• gash 本词

  Gash means to cut deeply into something, usually skin, leaving a long, open wound; it describes the depth and severity of an accidental cut rather than a deliberate slicing motion.

  gash 指深深割破某物（通常是皮肉），留下又长又深的伤口；强调伤口的深度和严重程度，多指意外造成的伤，而非有意的挥砍动作。

Slash and gash both mean to cut with a sharp tool. Slash describes a quick, forceful, sweeping cutting motion, and is also used figuratively, as in slashing prices. Gash describes a deep wound left by a cut, usually from an accident.

这两个词都表示“用利器把某物割开”，但语气和侧重不同：slash 强调挥动利器猛力切割的动作，且常用于比喻义（如大幅削减价格）；gash 强调切割后留下的深长伤口，多指意外造成的严重创伤，没有比喻用法。
