trademark
This term functions as both a legal instrument and a descriptive label. In a legal sense, it refers to the formal registration of intellectual property to ensure exclusivity and prevent infringement in commerce. When used descriptively, it refers to a signature trait or a recurring habit that makes a person or entity instantly recognizable. This usage is often metaphorical, suggesting that a specific behavior has become a permanent brand associated with that individual.
