A weaver has finished his training but does not yet have a workshop of his own, and works for wages in another man's shop. What was such a worker called?

Explanation

Completing the term of training earned the right to be paid for the work, but a workshop of one's own required formal admission to the top rank of the craft, so this middle position was that of a trained employee. Calling him a master fails because mastership was a standing granted by the guild after a test, not simply the point at which learning stopped.
