staff: [OE] Staff is a widespread Germanic word, with relatives in German stab, Dutch and Swedish staf, and Danish stav. These point back to a common Germanic ancestor *stabaz. Its ancestral meaning is ‘stick’, and its use as a collective term for ‘employees’, which dates in English from the 18th century, probably originated as an allusion to the carrying of a staff or ‘stick’ of office by a person in charge of subordinates – who thus became subsumed metaphorically under the notion of his ‘staff’.
