Traits are the characteristics or qualities that define a person, animal, or object. For example, a dog might have traits like being friendly, loyal, or playful. These traits help us understand how someone or something behaves and interacts with the world around them. In humans, traits can be physical, like eye color or height, or they can be personality traits, such as being kind, adventurous, or shy. Understanding traits is important because they shape our relationships and influence how we perceive ourselves and others.
