Opposites, or contrasts, refer to things that are completely different from each other. For example, hot and cold represent opposite temperatures, while light and dark describe different levels of brightness. These contrasting pairs help us understand the world by highlighting differences in characteristics, qualities, or states. In language, opposites are often used to create emphasis or clarify meaning. For instance, the words happy and sad convey distinct emotional states. By recognizing opposites, we can better appreciate the diversity of experiences and ideas, making communication more effective and engaging.
