What does wave mean?
A wave is a moving ridge or disturbance on the surface of water, such as a wave rolling toward a beach. The word also describes similar movements or oscillations in air, sound, light, radio signals, and even the surface of a solid object. In everyday figurative expressions, a wave can mean a brief period of intense emotion or activity, as in “a wave of relief” or “a wave of protests.” As a verb, wave means to move the hand in greeting, to signal, or to direct someone, as in “wave goodbye.” These meanings share an image of movement that travels or unfolds from one point to another. Wave is useful because it connects an ordinary physical phenomenon with broad metaphorical ideas about communication, emotion, change, and temporary social movements.
A moving ridge or series of ridges on the surface of water or another liquid; a similar disturbance or oscillation; a brief period of intense emotion or activity; or a gesture made by moving the hand.
