What does "affordance" mean in UX design?

In UX design, "affordance" refers to the properties of an object that indicate how it can be used. This concept helps users understand the possible actions they can take with an interface or a product simply through its design. For example, a button might look raised and have a shadow, suggesting that it can be pressed, whereas a flat surface might imply that it should not be interacted with. When designers create products with clear affordances, they enhance usability by enabling users to intuitively understand how to engage with the interface without needing explicit instructions.

This understanding is crucial in creating intuitive designs that foster a positive user experience, as users can effortlessly navigate and utilize products based on visual cues and interactions.
