wave
The word evokes a rhythmic, undulating motion. Whether it is the physical movement of the ocean or a hand in the air, there is an inherent sense of repetition and fluidity. It suggests a cycle of rising and falling, or a side-to-side oscillation that conveys a message or a natural force. In a social context, it is a low-effort, friendly signal that bridges a distance. In a psychological or social context, it describes a surge of emotion or a trend that arrives with intensity and then recedes, mimicking the behavior of the sea.
Countable when referring to individual crests of water or specific hand gestures. Uncountable when referring to the general phenomenon of radiation or energy, such as in light waves.
