“Qualities” and “characteristics” are terms often used interchangeably, but they have subtle differences in meaning.

1. Qualities:
   • Definition: Qualities refer to inherent or intrinsic attributes or features of something. These are essential traits that define the nature or essence of an object, person, or concept.
   • Usage: Qualities are often used to describe the fundamental nature or properties of something. For example, when you describe someone as having qualities like honesty, integrity, or kindness, you are referring to their essential traits or attributes.
   • Examples: The quality of a diamond might refer to its brilliance, clarity, or color. The quality of a person might include characteristics like honesty, intelligence, or creativity.
2. Characteristics:
   • Definition: Characteristics are observable features or attributes of something that help in identifying or distinguishing it from others. They can be both intrinsic and extrinsic.
   • Usage: Characteristics are often used to describe the visible, measurable, or identifiable features of something. These features can be specific to individuals, objects, or concepts.
   • Examples: The characteristics of a person might include physical traits like height, hair color, or eye color, as well as personality traits like extroversion or introversion. The characteristics of a product might include its size, shape, color, or functionality.

In summary, while qualities often refer to inherent or essential traits that define the nature of something, characteristics are more about observable features or attributes that help in identifying or describing it. Think of qualities as the fundamental nature of something, while characteristics are the visible or measurable aspects of that thing.
