English[edit]

Cyclone Kyarr over the Arabian Sea
Cyclone Fantala over the southwest Indian Ocean near Madagascar

Etymology[edit]

Coined by Henry Piddington, probably in the 1840s, and based on some term in Ancient Greek. Sources disagree on the date and on which Ancient Greek term, though it had to be something derived from either κύκλος (kúklos, circle, wheel) or κυκλόω (kuklóō, go around in a circle, form a circle, encircle), for example the present active participle κυκλῶν (kuklôn).
