Clarity is a product feature.
The best interfaces reduce uncertainty before they add capability.
People rarely experience a product as a list of features. They experience a sequence of questions: Where am I? What can I do? What happened? What happens next?
An interface feels clear when it answers those questions at the moment they appear. This is less about minimalism than about information arriving in the right order.
Make state visible
Systems know far more about their state than they usually communicate. A small status label, a useful empty state, or a precise error can prevent a user from forming the wrong mental model.
Prefer recognition
Clear language, stable placement, and familiar patterns lower the amount of information someone must hold in memory. Novel interaction can be valuable, but it should pay for the extra attention it asks for.
Clarity compounds. It lowers support cost, makes new features easier to discover, and gives people confidence that the product will behave as expected.
