Other forms: collaborators
A collaborator is somebody who works jointly with another, or who helps an enemy. A close collaborator, wartime collaborators, my collaborator on the book.
The two senses sit uncomfortably in one word, and which one is heard depends entirely on the context: in research it is a colleague, and in an occupied country it was a capital charge.
