| 释义 | cyclic (once / 21335 pages) 1adj 2adj 3adj The adjective cyclic describes something that happens so regularly, you can predict it, like the cyclic trips to buy notebooks and sneakers when preparing for a new school year. Accent the first syllable in cyclic: "SICK-lick." Something that is cyclic follows a cycle, a sequence in which things begin and end in a predictable rhythm. Cycle comes from the Greek word kyklos, meaning "circle, wheel, any circular body, circular motion, cycle of events." So something that is cyclic shares that same pattern.
