payload

Etymology

It is a compound from English pay + load,^[2][3][4][5] and the OED compares the earlier paying load.^[2]

Earliest recorded meaning

A load carried by a vehicle, especially the part of it that earns revenue, such as passengers and cargo: 1914, in the Transactions of the Society of Automotive Engineers.^[2][6] Etymonline also dates the word by 1914, first of the paying part of a truck's load and later of an aircraft's.^[3] Dictionary.com dates it to 1925–30.^[5]

Semantic evolution

From the earning part of a truck's load, the word passed to aircraft;^[3] from 1920 it also meant the loading capacity of a vehicle.^[2] The military sense, the load of explosives carried by an aircraft or missile, is recorded from 1939 in the OED,^[2][7] while Etymonline dates the sense "bombs carried by a plane or missile" to 1936.^[3] Space travel gave it the load carried by a rocket, such as a manned capsule or a set of instruments, from 1952.^[2][7] In computing it came to mean the part of a virus or other malware that does the damage (1989) and the actual message carried in transmitted data, as opposed to a header (1990).^[2] Merriam-Webster also records a sense the financial burden of the regular payrolls of a business.^[6]
