At the bottom of cycle is a circle — and a wheel: Greek kyklos means both. From that one shape come two lines: things that go round and return to the start, and a thing you ride.
From the word’s history
From Greek kyklos 'circle, wheel', also 'a round of events'. That single root holds both pictures: things that recur in a loop, and the wheeled bicycle.
cycle 來自希臘文 kyklos,意思同時是「圓圈、車輪」,也指「一輪接一輪的循環」。這一個字根同時撐起兩個畫面:週而復始的循環,以及有輪子的腳踏車。
