Malice aforethought
premeditation or predetermination of a crime, increasing the guilt or enormity of the crime

Malice aforethought is the "premeditation" or "predetermination" (with malice) required as an element of some crimes in some jurisdictions and a unique element for first-degree or aggravated murder in a few. Insofar as the term is still in use, it has a technical meaning that has changed substantially over time.
Etymology
The term malice aforethought is a direct translation of the Law French term malice prépensée, so the adjective follows the noun as in French.
Legal history
Malice aforethought was not an element of murder in early medieval English law cases. Both self-defence killings and death by misadventure were treated as murder by juries. Although pardons for self-defence became common after the Statute of Gloucester was passed in 1278, the jury in a 14th-century case still found that a self-defence killing was felonious.
In the 12th century, any death by misadventure without a "presentment of Englishry" was sufficient for a jury finding of murder, even in cases where there was no suspect and the victim's identity was unknown. The murder fine was levied in these cases under the Laws of Henry I until 1267, when the fine for death by misadventure was abolished by the Statute of Marlborough during the baronial reform movement. The primary meaning of murdurum continued to be murder fine until the fine was abolished by the Engleschrie Act 1340 (14 Edw. 3 Stat.
