claustrophobia

Claustrophobia is an irrational or abnormal fear of being in an enclosed space. If your heart races in an elevator, or you break out in a cold sweat in a walk-in closet, you might have claustrophobia.

Claustrophobia is made of ancient Latin words. Phobia means "fear," and claustro means "bolt" — the kind you put on a door. Broadly speaking, the opposite of claustrophobia is agoraphobia, which is the fear of open spaces. For fun, try adding "-phobia" to your own personal source of dread! For example, “math-phobia.”
