A stab wound is a piercing injury caused by a sharp object, usually a knife or a blade. Synonyms for this term include puncture, thrust, laceration, gash, incision, and cut. These terms are often used interchangeably, but each has a slightly different implication. A puncture implies a small, deep hole made by a pointed object. A thrust suggests a forceful, deliberate action, while a laceration implies a jagged or torn wound. A gash is typically a long, deep cut that may require stitches, and an incision is a surgical cut made intentionally. When describing a stab wound, it's important to use precise language to convey the severity and nature of the injury.
