Stumble, stagger and lurch all describe unsteady body movement. Stumble is a single misstep, often catching a foot. Stagger is a swaying, unsteady walk over several steps, from tiredness or drink. Lurch is one sudden, abrupt tilt, for vehicles. Other figurative meanings are not compared.

这三个词都可表示身体不稳的动作或姿态，但侧重不同：stumble 强调因绊到障碍物而突然失去平衡、踉跄一下；stagger 强调因疲惫、头晕或醉酒而连续摇晃行走；lurch 强调突然猛烈地倾斜或摇晃一下，常用于车辆。此处不比较 stumble 表示「说话结结巴巴」的引申义，也不比较 lurch 在习语「leave somebody in the lurch」（陷入困境，无人帮助）中的用法。
