adj. relating to or being a speed greater than the speed of sound in air

The word "supersonic" combines the Latin-derived prefix "super-" (meaning "above" or "beyond") with "sonic," from the Latin "sonus" (sound). It was coined in the early 20th century to describe speeds exceeding the speed of sound (Mach 1). The term reflects technological progress in aviation, where breaking the sound barrier became a milestone. The prefix "super-" is widely used in scientific and technical contexts to denote excess or superiority (e.g., "superhuman," "superconductivity").

Supersonic travel reduces flight time significantly.
Engineers are designing quieter supersonic aircraft.
The Concorde was a famous supersonic passenger plane.
