Word History

Etymology

borrowed from Medieval Latin, "pustule, pox," going back to Late Latin, "pustule," from varius "affected by pox, leprous" (adjective derivative of varus "pimple" + Latin -ola, variant of -ula -ule after vowels) — more at varix

Note: Late Latin varius is very likely independent of classical varius "having contrasting colors, varied" (see various entry 1).
