By hook or by crook

Origin

In medieval England, strict forest laws protected royal and noble hunting grounds, severely restricting commoners' access to timber. However, a customary right sometimes allowed villagers to gather firewood from these protected lands, but only what they could reach with a shepherd's crook (a curved staff) or pull down with a billhook (a cutting tool). This precise legal distinction—taking only fallen branches or deadwood easily accessible by these tools—drew a clear line between what was permissible and what was not. Over time, this specific legal loophole broadened into a general expression for achieving a goal by any means possible, whether through legitimate methods ("by hook") or less conventional, perhaps even illicit, ones ("by crook").
