An analogy is a comparison between two different things that highlights a similarity between them. It helps to explain a concept or idea by relating it to something more familiar. For example, saying that life is like a journey suggests that both involve progress, challenges, and experiences along the way. Analogies are often used in writing and speech to clarify complex ideas. They can make abstract concepts easier to understand by linking them to concrete examples. For instance, comparing a computer to a brain can illustrate how both process information, making the function of technology more relatable.
