KK: /koʊˈædʒʊtrɪks/
A woman who assists another, especially in a religious context, and may eventually take over her role.
The coadjutrix worked closely with the abbess to learn the responsibilities of the position.
Coadjutrix → It is formed from "co-" (meaning together) and "adjutrix" (from Latin "adjutrix", meaning helper or assistant, specifically a feminine form of "adjutor"). The word "coadjutrix" refers to a female assistant or helper working together with others.
Think of 'together' ('co-') and a 'female helper' ('adjutrix') — that's why coadjutrix means a female who assists or helps.
