**Traineeship** → It is formed from "trainee" (from the verb "train", which comes from Old French *traïner*, meaning to drag or pull) and "-ship" (meaning the state or condition of). The word "traineeship" refers to the state or condition of being a trainee, typically in a training program or apprenticeship.
