Dictionary definition of cycle
A recurring sequence or pattern of events or actions that repeats itself over time.
"The water cycle is responsible for the continuous circulation of water on Earth."
Detailed meaning of cycle
It embodies the concept of repetition, where a set of activities or phenomena unfold in a cyclical manner, creating a continuous loop. Cycles can be observed in various domains, such as nature, science, economics, and even human behavior. In nature, we witness the cycle of seasons, where the same sequence of spring, summer, autumn, and winter repeats itself every year. Similarly, in science, the water cycle illustrates the continuous process of evaporation, condensation, and precipitation that sustains our planet's water resources. Economic cycles, such as the boom and bust cycles, depict the fluctuation of economic activity over time. Moreover, in human behavior, cycles can manifest in personal habits, emotional patterns, or societal trends. The notion of a cycle implies a sense of predictability, as events or actions tend to follow a predetermined order, offering opportunities for observation, analysis, and understanding.

History and etymology of cycle
The noun 'cycle' has its etymological roots in the Greek word 'kyklos,' which means 'circle' or 'ring.' In ancient Greece, 'kyklos' was often used to describe the shape of a wheel, reflecting the concept of something turning or revolving in a circular manner. Over time, this term evolved to encompass the idea of a recurring sequence or pattern of events or actions that repeats itself over time, much like the continuous, circular motion of a wheel. The etymology of 'cycle' underscores its historical connection to the notion of repetitive patterns, highlighting the cyclical nature of various processes and phenomena in the world, from natural seasons to economic cycles and the ongoing rhythms of life itself.
