Gén.) an adoption of the English drive v., in its nautical sense ‘to drift with the stream or wind’ (compare Acts xxvii. 15), subsequently associated and identified in form with the pre-existing French verb dériver to derive v. In French applied both to the drift or driving of a ship, and (recently) to the drift or deviation of a projectile, and in the later use taken into modern English.Previous versions of the OED give the stress as: deriˈvation. Gunnery. The deviation of a projectile from its normal course due to its form, motion, the resistance of the air, or wind; spec. the constant inclination of a projectile to the right due to the right-hand spin imparted by the rifling; drift.
