Describing something that is forbidden or prohibited.

Interdictory → It is formed from "inter-" (meaning between) and "dicere" (meaning to say or declare). The word refers to something that declares or prohibits actions between parties.
Think of something that 'declares' ('dicere') a prohibition 'between' ('inter-') parties — that's what interdictory means.
