Did you know?
Continual existence—that elusive philosophical concept is reflected in perpetuity, which traces to Latin perpetuus, an adjective meaning "continual" or "uninterrupted." The word has specific legal use. It can refer, for example, to an arrangement in a will rendering land forever incapable of being surrendered or transferred (or at least, for a period longer than is set by rules against such arrangements) or to an annuity that is payable forever.
