defining characteristics

Key distinguishing features

Defining characteristics are the essential qualities that make something what it is—the features that distinguish one thing from another.

They answer the question "what makes this different?" A defining characteristic of mammals is nursing their young; a defining characteristic of a good leader might be decisiveness.

The phrase emphasizes traits that are fundamental rather than incidental: Patience is a defining characteristic of successful teachers.
