- thought of previously; premeditated (usually used predicatively): with malice aforethought.
- premeditation; forethought.
- (immediately postpositive) premeditated (esp in the phrase malice aforethought)
1580s, from afore + past tense of think. Apparently an English loan-translation of Old French legalese word prepense (see prepense) in malice prepense “malice aforethought” (Coke).
