An Affordance is a design element or feature that gives a clue about how it should be used, indicating the actions that are possible. In other words, an affordance is what a user can do with an object or interface element. For example, a door handle affords pulling or pushing (its shape suggests how you might grab and move it), and a button on a screen affords clicking or tapping. Good UX design ensures that affordances align with user expectations — if something looks like a button, users should be able to click it. Clear affordances make an interface intuitive by leveraging the user’s prior knowledge and instincts. A lack of affordance or misleading affordances (for instance, text that looks like a link but isn’t clickable) can confuse users and harm usability.
