The Central Idea

Ask yourself . . .

"What is my personal view of my topic?"

"What do I want my audience to remember about my speech?"

The answer to both questions is your central idea (or thesis)

The central idea . . .

is always a complete sentence (never a fragment, never a question)

often takes the form of a personal point of view or opinion

Ineffective: "Spiderman is a fictional hero who fights the villains in a corrupt world." (There is no personal perspective here, just a description of who Spiderman is.)

Effective: "Spiderman is a fictional hero who reminds us that great power also brings great responsibility."  (This sentence states a personal perspective, an opinion, that a speaker can develop.)

avoids imprecise language

Ineffective: "Mexico's Yucatan peninsula is an awesome place to spend a vacation." ("Awesome" meaning what exactly?)

Effective: "Mexico's Yucatan peninsula attracts visitors with its warm climate, excellent food, and extensive Mayan ruins." (This sentence states an opinion in a form that can be developed in three main points.)

Everything you say in the speech . . .

explains

develops

illustrates

. . . the central idea.

Useful Tips . . .

Delay writing the central idea until you first know what your main points will be.

Be sure the central idea is delivered in the speech, usually at the end of the introduction.

Make a separate card stating the central idea to include with your speaking notes.
