What does drawing a parallel between two things signify in communication?

Drawing a parallel between two things in communication signifies an analogy. An analogy is a figure of speech that establishes a relationship based on similarities between two concepts. It helps to explain or clarify an idea by comparing it to something more familiar or simpler to understand. This technique is often employed in persuasive communication and storytelling to create connections and enhance comprehension for the audience.

While comparison and similarity also share elements of connection, they lack the depth and purpose that an analogy provides. A comparison simply refers to examining the similarities or differences between two subjects, whereas similarity focuses specifically on what is alike. An analogy, however, goes further by using those similarities to provide insight or draw conclusions about one of the subjects in relation to the other. Therefore, in the context of communication, using an analogy is the most fitting choice, as it conveys a more nuanced and meaningful relationship.
