IPA: /ˌɪn.təˈdɪk.ʃən/
KK: /ˌɪntərˈdɪkʃən/
The act of prohibiting or forbidding something, often by authority or law.
The government issued an interdiction against the sale of certain chemicals.
Interdiction → It is formed from "inter-" (meaning between) and "dicere" (meaning to say or declare). The word refers to a declaration that prohibits or forbids something, effectively saying that something is not allowed between parties.
Think of a declaration ('dicere') that is made 'between' ('inter-') parties to prohibit something — that's what interdiction means.
