Farlex Partner Idioms Dictionary

long shot, (not by) a

(Not) a remote chance. Early firearms were notoriously inaccurate, and a shot from a distance rarely hit the target. In the late eighteenth and early nineteenth centuries a long shot meant just that, a shot fired from afar. By the late nineteenth century the term had been transferred to other improbable circumstances, such as a wild guess or, more specifically, a bet against considerable odds. From about 1865, however, it also meant far-fetched, as in this OED citation from Young Gentleman’s Magazine (1873): “This did not, however, suit her long-shot tactics.”
