The term CARNIVAL AMUSEMENT can be broken down into two parts: 'RIDE' (4 letters) and 'CARNIVAL'. A RIDE is an amusement park attraction that people can RIDE for fun or entertainment. CARNIVAL rides are usually found at carnivals, fairs, and festivals. They are typically mechanical devices that move people around in circles, up and down, or back and forth. Common examples of CARNIVAL rides include roller coasters, Ferris wheels, carousels, and bumper cars.
