Rivalry refers to a competitive relationship between individuals, groups, or entities striving for the same goal or recognition. This competition can occur in various fields, such as sports, business, or academics, where rivals seek to outperform each other. The presence of rivalry often motivates participants to improve their skills and performance. In sports, for example, teams like the New York Yankees and Boston Red Sox have a long-standing rivalry that enhances the excitement of their games. Similarly, in business, companies like Coca-Cola and Pepsi compete for market share, driving innovation and marketing strategies.
