Lurch, often referred to as a stumble, is a sudden and unsteady movement that occurs when a person loses their balance. This can happen due to various reasons, such as tripping over an object, slipping on a surface, or experiencing a moment of dizziness. The body may sway or lean unexpectedly, leading to a brief but noticeable loss of stability. In some contexts, lurching can also describe a jerky or awkward motion, such as when a vehicle moves suddenly due to rough terrain. This term is commonly used in both everyday language and in discussions about physical coordination, balance, and movement disorders.
