Relating to a curse or expressing a wish for evil to happen to someone.
The imprecatory psalms in the Bible call for divine punishment on the enemies of the faithful.
Imprecatory is formed from "imprecari" (meaning to invoke or call down) and the suffix "-ory" (meaning relating to or characterized by). The word describes something that is related to invoking a curse or expressing a wish for misfortune upon someone.
Think of 'invoking' a curse when you hear 'imprecatory' — it relates to calling down misfortune.
