What does aeronaut mean?
An aeronaut is a person who travels through the air in a lighter-than-air craft, most commonly a balloon, though the term also covers airship crew. The word entered English in the late eighteenth century, just as the Montgolfier brothers' hot-air balloon made human flight possible for the first time, and it quickly became the standard name for these pioneers of the sky. Today 'aeronaut' has a distinctly historical and literary character: modern balloonists are more often simply called balloonists, but writers reach for 'aeronaut' when they want to evoke the daring, spectacle, and romance of early flight. Figures such as Jean-Pierre Blanchard and Sophie Blanchard are remembered as aeronauts, having ascended in hydrogen and hot-air balloons before powered aircraft existed. The word remains useful for anyone writing about aviation history, adventure literature, or the bold first age of human flight.

Etymology of aeronaut
The word 'aeronaut' derives from Greek roots: 'aero-' meaning air, and '-naut' meaning sailor or navigator, from 'nautes' (sailor). It was coined in French in the late eighteenth century — shortly after the first manned balloon flights of 1783 — and passed into English around the same period. The same '-naut' suffix later produced 'astronaut' and 'cosmonaut' for space travelers, making 'aeronaut' the original member of this family of sky-and-space voyager words.
