thus, in order for the text to be comprehensible to a listener, the actor must carefully place stress and emphasis in each sentence.
