Etymology: "Payload" is a compound of "pay" and "load," and its literal sense is close to what the two parts suggest: the portion of a vehicle's load that earns money for its owner. Freight, passengers, mail, or whatever a ship, train, truck, or aircraft carries for a fee is the revenue-bearing part of the load, as distinct from the fuel, equipment, and structure needed just to move it. The term dates from the early 20th century, when transport was becoming a commercial business and operators needed a way to separate paying cargo from the weight required to carry it. The sense then broadened beyond vehicles. Military and aerospace writers later applied it to the warheads a missile delivers, and to the instruments or experiments a spacecraft carries, which is why the word now turns up in both commercial and technical contexts.

Synonyms: cargo, load
