Definition
Differentia refers to a characteristic that distinguishes one thing from others in the same general category. It's the specific attribute that sets it apart. Think of it as the defining feature that makes a species unique within its genus. It's about what makes something uniquely itself, distinct from similar things. For example, a bird's ability to fly is a differentia within the class of animals. It is not just about having a different feature, but about that feature being crucial to its identity or function. Thus, differentia defines the essence of an entity within its classification.
