The relationship or status of being a coauthor, or the practice of writing or creating something together with one or more other people.
From 'coauthor' (co- + author) + '-ship' (a suffix meaning state or condition). The concept formalized as academic publishing grew and required clear attribution of who did what work.
Coauthorship can be tricky because you have to figure out who gets credit for what—does the person with the original idea count the same as the person who did all the experiments? Different fields have different rules!
