The word "accusative" comes from the Latin accūsātīvus, meaning "having been blamed," which is derived from the verb accūsō ("to blame"). Although it entered English in the mid-15th century via French and Norman influences, its original Latin form was actually a mistranslation of an Ancient Greek term.
