What term is used for an animal that has no brand or marking, and also for someone who dissents?

The term "maverick" refers to an animal, particularly cattle, that is unbranded and has no identifying marks. This term has also evolved to describe an individual who acts independently or expresses dissent from established norms or protocols. A maverick is someone who embodies nonconformity and often takes a stand that distinguishes them from mainstream or expected behavior.

This dual meaning makes "maverick" fitting as it successfully links the concept of unbranded animals to the idea of someone who diverges from conventional beliefs or practices. The richness of this term encapsulates both the original meaning related to livestock and the metaphorical usage in social contexts, highlighting independence and a willingness to challenge the status quo.
