Main Entry: ka·ty·did
Etymology: imitation : any of various large green American grasshoppers with very long antennae and males that make a shrill noise using sound-producing organs on the forewings Word History Some animal names have been created through imitation of the sounds the animals make. The name katydid is an example of this process. These insects were given this name because the noise they make was thought of as sounding like "Katy-did, Katy-didn't" repeated over and over.
