What are the similarities between assault and GBH?

Assault and grievous bodily harm (GBH) both involve the infliction of harm on another person, but they differ in severity and intent. Both offenses can stem from intentional actions, and in many legal systems, they may be prosecuted under similar frameworks. Additionally, both can cause physical and psychological harm to the victim. However, GBH typically involves more serious injury or the potential for significant harm compared to simple assault, which may not result in physical injury.
