noun - Aquaphobia is a persistent and abnormal fear of water. Aquaphobia is an anxiety disorder and a specific phobia that involves a level of fear that is beyond the patient's control or that may interfere with daily life. People suffer aquaphobia in many ways and may experience it even though they realize the water in an ocean, a river, or even a bathtub poses no imminent threat. They may avoid such activities as boating and swimming, or they may avoid swimming in the deep ocean despite having mastered basic swimming skills. This anxiety commonly extends to getting wet or splashed with water when it is unexpected, or being pushed or thrown into a body of water.
Of the simple phobias, aquaphobia is among the more common types.
Aquaphobia came from the Latin word aqua (which normally ought to have the form aqui- when used as a prefix) and the Greek word "phobia".
