The office, position, or status of being a coadjutor; the relationship or role of sharing duties with another person.
From coadjutor + -ship (denoting a state, condition, or office). The -ship suffix created noun forms for ranks and positions, especially in ecclesiastical and governmental hierarchies during Medieval times.
If you were promoted to 'coadjutorship,' you officially had legal authority to make decisions alongside your superior—it's not just helping, it's having actual power!
