Perhaps via Old North French cant "corner" (itself perhaps via Middle Low German kante or Middle Dutch kant), from Vulgar Latin *canthus, from Latin cantus "iron tire of a wheel," which is possibly from a Celtic word meaning "rim of wheel, edge, brim" (compare Welsh cant "bordering of a circle, tire, edge," Breton cant "circle"). The ultimate connections of these are uncertain. Greek kanthos "corner of the eye," and Russian kutu "corner" sometimes are suggested, but there are difficulties (see Beekes).
1550s, "one given to change," from change (n.) + diminutive suffix -ling. Meaning "person or thing left in place of one secretly taken" is from 1560s; specific reference to an infant or young child (usually stupid, strange, or ugly) superstitiously believed to have been left by the faeries in place of a beautiful or charming one they have stolen away is from 1580s. An earlier word for it was oaf or auf.
