A person who oversees and manages the jumping of parachutists from an aircraft, ensuring safety and proper procedures are followed.
The jumpmaster gave the final instructions before the paratroopers exited the plane.
Jumpmaster → It is formed from "jump" (from Middle English *jumpe*, meaning to leap or spring) and "master" (from Old French *maistre*, meaning one who has control or authority). The word "jumpmaster" refers to a person who has authority or expertise in jumping, particularly in parachuting or skydiving.
Think of someone who is an expert or has control ('master') over the act of leaping or springing ('jump'). This helps you remember that a jumpmaster is someone who guides or oversees jumps.
