1) v. the threat or attempt to strike another, whether successful or not, provided the target is aware of the danger. The assaulter must be reasonably capable of carrying through the attack. In some states if the assault is with a deadly weapon (such as sniping with a rifle), the intended victim does not need to know of the peril. Other state laws distinguish between different degrees (first or second) of assault depending on whether there is actual hitting, injury or just a threat. "Aggravated assault" is an attack connected with the commission of another crime, such as beating a clerk during a robbery or a particularly vicious attack. 2) n. the act of committing an assault, as in "there was an assault down on Third Avenue." Assault is both a criminal wrong, for which one may be charged and tried, and civil wrong for which the target may sue for damages due to the assault, including for mental distress.
