Proscription is the noun: the official act of saying that something may not exist or be done, or the ban itself. “The proscription of that group” means the law or order that forbids it. In Roman history, a proscription was a published list of people who were outlawed — a terrifying public writing. Historians still use that special sense. In today’s news, proscription is a heavy, formal word for a ban, especially of organisations. Everyday English prefers ban or prohibition. Though actually, the Latin started as “writing out in front” — posting a notice. The “forbid” meaning grew from that public writing. So the noun still carries a paper-and-power feel: not a quiet no, but a declared, written shutting down.

禁令、禁止。古羅馬史裡也指把人寫進公敵名單的「公敵宣告」。
