The word "enjoin" entered Middle English via Old French "enjoindre," from Latin "iniungere" (in- "upon" + iungere "to join"). Originally, it meant "to impose a duty or command," reflecting the idea of binding someone to an action. Over time, it developed dual legal meanings: (1) ordering someone to act and (2) prohibiting an action—both rooted in the concept of binding by authority.
