IPA: //ˈmænˌslɔːtə//
KK: /ˈmænˌslɔːtər/
The act of killing someone without planning or intending to cause harm, often considered less serious than murder.
He was charged with manslaughter after the accident that led to the death of another person.
Manslaughter is formed from "man" (from Old English "mann", meaning human being) and "slaughter" (from Old English "sleaht", meaning killing or slaughter). The term refers to the act of killing a human being, typically without premeditation or malice aforethought.
Think of 'man' as referring to a human being and 'slaughter' as meaning to kill. This helps you remember that manslaughter is the act of killing a person.
