A leopard cannot change its spots

"A leopard cannot change its spots" is a proverbial expression conveying the idea that fundamental characteristics or traits of a person or thing are unlikely to change. It suggests that inherent qualities or behaviors, similar to the spots on a leopard's coat, are ingrained and difficult to alter. This saying implies skepticism toward the possibility of significant transformation or reform in individuals who have demonstrated consistent patterns of behavior. It serves as a caution against expecting drastic changes in someone's personality or behavior, especially if they have exhibited certain traits over an extended period. Ultimately, it underscores the idea that people are often defined by their inherent nature or tendencies, which may be challenging or impossible to change.
