Etymology: Its Latin ancestor, "vicissitudo," meant simply alternation or change, with no sense of misfortune. Roman writers used it for the regular succession of things like day and night or the turning of the seasons. The idea of a turn or exchange lies at the heart of the Latin root "vicis," meaning a change, turn, or interchange. That same root sits behind several familiar English words. "Vice" in phrases like "vice versa" carries the sense of "in turn," and "vicar" comes from a Latin term for a substitute, someone standing in another's place. Across these relatives, the common thread is one thing taking the place of another. The modern sense of unpredictable reversals of fortune developed later, as the emphasis shifted from the orderly cycle to the sudden, unwelcome turns within it.
