Balance aid

EAR

Think of the body part that helps you stay steady when you tilt your head or move quickly. It’s not your feet or hands.

"Balance aid" hints at something that helps you keep your equilibrium, and your ear plays a key role in that—it contains the vestibular system, which controls balance. The clue cleverly plays on the double meaning of "ear" as both the body part and a homophone for "air," though here it’s purely about the anatomical function. It’s a straightforward definition with a slight twist, relying on basic biology rather than wordplay.
