cycle

cycle: [14] Cycle is one of a wide range of English words (including pole, colony, and cult) which go back ultimately to the Indo-European base *qwel-, *qwol-, which signified ‘move around’. Its reduplicated form, *qweqwlo-, produced English wheel, Sanskrit cakrá- ‘wheel, circle’ (ultimate source of the polo term chukker [19]), and Greek kúklos ‘circle’.

English acquired this via French cycle or late Latin cyclus. Its use as a cover term for bicycles, tricycles, etc (of which words in this context it is an abbreviation) dates from the late 19th century. Related forms in English include cyclone ‘mass of rapidly circulating wind’ [19] (probably a modification of Greek kúklōma), cyclamen [16] (so named from its bulbous roots), and encyclopedia. _ BICYCLE, CHUKKER, COLONY, CULT, ENCYCLOPEDIA, POLE, WHEEL.
