In a speech, saying "on the other hand" to indicate a contrasting idea is an example of a signpost. A signpost is a linguistic cue or signal that helps guide the audience through the structure of a speech or presentation. When a speaker uses phrases like "on the other hand," "in contrast," or "however," they are providing a clear indication that a shift in perspective or a contrasting point is about to be made.
Here's why "on the other hand" fits as a signpost:
1. **Transition**: It signals a transition from one idea to another.
2. **Contrast**: It highlights a difference or opposing viewpoint to what was previously discussed.
3. **Clarity**: It helps the audience follow the speaker's line of thought and understand the structure of the speech.
Therefore, in the context of a speech, using "on the other hand" is a strategic way to signal a change in direction or perspective, making it easier for the audience to follow along and grasp the contrasting ideas being presented.
