A more thorough explanation:

Definition: Matricide is the act of killing one's own mother or a person who kills their mother. It is a serious crime and a form of homicide.

Examples:

• John was arrested for matricide after he killed his mother in a fit of rage.
• The police are investigating the case of matricide where a woman was found dead in her home and her son is the prime suspect.

The examples illustrate the definition of matricide as the intentional killing of one's own mother. In both cases, the perpetrator is accused of killing their mother, which is a heinous crime. Matricide is a rare occurrence, but it can happen due to various reasons such as mental illness, abuse, or revenge.
