An analogy is a comparison between two different things that highlights their similarities. It often helps to clarify an idea or concept by showing how it relates to something more familiar. For example, you might use an analogy to explain a difficult scientific principle by comparing it to something in everyday life, making it easier for others to understand.
The word "analogy" comes from the Greek word "analogĂa," which means "proportion" or "correspondence." The prefix "ana-" means "up" or "back," while "logos" means "reason" or "word," together suggesting a reasoning that draws on relationships.
