What is the primary purpose of a thesis statement in a speech?

The primary purpose of a thesis statement in a speech is to provide a clear main idea. A thesis statement acts as a roadmap for the audience, highlighting the central point the speaker intends to communicate. It encapsulates the essence of the speech in a concise manner, allowing the audience to grasp what to expect in terms of content and direction. By having a well-defined thesis statement, the speaker ensures that the audience can easily follow along and understand the key arguments or messages being conveyed throughout the presentation. This clarity is crucial in oral communication, as it helps maintain focus and coherence in the speech, guiding both the speaker and the audience toward a common understanding of the topic.
