How does repetition enhance a speech?

Repetition enhances a speech primarily by reinforcing key ideas for the audience. When a speaker reiterates important points throughout their presentation, it helps to cement these ideas in the minds of listeners, making them more memorable. This technique is particularly effective in ensuring that the audience understands and retains the main messages of the speech. By highlighting crucial concepts multiple times, the speaker can create a stronger impact and ensure that these points are understood and remembered long after the speech has concluded. This method is a powerful rhetorical strategy often employed in effective public speaking to emphasize significance and drive home the main themes.

In contrast, other answers suggest that repetition may lead to negative outcomes, such as making the speaker seem less prepared or decreasing interest, which is not the intent of thoughtful repetition in speechmaking.
