قیاس (Analogy) is a cognitive process that involves comparing two different things to highlight similarities between them. It helps in understanding complex concepts by relating them to familiar ideas. For example, comparing the structure of an atom to a solar system can make the concept of atomic structure easier to grasp. In language and literature, analogies are often used to create vivid imagery or clarify ideas. They can enhance communication by providing relatable examples. For instance, saying "life is like a journey" helps convey the idea that life has various paths and experiences, making it more relatable to the audience.
