An 'unopposable' digit cannot be moved to touch or grasp against other digits on the same hand or foot. It's the opposite of 'opposable.' Think of it as having fingers that can only move in one direction, making it difficult to hold things securely. Creatures with unopposable digits often rely on other methods for gripping and manipulating objects. An unopposable thumb makes everyday tasks significantly more challenging. It is like using mittens instead of gloves.
