‘急拐’ literally combines 急 (jí, meaning 'urgent' or 'sudden') and 拐 (guǎi, meaning 'to turn' or 'a bend'). Together, it describes a sudden, sharp change in direction—most commonly used for roads, paths, or vehicle movement where the turn is tight and requires immediate adjustment. It emphasizes both the abruptness and the narrow angle of the turn, often implying potential difficulty or danger if not navigated carefully.

This term appears frequently in driving instructions, road safety warnings, hiking trail descriptions, and urban navigation contexts. While it can occasionally describe figurative turns (e.g., in a story’s plot), its primary usage is physical and spatial. Unlike broader terms like 转弯 (zhuǎn wān, 'turn'), 急拐 specifically conveys urgency and tight geometry—think of a hairpin curve on a mountain road or a quick 90-degree alley turn in a crowded city.
