Coulrophobia is the irrational fear of what?

The story behind the answer

Coulrophobia is the specific phobia of clowns, not tunnels, needles, or cemeteries. The term comes from Greek kōlobathristēs, meaning “stilt-walker,” a type of performer related to clowns, giving us the “coulro-” root.

People often fear clowns because heavy makeup and fixed smiles mask true facial expressions, creating an uncanny, unpredictable vibe; horror media and real-life infamy have reinforced this reaction. Like other specific phobias, it’s treatable with gradual exposure and cognitive-behavioral techniques. Memory tip: “coulro” sounds like “color”—think of clowns’ colorful wigs and makeup—or spot “CLOwn” hidden in couLROphobia.
