What is the purpose of using "analogy" in communication?

The purpose of using "analogy" in communication is to simplify complex ideas by drawing a comparison between two different concepts that share similar characteristics. This technique helps to clarify and make the new or complicated information more relatable and understandable to the audience. Analogies can bridge the gap between unfamiliar and familiar ideas, enabling the communicator to convey thoughts in an accessible manner. For instance, explaining a difficult scientific concept may be done by comparing it to something more commonplace and easy to grasp, thereby enhancing comprehension.

The other options focus on different aspects of literary technique. Creating characters is more aligned with characterization and developing narratives. Establishing themes involves underlying messages or concepts in a work and does not specifically deal with the comparative nature of analogy. Developing a narrative arc pertains to the structure of storytelling rather than the simplification of ideas. Thus, while these methods are essential in communication and literature, they do not fulfill the specific function of analogy as effectively as simplifying complex ideas does.
