department: [15] English has borrowed department from French département on two completely separate occasions. Originally, in late Middle English, it was used for ‘departure’, but this died out in the mid-17th century. Then in the 18th century it was re-acquired in the different sense ‘distinct division’; Dr Johnson, in his Dictionary 1755, dismisses it as a French term.

French department meant "group of people" (as well as "departure"), from which English borrowed the sense of "separate division, separate business assigned to someone in a larger organization" (c. 1735).
