Injury is a noun with several similar meanings, all involving physical harm or wrongdoing. If you’re not careful, your reckless bike riding could result in a crash that causes injury.

Injury often refers to physical damage, but it can be used more figuratively to describe something that's unjust or that causes harm that isn't physical. For example, your estranged grandfather might do you the injury of leaving you out of his will. The word injury comes from in-, meaning “not,” and the Latin root ius or iur, meaning “right.” So an injury is something that's not right — it's something that has gone wrong that leads to damage.
