What is the term for describing the ways in which two things are different?

The term used to describe the ways in which two things are different is "contrasting." This refers to the process of highlighting the differences between two or more elements, which can help in understanding their unique characteristics and distinguishing features. When contrasting items, one may focus on specific traits, qualities, or behaviors that set them apart from one another, thereby enhancing clarity and comprehension.

In contrast to the other options, "analogy" refers to a comparison made to show similarities between different things, rather than differences. "Comparing" involves noting both the similarities and differences between items and does not specifically emphasize only the differences. "Narrative," on the other hand, pertains to a story or account of events and is not related to comparing or contrasting items.
