A serious and heartfelt request or appeal, often made with a sense of urgency.
The priest made an adjuration for peace during the service.
Adjuration → It is formed from "ad-" (meaning to) and "jurare" (meaning to swear). The word "adjuration" refers to the act of earnestly urging someone to do something, often with a solemn promise or oath.
Think of someone 'swearing' ('jurare') to do something 'to' ('ad-') — that's why adjuration means earnestly urging someone with a solemn promise.
