What is the primary purpose of speech according to the content provided?

The primary purpose of speech is to express thoughts. This encompasses a wide range of communication, allowing individuals to convey their ideas, feelings, and perspectives to others. Expressing thoughts through speech is essential for effective interaction and helps to build connections between speakers and their audiences. By articulating thoughts clearly, speakers can engage listeners, provoke reflection, and foster understanding among diverse groups.

While options like entertaining or informing are also valid purposes of speech, they fall under the broader category of expressing thoughts. For instance, an entertaining speech still relies on the delivery of thoughts and emotions to keep the audience engaged, while informative speeches serve the purpose of sharing knowledge and insights, which ultimately stems from the speaker's thoughts on the topic.
